Is 1000 calories a day healthy: Are Very Low-Calorie Diets Safe for Weight Loss?


Calories: How to Know if You Go Too Low – Weight Center

Cutting calories is the approach most dieters must take to meet their weight-loss goals. But every once in a while people take calorie restriction too far, ultimately making weight loss slower and more difficult by slowing your metabolism.

Figuring out the right number of calories for you on a daily basis depends on your age, gender, and activity level. In general, the younger and more active you are, the more calories you can consume. And men are able to eat more calories daily than women. For example, the U.S. Department of Agriculture guidelines says that women 19 to 30 years old should consume 2,000 calories if they have a sedentary lifestyle or 2,400 calories if they have an active one; for men of the same age the range is 2,400 to 3,000 calories.

Defining the Low-Calorie Diet

It seems logical that if calories are the problem, you would want to eat as few of them as possible to speed weight loss. As a general rule, people need a minimum of 1,200 calories daily to stay healthy. People who have a strenuous fitness routine or perform many daily activities need more calories. If you have reduced your calorie intake below 1,200 calories a day, you could be hurting your body in addition to your weight-loss plans.

“The big picture is to consume enough calories with a balance of nutrients and engage in physical activity for good health management to achieve one’s weight goals. Consuming less than 1,200 calories per day may make it difficult to meet vitamin and mineral needs via food,” says nutrition therapist Andrea Spivack, MA, RD, LDN, with Penn Behavioral Health at the University of Pennsylvania in Philadelphia.

Tempting as it may be to continue with your low-calorie weight-loss plan and simply take a supplement, Spivack points out that there are some key nutrients which are only available through your diet.

Occasionally, obese people will go on a very low-calorie diet — 800 to 1,000 calories per day — for a brief period of time in order to achieve a specific weight-loss goal, but then will switch to a diet with more calories to reach and maintain their desired weight. Such a diet is usually supervised by a doctor or nutritionist so that it is nutritionally balanced. Unfortunately, weight regain is common after these restricted calorie diets end.

Why Low-Calorie Diets Slow Your Metabolism

If you are on a very low-calorie diet, you may wonder why the numbers on your scale aren’t budging, but your diet buddy is slimmer by the month.

The reality is that different people respond differently to low-calorie diets. When your body senses that food may not be in plentiful supply, it may slow down your metabolism as protection against the possibility of starvation, even if you are obese and deliberately trying to lose weight.

The 411 on Calories – Weight Center

If you’re interested in nutrition or weight loss, you no doubt pay a lot of attention to calories. But do you know what exactly calories are, and how many you really need?

Calories: The Good, the Bad, and the Empty

There is really no such thing as “good” or “bad” calories. “Your body processes each calorie the same,” says Kimberly Lummus, MS, RD, Texas Dietetic Association media representative and public relations coordinator for the Austin Dietetic Association in Austin, Texas. But Lummus adds that some foods are far more nutritious than others. “We strive to make our calories the most nutrient-dense that we can, meaning that we are packing in a lot of nutrition for a very small amount of calories. You are optimizing your calorie budget, so to speak.”

While calories get a negative rap when it comes to weight control, calories are actually an important source of fuel you cannot live without. “Your body needs calories for energy,” says Lummus. Calories are the force behind everything we do, including eating, sleeping, and breathing.

“Calories are how much energy your body gets from the food and beverages that it consumes,” says Lummus. Most food sources are composed of some combination of carbohydrates, fats, and proteins, and each of these nutrients contains calories. Yet it’s important to stay away from “empty” calories in foods like sweets and soda, warns Lummus.

Calories: Finding Your Magic Number

You must find the right balance of calories every day, depending on your overall goals. “Eating too many calories and not burning enough through physical activities would yield a weight gain, while not eating enough calories [to keep up with your calorie burn] would yield a weight loss,” says Lummus.

The number of calories a person needs depends on many individual factors, including age, weight, height, and activity level. When dieticians counsel clients on calorie needs, they take all of these facts into consideration and come up with a suggestion for how many calories are needed to maintain, lose, or gain weight.

In general, men need between 2,000 to 2,400 calories and woman between 1,200 and 1,500 calories per day. Consuming less than 1,200 calories per day can be harmful to your health, notes Lummus, since it may trigger your body to go into starvation mode, causing your body to actually hold onto calories.

Teenagers’ caloric needs can vary considerably. For example, teenage boys may require up to 3,000 calories per day, while teenage girls usually need around 2,200 calories each day. “For children, calorie needs are going to change a lot more because they are growing so rapidly,” Lummus continues. She says that infants 5 to 12 months of age need around 850 calories daily, 1- to 3-year-olds need roughly 1,300 calories daily, 4- to 6-year-olds need about 1,800 calories daily, and 7- to 10-year-olds require 2,000 calories daily.

“Counting calories is usually not necessary for children,” says Lummus. “You just want to make sure that your child is getting all of the requirements from all of the food groups.”

Both children and adults should get the bulk of their calories from a variety of healthful foods, including low-fat or fat-free dairy products, fruits and vegetables, whole grains, and lean protein sources — the building blocks of a nutritious diet.

Low-Calorie Diets Mean High-Quality Lives, Research Shows

What Is a Low-Calorie Diet?

A low-calorie diet is one that restricts your intake to 1,200 to 1,600 calories per day for men, and 1,000 to 1,200 calories per day for women. Some people go on a very low-calorie diet for rapid weight loss, often consuming only 800 calories a day. This type of diet usually includes special foods such as shakes, bars, or soups to replace meals and for added vitamins. Very low-calorie diets can help a person achieve weight loss of up to 3 to 5 pounds per week.

For weight loss, most people should consider a low-calorie diet rather than a very low-calorie diet. Less extreme diets are easier to follow, they interrupt normal daily activities less, and are less risky if you’re over 50 or have other health problems. In addition, gallstones have been reported in people who go on very low-calorie diets.

Keep in mind that most diets only work when you make healthy lifestyle choices at the same time, including increasing daily exercise and reducing your sedentary time throughout the day.

Good Reasons to Try a Low-Calorie Diet

The obvious reason to restrict calories is to help with weight loss. Why else give up something that you enjoy? Yet very interesting data from animal studies throughout the animal kingdom shows additional effects of calorie reduction. As reviewed in Molecular Aspects of Medicine in June 2011, studies show that animals subjected to periods of calorie restriction, including primates, have:

  • Longer lives
  • Higher levels of physical activity
  • Lower rates of cancer
  • Less age-related degeneration of the brain
  • Improved reproductive performance

Some of these findings may seem odd to anyone who’s tried to fast or restrict their calories and then felt the early fatigue, weakness, lack of energy, nausea, and stomach pains associated with their efforts.

Keep in mind that the animal studies and observations involved regular periods of calorie restriction followed by, or within the context of, a healthy diet. In other words, the animals’ bodies had time to adapt in a healthy manner to slightly less caloric intake over a long period of time.

What Happens When People Restrict Calories?

When I talk with patients about cutting calories for heart health, I don’t think I’ve had anybody tell me they want to do it to live longer, feel better, and have a better quality of life. But this is because most people think of exactly how they’re going to feel the first few days or weeks after they start, rather than taking a long-term outlook.

A study published in June 2016 in JAMA Internal Medicine provided unique insight into what happens to people when they restrict their calories. This study included people who were not obese specifically because weight loss in obese people is often used to lower risk of diabetes, high blood pressure, sleep apnea, and coronary artery disease in addition to improving their quality of life.

The investigators in this study followed 218 participants for two years. The average age was 38, and 70 percent were women. At the time of enrollment, they could have a body mass index (BMI) up to 28, but no lower than 22. The groups were randomized to either continue with their normal diet or participate in a calorie-restricted diet. The diet contained approximately 25 percent fewer calories than they had previously eaten.

Why did the researchers choose a 25 percent reduction in calories? They thought this level was the most that could be reduced and sustained for the entire two-year study. Participants met in groups and had web-based resources to assist with their diet. Registered dietitians monitored participants’ weekly food diaries to determine total calories. All participants were encouraged to exercise at least five days a week for 30 minutes at a time.

The authors reported several important findings. First, and not too surprisingly, the people in the group who ate fewer calories lost more weight. On average, people in this group lost 7. 6 kg (16.7 lbs) compared to those in the other group, who lost 0.4 kg (0.9 lbs).

What was even more interesting was the impact of calorie restriction on quality of life. Those who restricted calories reported better moods and less daily tension, and they rated their overall health better throughout the study period.

The calorie-restricted group also reported improved sleep duration and quality. Finally, the calorie-restricted group experienced more sexual drive and arousal, and better sexual relationships, than the other group.

Is a Low-Calorie Diet Right for You?

If you’re overweight or obese, the choice may be simple. Weight loss is a critical lifestyle choice to improve your general health and lower your risk of cardiovascular disease, diabetes, sleep apnea, premature joint disease, high blood pressure, and cancer.

But lowering your risk for these diseases is only part of the potential benefit of cutting calories. Many other benefits of calorie restriction can improve your qualify of life and daily functioning. If you’re in the normal weight range, this new study also suggests a potential benefit of calorie restriction if done carefully — as long as your BMI doesn’t drop below 22.

If you chose to cut your calories, consider the expertise of the study investigators in this trial and aim for a 25 percent reduction. This is the level at which there was some benefit and that was at the same time tolerable, so it’s possible to keep it up. Here’s how to get started:

  • Keep an accurate diary of your food intake for one to two weeks.
  • Use an online calorie counter to help you determine your daily calorie intake.
  • Plan to restrict your calorie intake by 25 percent over the next month.
  • Write out a menu each week that includes a wide variety of foods that you enjoy.

One of the easiest ways to cut calories is to increase your intake of whole fruits and vegetables, which you’ll find are more filling and less calorie dense. Also consider making these diet changes with other people, who can provide social support and accountability — powerful ways to improve the likelihood that you’ll succeed.

As you begin to experience the improved quality of life, sleep, and other benefits, these will help positively reinforce your goals and make the calorie-restricted diet a daily habit. And as you feel better, become more active, and maintain a healthy diet, you’ll have the added benefit of having to see your local cardiologist less.

What Happened When I Followed a 1000 Calorie Diet…

In life there are all kinds of accepted ‘truths’ which are factually incorrect. Fitness and nutrition is full of them… ‘don’t eat carbs after 6’, ‘don’t arch your back when deadlifting’, ‘stretch before exercise’ etc etc. Most of these ‘rules’ turn out not to be true when put to the test, but they still persist in many quarters.

There’s another one recently that I wanted to test in nutrition, which was ‘don’t under-eat or you’ll lose your muscle’. I wanted to eat a 1000 calorie diet to see what the effects would be.

This one is particularly interesting to me, for a number of reasons…

  1. It contradicts a lot of the research around fasting.
  2. All diets are a form of under-eating, so is it really that bad?
  3. Who has proved the rule?

The thing is, single gram of fat contains 9 calories. If a person was carrying 20kg of fat tissue (which lots of people are), then they have 180,000 calories of potential stored energy in the form of fat tissue.

If a man burned 3000 calories per day, theoretically he could live for 60 days on his stored fat reserves alone!

There was a case in the 1960’s where a man fasted for 382 days. That’s correct – he lived for over a year without food, under medical supervision. You can read the study here.

Using this as a starting point, we know that fasting is absolutely fine. Many people use intermittent fasting anyway, going anywhere between 8 hours and 1.5 days at a time without eating. That’s their daily routine, not a special weight loss approach.

Using those examples as a base for comparison, 1000 calories per day is positively gluttonous.

Low Calories In Sport

It’s been well-known in weight-class sports for a long time that an athlete who has to reach a weight category can survive and perform on low calories. One of the common approaches is to increase micronutrient (vitamins and minerals) intake dramatically to offset any likely issues stemming from low general calorie intake.

It works, but it’s certainly not a long-term strategy for an athlete, maintaining extreme low calories with a very high training load.

Now, with this in mind I got in touch with a friend of mine, Jordan. He is a sports performance nutritionist for a HUGE (I won’t say which one) nutrition company. He’s my go-to source of nutrition info when I have a question. Before I made my mind up if I was going to experiment with low calories, I thought I’d run it by him.

Anyway, this is what happened in our recent convo…

So, there we go. A clinical nutritionist who works with professional athletes says it’s OK.

Good start.

Next up, I’d have to decide the approach I’d take. Of course the obvious thing is you just eat less, but that’s a little too simplistic. If I’m going to eat little but still perform well, I can’t rely on just filling my pie-hole with garbage. I had to be a little more tactical.

I usually eat around 3000 calories per day, so my thinking was to make the experiment a 1000 calorie diet for 5 days. Long enough to see an effect, short enough that the end of the diet was in sight. In reality 5 days doesn’t take a huge amount of discipline, so I opted for that.

I decided to start with accepted good practice, which dictates that if you are going to eat very low calories, it’s a good idea to over-compensate with high micronutrient intake. I always take a multivitamin anyway, but in this case I decided to go for an extra powerful multivitamin.

Next up was the omega issue. I’m allergic to fish, so I can’t eat it. I do see the value in an omega supplement though, so I look this one….

Finally, I wanted to take a greens drink that doubled as two things… a breakfast drink and an extra dose of multivitamins and minerals. I like both Athletic Greens and Lean Greens, but opted for Lean Greens on account of price alone.

So that’s my vitamins and minerals sorted. You may argue it’s overkill and in reality, it probably was. Still, I saw it as insurance, following good practice and a case of better being safe than sorry. It worked too, as we’ll go into later in the article.

The 1000 Calorie Diet Strategy

I think it’s important to have a plan when you go into anything like this – it’s such a dramatic change in practice that it can be really, really difficult if you don’t have a strategy before you head into it.

I had to balance two main issues…

  1. Give myself enough energy to train and recover well.
  2. Eat only enough to hit close to 1000 calories, but try to avoid hunger.

I wasn’t counting my macros, but I was counting my calories. I did that using My Fitness Pal and by checking the labels on food.

Given it was only ever going to be a short-term experiment (5 days), I was happy to occasionally go with decent quality ready meal options such as soups etc, mostly because it took the work out of counting the calories for me. I’m a sucker for the convenience, so that won out in the end!

On a normal week I’ll train around 5 times and according to my heart rate monitor, I’ll burn anywhere between 500 and 1000 calories per workout, depending on the session. I was willing to accept that and still only eat 1000 calories, given part of the nature of this experiment was the extremity of it all.

I needed fuel to train and recover, so decided to base my meal strategy around my exercise – essentially splitting my food intake across two meals, a small one before training and the larger one afterwards. Physiologically and socially, this approached really worked for me during the experiment. Here’s why….

  1. I don’t really eat breakfast. I’ve never been a big breakfast fan, unless I’m on holiday and can relax into it. Usually I’m up early, we’ve got kids to feed/wash/dress/transport and I start work early. Breakfast is an afterthought in at least 80% of cases, which meant eating only two meals was easy. I was having a greens drink in the morning, so ‘breakfast’ was covered.
  2. I can’t train very well on a full stomach. I like to eat some food before training, but not a huge amount. Basically I want enough to get me through a workout and not much else. My training doesn’t really require it either.
  3. Immediately post-training, I’m usually not very hungry. I can leave eating a big meal for good while after exercise. I’ll usually have a small snack, but not sit down to a big meal for a good few hours afterwards.
  4. I like to eat something substantial in the evening, so saving more of my calories for the end of the day works for me. It’s also when Rach and I eat our biggest meal, so it made life socially easier.

My general meal guideline was that it needed to contain protein, but also had to be generally healthy because that gave me more volume of food per calorie, something that I later learnt to be key in the success of all of this.

What happened when I ate a 1000 calorie diet….

Day 1 on a 1000 Calorie Diet

The first day was easy – I was already fuelled from the day before, plus I hadn’t ‘endured’ a few days of low calories, so in reality it felt like a single day of eating only 1000 calories, which is exactly what it was.

Day 2 on a 1000 Calorie Diet

At this point I had to think a little more. I was hungrier, but it wasn’t too bad. I learnt that if you keep plenty of water handy, you can get away with a little more distance between meals.

Day 3 on a 1000 Calorie Diet

I wasn’t especially hungry, but I was giving my food choice a LOT more thought. It made my eating far more conscious. When I was picking my early meal it was based purely on volume – which choice would give me the largest volume of food for the lowest number of calories.

Day 4 on a 1000 Calorie Diet

This was when it started to get tougher. I play football on a Thursday, so knew I was going to need some energy. It was by now that I was missing the snacks I’d usually eat throughout the day and it took some serious willpower (despite me thinking it’s a myth) to not eat the snacks.

Day 5 on a 1000 Calorie Diet

The last day was easier again, probably because I’d found a way to make it (kind of) work for me. Also the fact that the end of the experiment was in sight made it psychologically easier too. My weight loss was quite apparent by this point.

The Results of the 1000 Calorie Diet Experiment

There are three ways to look at the results of a 1000 calorie diet…

  1. Weight loss effects
  2. Performance effects
  3. Behavioural effects

Each of them are valid in their own right and are relevant depending on the lens through which you assess the virtues of a nutritional plan.

I didn’t have a bias beforehand – I was simply doing it as an experiment to test accepted wisdom. Thanks to this, I feel like I can offered a balanced opinion on the three effects I experienced.

Weight loss on a 1000 calorie diet

I started the week weighing 94.5kg and I ended it weighing 90.7kg, so I dropped 3.8kg, or just over 8lbs in old money.

It’s important to point out that this wouldn’t all have been fat, it would mostly be water weight. My motivation wasn’t weight loss, as I’ve said before. It’s an interesting outcome, but anyone using the approach to simply lose weight would probably be better off with a slower, more long-term approach which would see more fat lost.

Once I reverted to my normal eating, I regained some weight, but only around 1kg. With that in mind it’s probably appropriate to recommend this as a kick-start to weight loss, rather than a long term approach.

I’ve had a few people ask me how accurate my weight loss was, and I can tell them honestly it’s pretty bang on – I used these scales from Archon and have tested them with kettlebells and dumbbells that I know to be accurately weighed and they read the same figure…

Performance effects on a 1000 Calorie Diet

I expected there to be a dramatic effect on performance with the 1000 calorie diet and there was – to a degree.

Most of my training is quite explosive, with the vast majority of my training consisting of weight lifting and it’s variations. I do cardio in the form of football (which is very high intensity), but most of the training I do is quite glycolytic (anaerobic or ‘without oxygen’). Basically this means the effort is short, but very high intensity.

For this kind of training, I don’t need huge sugar/fuel reserves, so I noticed that as long as I had some fuel on board, I was fine.

It was much tougher playing football on the 1000 calorie diet as the fuel reserves required are much higher, so that was a real slog! I coped, but I knew that it really wouldn’t be a good idea for someone who trains using long duration cardio such as running or cycling.

Behavioural effects of a 1000 Calorie Diet

This is perhaps the most interesting area to me lately. Following on from my recent no sugar experiment, I’ve become more interested in the behavioural choices we make around food, because essentially it’s just a series of decisions we make each time we come to eat.

When following the 1000 calorie diet, I was forced into making different choices. Anyone who is familiar with macronutrients will be aware that when dieting, it is still important to maintain a high protein intake, especially if you are active. With this in mind, I had to ensure my food options were (relatively) high in protein yet low in calories. This isn’t easy.

Next up was a volume issue – I had to ensure that I was eating enough to feel as though I actually had something in my stomach. There are tricks to this, such as making sure you drink plenty of water so you stay full etc, but it’s still something you have to consider.

Flavour is key too. If you are already eating low calorie, you have to have a least some enjoyment from your food, so I found myself opting for things that at least tasted good! It opened me to a few new options I’d never have really considered before, such as vegetarian curry snack packs – they averaged around 200 calories but contained a lot more food than the meat versions, ticking the volume box!

Uses for a 1000 calorie diet

My initial thoughts are that it’s idea for anyone looking to kick start weight loss. Most people wouldn’t cope on it for the long term, but as a short term fix it certainly has its uses. I dropped over 8lbs in 5 days using it.

I also think it’s a great behaviour change tool. If you respond well to strict rules around your diet, sticking to 1000 calories is a simple but easy enough one to follow. You don’t have to count macros or follow meal timing rules, you just eat 1000 calories and try to keep your protein high. A high protein intake is important, whether you go for whole food sources, bars, shakes or even BCAA drinks.

Who shouldn’t follow a 1000 calorie diet

If you are a competing athlete with a high training volume, then the 1000 calorie diet isn’t for you. It’s basically impossible to maintain a high training volume on such a low intake of energy.

Cardio bunnies would also struggle. By nature of their exercise, anyone who is running, cycling or swimming multiple times per week would really struggle with the 1000 calorie diet.

Manipulating the 1000 calorie diet for the long term

I have given this some thought and think manipulating a 1000 calorie diet for long term use is both possible and practical for anyone looking to lose weight or body fat.

The diet would look like a modified 5:2, with the daily base line calories being 1000, from high protein sources. On training days, calories would be spiked relative to the activity and the rate of weight loss, but would revert to the 1000 calories on non-training days.

The diet would have to be individually tailored, but I think that approach would work. I can’t think of a reason it wouldn’t, but I’ll spend more time on my thinking/experimenting around the topic before I use it as a tool or suggestion for personal training clients.

Training and a 1000 calorie diet

When you’re trying to sustain yourself on a 1000 calorie diet, you can still train but the type of training that you do needs to fall in line. If you’re expecting to run marathons or cycle for 50 miles on such small amounts of food, you’re going to find it impossible.

If you go for lower intensity weight training, like light weight leg pressing, chest pressing etc, you’ll cope easily even on the low calories.

What you need to do instead is focus on short, sharp bursts of effort. Weight lifting, weight training and some HIIT protocols will work. The kind of workouts I was doing on my 1000 calorie diet are the ones in my HIIT eBook.

I did some of these workouts on 4 of the 5 days I was eating the 1000 calorie diet and found them to be tough, but I could cope. It’s because the nature of the workouts are that they are short, but intense – perfect for when you’re only eating 1000 calories per day!

The 1000 calorie diet, final thoughts

The first conclusion to draw regarding the 1000 calorie diet is that yes, it’s totally possible to live on 1000 calories. There are performance issues, but if you have weight/body fat to lose, it’s very much an approach that can work for you.

I safeguarded by dramatically increasing my micronutrient (vitamin and minerals) intake, so I felt great doing it.

A lot of our behaviour around food is purely habitual, so forcing a dramatic change in your behaviour around food makes you really think about the choices you make.

As a long term dietary approach, it’d need some manipulation in order for it to be a suitable long term option, but I honestly think with a level of self-control and discipline, it’s something that could work for most people. As long you ramped-up calories around activity, it’s a diet that would prove very effective for many.

UPDATE! In Feb 2020 I did a 3 Day Fast – it’s part of the ongoing experimentation in my nutrition. It was a really interesting experiment and I learned so much and experienced things I’d heard about first-hand. I blogged about it here. Take a look, because I’ve no doubt you’ll learn a few things.

Pros, Cons, and How It Works

At Verywell, we believe there is no one-size-fits-all approach to a healthy lifestyle. Successful eating plans need to be individualized and take the whole person into consideration. Prior to starting a new diet plan, consult with your healthcare provider or a registered dietitian, especially if you have an underlying health condition.

A very low-calorie diet (VLCD) is a rapid weight-loss program in which calories are severely restricted. It was developed in the 1970s for patients whose body mass index (BMI) is 30 or higher—people who need to lose weight quickly because of the health consequences of their obesity. VLCDs are often used to help obese patients achieve significant, short-term weight loss as part of a comprehensive weight-loss program. Because food intake is so limited and calories are restricted to about 800 a day, very low-calorie diets should only be followed in certain cases and must be supervised by a doctor.

VLC diets are not normally used for patients with a BMI between 27 and 30 unless they have medical conditions related to their weight, such as diabetes or high blood pressure. Very low-calorie diets are not usually prescribed for children or teens. They are also not usually considered appropriate for older people due to potential side effects, pre-existing medical conditions, and/or medication needs. Your physician will decide whether or not a very low-calorie diet is appropriate for you.

What Experts Say

“A very low-calorie diet is a medically supervised plan eliciting rapid weight loss in those with a high BMI. Because patients eat 800 calories or less per day, it should only be done under a doctor’s supervision and paired with specialty foods to prevent nutrient deficiencies.”
—Chrissy Carroll, RD, MPH

What Can You Eat?

In most cases, liquid protein shakes or meal-replacement bars are taken in place of food for a period of time, ranging from several weeks to several months. However, some very low-calorie diet plans include lean proteins, such as fish and chicken, or only eat one type of food (such as the mono-diet).

What You Need to Know

Very low-calorie diets are designed to produce rapid weight loss at the beginning of a weight-loss program. An obese patient can expect to lose about 3 to 5 pounds per week while following a very low-calorie diet. The average weight loss for a 12-week VLCD is about 44 pounds. This amount of weight loss can significantly improve obesity-related medical conditions, such as diabetes, high blood pressure, and high cholesterol.

Within three to six months, a patient may be able to lose about 15 percent to 25 percent of their initial weight if they start with a very low-calorie diet and transition to a healthy lifestyle, a calorie-controlled eating plan, and an exercise program.

Research has shown the long-term results of VLC diets vary significantly. Weight regain is common. Combining a VLC diet with behavior therapy, exercise, and follow-up treatment may prevent this. VLC participants typically maintain a 5-percent weight loss after two years if they adopt a healthy eating and exercise plan.

Your doctor-prescribed very low-calorie diet may come with suggestions for when during the day to consume your meal replacements and when to consume any food you might be eating outside of the replacement items (if any; often, you do not consume anything other than the prescribed foods).

The bars and shakes used in a VLCD are not the same as diet products at the grocery store. Rather, meal replacements are specially formulated to contain adequate vitamins and nutrients, so patients’ nutritional requirements are met.

Pros and Cons



Doctors often prescribe very low-calorie diets when other eating plans and weight-loss attempts have failed. Studies show that these diets often work well, at least in the short term. But they need to be followed carefully and have a behavior component that teaches patients how to change their eating habits for the long term.

General Nutrition

Because the meal replacements in very low-calorie diets are specially prepared for this purpose, they help patients get the essential nutrients they are not otherwise getting from food. This is why medical supervision is essential to the safety of a VLCD.

These positives do not necessarily mean a very low-calorie diet is right for everyone. It can be a good choice for specific people and situations.


Side Effects

Many patients who follow a very low-calorie diet for four to 16 weeks experience side effects such as fatigue, constipation, nausea, or diarrhea. These symptoms usually improve within a few weeks and rarely prevent patients from completing the program. The most common, serious side effect of a very low-calorie diet is gallstones.

Medical Supervision

To safely follow a very low-calorie diet, you must have a prescription and be monitored by a physician, which will require time and money. Typically, health insurance does not cover the cost of the meal replacements (of course, you will not be buying any groceries or restaurant meals during the VLCD).


A very low-calorie diet is a short-term solution for weight loss. It is meant to be followed for a limited time. After that, patients will need to transition to a maintenance plan that includes healthy eating, exercise, and other lifestyle changes.

Is a Very Low-Calorie Diet Right For You?

Very low-calorie diets are unique in that they are medically supervised, and they eliminate all foods except for specially formulated meal replacements. Some other diets take aspects of the VLCD and modify it for more general use.

The USDA recommends a diet of about 2000 calories (this can vary based on age, sex, weight, and activity level) for weight maintenance and reducing your calories depending on individual health and lifestyle factors for weight loss. The VLCD reduces this severely, down to 800 calories or less, which is why it must be overseen by a doctor.

Health Benefits

Body Composition

A greater rate of weight loss in a shorter period can result in better physical improvements, including fat loss, waist circumference, the relative amount of lean mass compared to body fat, nutritional status, and walking stride.

Reduced Side Effects of Some Conditions

VLCD can also improve symptoms in patients with diabetes, psoriasis, osteoarthritis, and obstructive sleep apnea.

Prepare for Surgery

VLCD can help people with obesity lose enough weight to prepare them for bariatric surgery.

Health Risks

Low Calcium

The nature of VLCD means that it can be more difficult to obtain enough nutrients. One negative result of VLCD is the potential for bone density loss due to low calcium levels.

Adverse Side Effects

VLCD can cause side effects such as headaches, weakness, fatigue, nausea and vomiting, constipation, dehydration, low blood sugar, bad breath, diarrhea, and dizziness.


Gallstones often develop in people who are obese, especially in women. They are even more common during rapid weight loss. Your healthcare provider may be able to prescribe medication to prevent gallstone formation during rapid weight loss.

Hair Loss

Hair loss is a potential long-term side effect of VLCD.

A Word From Verywell

Many dieters who go on very low-calorie diets rebound and binge eat when they get too hungry. It is possible to regain any weight you lose and even put on extra weight as a result. For these reasons, it’s generally not a good idea to follow diets or weight-loss programs that provide only 900 calories a day or less. You’ll see many plans advertised in magazines and online, some with healthy claims attached to them. But without proper nutrition, you are likely to get tired and develop or exacerbate health problems.

A doctor-supervised very low-calorie diet can offer that nutrition, at least, although it is likely to be tough work to stick with. Still, in certain cases, a doctor may recommend a VLCD as the best way to lose weight in the short term. It will need to be followed up with behavioral changes and a healthy lifestyle.

Will Eating 1000 Calories a Day Cause Weight Loss?

Make quality food — not calories — the focus of your meals.

A low-calorie diet definitely induces weight loss, but lowering your calories too much can actually hamper your results. In cases where extreme obesity causes medical complications, a 1,000-calorie diet may be prescribed to initiate quick weight loss. But trying such a diet on your own puts you at risk of developing nutritional deficiencies, stalling your metabolism and losing valuable muscle mass. Reduce your calorie intake to a healthy level for your body, and add exercise to lose weight gradually.

Fast Weight Loss Is Unsustainable

Although it’s recommended that you create a calorie deficit of 500 to 1,000 calories a day to lose 1 to 2 pounds a week, this rate may be too aggressive for some people. If achieving that rate requires extreme deprivation, it’s unlikely you can stick to the plan.

Diets that dip below 1,200 calories per day are extremely difficult to adhere to for any length of time, because essentially — you’re starving your body. You may lose weight quickly on a 1,000-calorie diet, but the lost weight is mostly water and lean mass — not fat. It’s nearly impossible for you to get all the vitamins and minerals you need — even at 1,200 calories per day — especially if you’re a woman of child-bearing age.

When you follow a 1,000-calorie plan, any weight you do lose will likely return fairly quickly, once you resume eating a normal meal plan. Your lingering hunger from such a restrictive plan could even cause you to compensate by overeating, which could contribute to gaining the weight back.

Healthier Options

Low-calorie diets are recommended as a way to lose weight, because they help you create a deficit between the calories you burn and those you take in. When your body uses more energy in the form of calories than it takes in, fat is lost. Trimming caloric intake isn’t the only way to create this deficit. Consider upping the amount of energy you use daily through physical activity and daily function — like fidgeting and walking — to lose weight. The American College of Sports Medicine advocates 250 minutes per week of moderate-intensity cardiovascular activity to spur significant weight loss.

A diet containing between 1,200 and 1,400 calories is still considered low calorie, and will prompt weight loss in most people — even in sedentary women. Men, because of their larger size and subsequently greater energy needs, might require approximately 1,800 calories per day to lose weight safely and to keep it off.

The Quality of Calories Matter

Choosing quality foods that offer optimal nutrition and satiation when you’re trying to drop pounds is critical. Fill your plate with lots of nutrient-dense but calorie-light, green, watery vegetables. Lean protein helps you feel full, so choose skinless chicken or turkey, lean beef, fish or eggs at most meals. Also include whole grains because they contain fiber — which takes longer to digest — and avoid refined grains such as white bread. Processed foods manage to pack a lot of calories into small servings, so avoid them. If you need a low-calorie snack — opt for a piece of fresh fruit or low-fat, plain yogurt with berries.

Sometimes, people on a 1,200-calorie-per-day diet don’t lose weight and think they need to trim their intake more to get results. Chances are, they’re underestimating their daily caloric intake. They may simply forget about a snack they ate, get so hungry that they then eat a larger serving than they had planned or they don’t measure and weigh their food to make sure they’re on track. If you’ve hit a weight loss plateau on a 1,200-calorie diet, make sure you weigh your portions, and try writing down everything you eat so that you don’t forget a food item or two.

The Medical Need for 1,000 Calories Per Day

When your weight seriously endangers your health or you’re prepping for an intense obesity treatment, such as bariatric surgery, your doctor may prescribe a very low-calorie diet of 800 calories or a low-calorie diet of 1,000 calories a day. This calorie limit is usually prescribed to women, as it’s considered too low for most men, who are restricted to 1,200 to 1,600 calories a day on medically prescribed low-calorie plans. In such cases, the 1,000-calorie diet is designed by a dietitian and usually consists of small portions of whole foods, but it may include meal replacements to help you get all the requisite vitamins, minerals and fiber you need.

Very low calorie diets – NHS

A very low calorie diet is a clinically supervised diet plan that involves eating about 800 calories a day or fewer. They are sometimes considered for obese and severely obese people who are managing diabetes, going to have surgery or preparing for fertility treatment.

The diet usually involves replacing normal food with low-calorie shakes, soups, bars, or porridge containing milk.

Very low calorie diets are for adults who are obese and severely obese, defined as having a BMI over 30 and 40, and need to quickly lose weight. They are not the first option to manage obesity and should not be routinely used.

Very low calorie diets should only be followed under medical supervision for a maximum of 12 weeks. Do not follow a very low calorie diet unless a GP has suggested it to you.

Very low calorie diets are hard to follow

Very low calorie diets are less likely to be nutritionally complete as they provide far fewer calories than needed to maintain a healthy weight. The recommended daily calories are 2,500 for men and 2,000 for women.

It is not an easy diet to follow. Side effects can include:

  • feeling hungry
  • feeling low on energy
  • a dry mouth
  • constipation or diarrhoea
  • headaches
  • dizziness
  • cramps
  • hair thinning

While very low calorie diets can lead to short term weight loss, it is likely that the weight will come back on after the diet ends.

Very low calorie diets are not a long-term weight management strategy and should only be used as part of a wider plan.

Very low calorie diets are not suitable for most people

See a GP if you think a very low calorie diet may benefit you.

Read about eating a balanced diet

If a GP thinks a very low calorie diet might benefit you they should make sure:

  • the diet is nutritionally complete
  • the diet is followed for a maximum of 12 weeks (continuously or intermittently)
  • you are given ongoing support after the diet

Very low calorie diets are the most restrictive form of dieting, severely reducing calorie intake, so medical supervision is important.

As always, the article is not so interesting, but the comments to it, where everyone partly agrees with the author “yes, it’s obvious, to lose weight, you need to eat less”, adds something from his bell tower “but how can you lose weight if you have bad hormones / slow metabolism / cravings for sweets / “, etc.d.

I train online and one of my clients’ frequent requests is weight loss. I am not a nutritionist, and I do not compose a diet for people with gastrointestinal diseases and so on. I am not a nutritionist, and I do not formulate micronutrient rations to make up for deficiencies, etc. I am a trainer and I motivate (force) the trainees to train under my control until it becomes a stable habit, and so that the training is not accompanied by a loss of strength, injuries, underrecovery, I help to adjust nutrition.And bright results in training are possible only with a properly selected diet. When all these conditions are met, my ward will inevitably lose weight, even when such a task was not set.

So the accumulated experience allows us to speculate in this direction and disassemble the frequent misconceptions about the process of weight loss, which once again met in the comments.

Why do we lose weight / gain weight?

Introductory point. Because we are upsetting the energy balance.

The body is an open system and it obeys the laws of thermodynamics.Energy in an open system cannot arise and disappear into nowhere. If the energy supplied to the system exceeds the flow rate, it will not disappear anywhere, but will remain in the system.

If we eat more than spent, energy is stored in reserves.

The theory lends itself to the principles of determinism – by the amount of carbon dioxide, water and heat released, you can determine how much a person has spent energy in a period of time.

And all this works so well that by creating a calorie deficit, you can calculate the approximate speed and timing of weight loss. Why approximately?

There are two variables in the weight loss formula – the energy received and the energy consumed.But you and I are not metal, and not water, which can only be in three states. We are a living organism that goes through hundreds of conditions every day, they affect the functions of systems, organs, which directly affects both the amount of energy received (appetite) and the level of consumption (laziness, fatigue …). Almost like in a car – knowing the volume of the engine , the weight of the car and the amount of gasoline in the tank, you can determine how many km the car will travel. But there are many variables that affect the final consumption: headwind, tailwind, road quality, number of passengers, urban conditions or a straight line, some breakdowns.Of these variables, we have mood, memory (we forget the amount of food), hormone activity, physical activity, the number of muscles – all this affects both the expenditure and consumption of energy, each in a different degree and at different periods of time.

But one thing remains basic – how much you fill up, so much you go. And the more variable data you have, the more accurately you can determine the flow rate.How much you eat, about the same amount you are active, and knowing the additional variables, you can more accurately determine the speed and duration of weight loss. So scientists in clinical studies, under constant observation of the subject, measuring the heart rate, depth of inhalation and exhalation, blinking frequency, the amount and composition of exhaled air, determine the energy consumption of an individual very, very accurately.

one.”What helps one does not help another”

It was quite rightly noticed by the commentator. But it’s important to put this recommendation in context, so I’m rephrasing that what helps one maintain a consistent diet and calorie deficit is unlikely to help another.

Because of this, we hear different things.For some, only rejection of sugar and fast carbohydrates works, for others “I tried everything, but only rejection of fats helped,” still others drown for sports, others profess a stoned healthy lifestyle or “eat everything and count calories”.

Everyone is individual, but this does not mean that one has the law of conservation of energy, while the other does not, and only the amount of insulin released affects his obesity.The law works for everyone. In losing weight, consistency is important – i.e. the ability to maintain a deficit for a long time (4 months or more), smoothly changing dietary habits, because short-term hunger strikes and changing the diet just to lose weight will still lead to weight rollback.

We are individual in our ability to maintain this consistency.

Since in the matter of losing weight, the ability to control hunger plays an important role, the keto diet helps someone to pacify the rumbling in the stomach, someone intermittent fasting, someone PP, and so on. But in my experience, mindful eating is the best method. Those. when you are familiar with what you eat. You understand well how many BJUs are in a plate and what each of these letters gives to your body.You understand something about micronutrients. You learn to make the correct proportions of KBZhU from those products that are already accustomed to eating . If the basket is completely melancholy and continuous refined sugar, then it is very smooth to add new positions, to begin with within the framework of the experiment, then permanently.

The presence or absence of sports affects the psychological comfort of compliance with the new conditions, and they affect the success of the diet in general.But if the sport does not work at all, then it is better to postpone it.

It is important to understand in which mode you can achieve the best consistency.

2. Calorie deficit only works in healthy people.

It may seem so, but it works for everyone.

As I wrote, there are many variables that affect the rate of weight loss. If we summarize these variables, then the thinners can be divided into several large groups:

  • Obese or normal weight.
  • Paul.
  • Metabolic disorders or lack thereof.
  • Hormonal disorders or their absence.
  • Low activity level, medium, high.
  • Reaction to a calorie deficit or lack thereof.
  • Honesty.
  • Psychological stability.

Something you can know in advance and immediately apply tools suitable for this type.For example, low-carb diets ( keto or LCHF ) are well suited for people with insulin resistance. The severity of recommendations depends on the level of obesity – if the degree of obesity is 2 or higher, you can make a very strict deficit of up to 50% of the daily requirement, because being overweight is more harmful than discomfort in the diet. So it is with sports – people with metabolic disorders are extremely important to exercise with weights, and then they will not care if they like it or not.You can also knock on the head of the trainer for skipping a workout, and remind once again about the negative effects of fat ballast. And if a person is of normal body weight, but wants to dry out, then the approach is completely different – the key to success will be the search for a passing course and creating comfortable conditions in the diet, regimen, training.

Something cannot be predicted in advance, for example the last 3 points.

I have had people who, from an optimist, fell into a state close to depression within two weeks, even due to a small calorie deficit and a completely balanced diet. Rigidity like “come on, bag, drag your body to training” to such people can repel them for a long time from the desire to get in shape. And there are those who are depressed in life and come to train like that – with them the “Major Payne” regimen does not work very badly.

The deficit works for EVERYONE. But each of us has our own set of variables that will affect the success and rate of weight loss.

3. “Excess weight in the head.”

No matter how thin, the trauma from childhood will still force you to gnaw off a sausage – also a common parable of unsuccessful thinners.I am not denying the problem as a whole. I mean, most likely, this applies to a very small number of people with real diagnoses. Otherwise, “ Craving for sweets, this sweet was forbidden to me in childhood” , “ Craving for fatty” , “ I can’t lose weight, probably a problem from my childhood makes me eat” , “ I’m afraid to be slim, Caucasians will steal “- the client really had such fear. But most cravings and inability to control appetite are consequences of a diet and lifestyle curve.

There are 3 pillars that affect our ability to control appetite and even make healthy choices: sleep (its quantity and quality), level of physical activity , alcohol , or rather lack of it. It just so happens that at least one point follows everyone. Many collect everything 3. Some research.

2. The higher the activity, the more food you can afford to eat without getting fat. The stomach will fill up more, which means that satiety will be kept longer. Here many will give an example that the stomach will stretch and will still ask for food, but no. Fortunately, it doesn’t work that way.Surprisingly, an increase in activity leads to an increase in consumption, but a decrease in activity does not lead to a decrease in consumption. So if you move less, you will not eat less. The lower the activity, the poorer appetite control, more overeating and weight gain. Activity also affects the quality of sleep – the higher, the better you sleep.

3.Alcohol increases your cravings for fatty and salty foods. Fat is the most nutritious nutrient, 9 kcal. for 1 gr. The combination of fat + salt (burger, fries, pizza) is the most powerful and desirable texture and flavor combination for the tongue and the brain (I can’t find a link to this study right away). Regular alcohol consumption will only increase the cravings, which are likely already formed due to low activity and lack of sleep.

Someone else may mention stress, but sleep and exercise relieve it well, so this is rather a consequence.

As you can see, the lifestyle creates problems with weight, and prevents you from getting rid of these problems. Try to fix the points above first before going to a psychotherapist to treat cravings. This will give a bonus not only for body composition, but also for the quality of life in general.

four.”Losing weight is not useful.”

If the degree of obesity is 2 or higher, it is very useful. Fat people can make a severe deficit, fat people can easily keep it due to the abundance of stored energy. They may even give a damn about the proportions of BJU, because they almost never lose muscle when losing weight. They can score in general on the quality of food, because being overweight is a greater health hazard than an unbalanced diet. But it is still worth doing high-quality work with the diet and habits, because the task is not only to lose weight, but also not to gain back, and the right eating habits will help with this.

Those who are of normal body weight do not need to lose weight. Girls often have problems with the cycle, trying to lose weight. When losing weight from normal weight to dry weight, a lot of muscle is lost, hormones are disturbed.

As a rule, weight loss is accompanied by a low protein intake, from which combing out a clump of hair with a comb will become a daily routine. The skin will lose its tone, brittle nails, poor health. Men lose libido, especially when they do not monitor the amount and variety of fats in the diet. In general, if you do badly, then of course it is harmful. If wisely, then the consequences are minimal.

For those who are not overweight, it will be more important to monitor the amount of muscle mass, because today such a disease as metabolic obesity appears more and more often in the literature. This is when the body weight is normal, but the muscles are very small. Such proportions give diagnoses in the outpatient card as a carbon copy from a fat man – high blood pressure, poor insulin sensitivity, glucose above normal, poor sleep, snoring, dizziness, and so on.

It is more important not to be thin, but to have a lot of muscles. For this you need to train.

5. “Most fat people eat the same amount as everyone else.”

There are two variables in the weight loss formula.You can eat as much, but move ugly little.

The fuller a person is, the less he moves, because it causes discomfort, thereby further accelerating the weight gain, despite the fact that he did not eat more.

6.”My thin friend eats as if not to himself, and the other pecks bread crumbs and a fat one.”

From experience: if you take control of each of these individuals, it turns out that the first eats a lot only with you. The rest of the time he will forget, get distracted, eat a cucumber, interrupt himself with a cup of coffee and, in general, move a lot. And the second copy eats little only according to statements. Fat people are often embarrassed to eat in front of others, this may give the impression that they always eat little.Overweight people often forget what they ate. Knowingly or unknowingly, they lie about the amount of food. Even if they keep a food diary and know that they will be checking it, they indicate an underestimated number of calories. A study in which 9 out of 10 girls lied in their reports, although they were trained and told that everything would be checked.

In general, fat men tend to underestimate the calorie content of the diet, while thin ones overestimate.

As you can see, losing weight is a minefield. Plus if you can shed more light on this topic.

90,000 Nutrition in Numbers: All About Daily Values ​​| Food

Intuitive nutrition or total control over the diet? In both cases, it will not be superfluous to find out how close your relationship with food is to what is considered to be “normal” – in terms of calorie content, BJU balance, the amount of vegetables, fruits, liquid and other indicators.

Caloric content of the diet

Like other nutritional norms, this one is relative, and depends largely on such parameters as height and weight, age and gender, and the degree of activity.

If we talk about the average, then in adult men the daily energy requirement varies from 2100 to 4200 kcal, and in women – from 1800 to 3050 kcal. The spread is large; to get a more accurate understanding, it is advised to use the Mifflin-Geor formula (you need to take into account, however, that it is also intended for average people).It, unlike another popular Harris-Benedict formula, first derived in 1919, is more modern – it takes into account how people’s lifestyles have changed over several decades. Thanks to her, you can calculate your metabolic level, understand the basic energy expenditure.


5 + (10 × weight in kg) + (6.25 × height in cm) – (5 × age) = BMR (basal metabolic rate)


( 10 × weight in kg) + (6.25 × height in cm) – (5 × age) – 161 = BMR (basal metabolic rate)

There is also a formula for quick calculations: this is 23 x weight in kg for women and 24 x weight in kg for men.

The calculations do not end there. Next, you should multiply the resulting number by the activity coefficient, which each has its own.

  • 1.4 – sedentary, sedentary lifestyle, in which there is almost no place for sports;
  • 1.6 – the same low activity, but with training, albeit rare (1-2 times a week)
  • 1.8 – this coefficient refers to people who work “on their feet” and because of this more mobile;
  • 2.0 and more – numbers associated with hard physical work.

The coefficient you have chosen should be increased by 0.3 – if you are actively involved in sports on a regular basis, from 3 to 5 times a week.

The result will be about the number of calories you should get from food if you want to stay in your weight. Those who expect to lose weight, as you know, need to consume calories in excess of their consumption. It is considered optimal to reduce the calorie content of your diet by about 500 kcal if your task is to lose weight.The resulting number, however, should not be less than 1200 after such a deduction. According to nutritionists, with such a low calorie diet, there is a risk that the body will not receive all the substances it needs for health. Plus, with such a lack of calories, you can lose about 500 g of fat per week per week; just up to 500 g is a safe amount that will not affect health.


Proteins, fats and carbohydrates are called so because they are required by the body in large quantities (these are tens and hundreds of grams).The daily norms will again differ depending on gender, age, lifestyle and other indicators.

For normal body functioning, according to experts from our country, adult women need from 58 to 87 g of protein per day, while men – from 65 to 117 g. On average, we are talking about 1.2-1.5 g of protein per kilogram of dry (!) body weight. The numbers, again, fluctuate, and scientists argue among themselves; Thus, at the “Protein Summit 2.0” in Washington in 2013, it was decided that even 1.6 g per kilogram of weight could be considered the norm.With active sports, this amount can be increased up to 2 g per kilogram of weight. Saturating your diet with protein, you should know that it is good not only as a “building material” for muscles. Those who are losing weight can also lean on protein, since it is difficult for the body to convert protein into fat deposits, which cannot be said about carbohydrates.

Concerning fats, the opinion is also controversial. Some sources claim that the daily allowance for women who want to maintain weight and healthy body function is from 45 to 55 g, depending on weight, while men are allowed up to 65 g of fat.Others argue that you need to multiply your body weight by 0.8-1 to get your daily value. But here it is more important to understand that 1 g of fat is 9 kcal, the proportion of fat in the total caloric content of the diet should be approximately 20-30% – but at the same time, it should not fall below 20. Fats are essential for many metabolic processes, including the absorption of vitamins and the production of hormones. Therefore, their deficiency can affect health.

As for carbohydrates, they are normally required the most: to find out “your” amount, multiplying your body weight by 3 will help you.Those who are actively involved in sports and literally testing their body for strength need 5-6 g per kilogram of weight. It is best to keep most of this complex carbohydrates so that there are no “empty” calories in your diet that do not provide any benefit to the body.

Separately, it should be said about fiber: it is believed that adults need 20-30 g, about 14 or 15 g for every 1000 kcal.

Thinking over the ratio of proteins, fats and carbohydrates, it should be remembered that in fats, as already mentioned, 9 kcal, in proteins and carbohydrates – 4 kcal each.The optimal ratio of these nutrients for maintaining weight is considered to be 30/20/50, while those who want to maintain weight and improve their figure in terms of relief can use the 40/20/40 scheme.

Vegetables and fruits

Opinions differ regarding these products, not only because the rate must, again, be calculated individually. The scientists themselves, who are investigating the issue, do not agree with each other in the derived formulas. For example, the WHO recommends at least 400 g of fruits and vegetables for daily consumption (by the way, potatoes are not included in this norm), dividing this amount into 5 servings.At the same time, variety is important, and the rainbow principle will help with it: choose fruits and vegetables of different colors, planning your diet for the day. By the way, dried fruits are also included in the designated number, but it would be good to have a single portion no more than 30 g. Those that are adopted within individual countries differ from the WHO standards. For example, in Russia, the rational rate of consumption of fresh fruits and vegetables per day is considered to be about 650 g (based on the fact that the Ministry of Health advises to consume 140 kg of vegetables and 100 kg of fruits per year).


According to experts, you need about 1.5-2 liters of liquid per day.It is not necessary that it was only pure drinking water, but it is better to strive for it to be the basis of this amount. To calculate the rate individually for yourself, multiply your recommended weight (women need to subtract 110 from your height in cm, men – 100) by 30. To find out your rate for those days when you are actively involved in sports, multiply by 40.

    Healthy Weight Loss »Health Center

    There are no magic diets, pills or operations for long-term, healthy weight loss

    The right approach is to choose the diet that is optimal for you.This is a meal plan that you can live with.

    What you should know about losing weight

    3500 calories correspond to 1 pound (0.45 kg) body weight. This means that if you decrease (or increase) your daily calorie intake by 500, you will lose (or gain) 1 pound per week. (500 calories per day x 7 days = 3500 calories.)

    All foods contain carbohydrates, proteins and fats. There are 4 calories in a gram of carbohydrates. There are 4 calories per gram of protein. There are 9 calories per gram of fat.

    Carbohydrates can be simple or complex. Simple carbohydrates lead to faster weight gain than complex carbohydrates. Simple carbohydrates include sugar and starch (potatoes, pasta, and rice). Complex carbohydrates include fruits, vegetables, and whole grains.

    What you can do to lose weight

    Determine your starting point. Keep a food diary for 3-5 days. During this period, eat in your usual way. Write down everything you eat or drink. Measure portions of non-labeled foods.For each food, determine the total calories and weight of carbohydrates, proteins and fats in grams. (You can find this information in books on calorie counting, smartphone apps, or computer programs. The Nutrient Database is located at ndb.nal.usda.gov/ndb/foods). Record total calories and grams of carbohydrates, proteins, and fats for each food item.

    Identify the problem. Analyze your daily calorie intake. If you are gaining weight, you are consuming too many calories.If your body weight is stable, the amount of calories you consume is spent on maintaining weight. But to lose weight, you need to reduce your calorie intake.

    Correct the problem. Avoid (or limit) foods with “empty” calories. These foods do not contain enough essential nutrients. Examples include sodas, alcoholic beverages, and sweets.

    Determine an achievable calorie goal.Start by reducing your daily calorie intake by 500-1000. Within this range, adjust your calorie intake so that you lose 1 to 2 pounds (approximately 0.5 to 1.0 kg) each week. If you feel good after 1–2 weeks and want to lose weight faster, you can reduce your calorie intake even further. Do not consume less than 1000 calories per day without medical supervision. Some people can lose weight by consuming 3,000 calories per day. Others will need to cut their intake to 1,100 calories per day.

    There is no optimal ratio of carbohydrates, proteins and fats for weight loss. However, most medical professionals recommend a balanced diet containing approximately 15% to 20% of calories from protein, 20% to 35% of calories from fat, and the rest of the calories from complex carbohydrates.

    You should consume enough protein. Women of average weight require 50-60 grams per day. Men of average weight require 65-75 grams per day.If you are larger, exercise, or sick, your protein requirement may be much higher. If you are hungry after a meal, eat more protein. If you eat only small portions of salad throughout the day, your metabolism will slow down. This will get in the way if you want to lose weight.

    The following are some typical protein values ​​for common foods: 3 ounces (85 g) lean meat = 25 grams of protein; 3 ounces of fish = 20 grams; 8 ounces (227 grams) milk = 8 grams 1 ounce (28 grams) cheese = 7 grams 1 egg = 6 grams.

    Snack on vegetables and fruits. For example, eat baby carrots or celery stalks with salsa instead of chips. Eat berries instead of chocolate chips. Eat apples instead of apple pie.

    Helpful hints and tips

    To lose weight, you need to change your habits. This is a long process. Losing 1 or 2 pounds in a week is great.

    Your goal should be to improve your health and well-being. If you have serious health problems, see your doctor.Such problems include type 2 diabetes, heart disease, or kidney disease. If you take


    medications, consult your doctor, as you will have to adjust the doses if you lose weight. This is especially important if you have diabetes or high blood pressure.

    Choose an active activity to your liking and move towards your goal. For example, start walking or hiking. Sign up for tai chi or tap dance classes. Join a bowling or basketball team.

    Exercise will strengthen your muscles and help slow skin sagging. In addition, exercise increases muscle growth. This will increase the number of calories your body burns daily. Aim for at least 30 minutes of exercise a day. Walking, even at a slow pace, for 10 minutes, gives excellent results. Pedometers (step counters) allow you to track the distance covered. It will also motivate you.

    90,000 short description, menu for the week

    What kind of diets have not been invented today.Apple, kefir, meat and chocolate, strict and loyal. At the same time, the number of those who want to lose weight does not decrease. Either diets work poorly, or willpower is lame. If you’re okay with the latter, try the 1000 calorie diet. It is strict, maybe even unnecessary, but if you adhere to such a diet, then you will not have a chance not to lose weight.

    Most of us are not used to stopping at our goals. But the desire to wear size 44 instead of 52, and not sometime, but after a few months, sometimes borders on insanity.A prime example is the 1000 calorie diet. Most of us consume about 2000 kcal per day, and such a sharp decrease in calorie intake is not able to pass without leaving a trace for your health. Even if you haven’t complained about it so far.

    What you need to know about

    If until now you have not denied yourself anything, then such a sharp restriction in food will become severe stress for the strongest organism. This method can be used if you urgently need to get rid of 3-4 kg in a few days.A strict mono-diet that excludes the normal daily intake of proteins, fats and carbohydrates should not last more than 2 weeks. And even this period is dangerous. Best of all, it will be limited to 5-7 days. Otherwise, hormonal changes will begin in the body, the consequence of which is metabolic disorders and a slowdown in metabolic processes. The 1,000 calorie diet is a classic example.

    Forewarned means armed

    The processes of losing weight have been studied for a long time. And scientists were able to establish that a person who has never been on a diet does not gain as much kilogram as chronically “losing weight”.If you decide to choose a 1000 calorie diet, then you need to consider this fact. Let’s take a look at the mechanism that leads to this phenomenon.

    If the calorie restriction continues for more than a week, then the body perceives this as the onset of hunger times. As a result, the most severe economy mode is activated. Metabolism slows down, and protein compounds from muscle tissue are used as an energy source. This is accompanied by fluid loss and weight loss. At the same time, the body retains fat until the very end, as a guarantee of survival.

    Hormonal changes are easy to start, but then it can be extremely difficult to return the state to normal. Uncontrolled processes may begin, which will adversely affect the functioning of all organs and systems. A 1000 calorie per day diet can only be considered a short-term diet so as not to do too much harm.


    Usually, when a person decides to go on a diet, he dreams of new forms. Dreaming of what it will look like, he forgets that free cheese is only in a mousetrap.This rule also works here. Thanks to the low calorie diet, you begin to lose weight quickly. This leads to the fact that the skin loses its elasticity, the figure becomes shapeless. Under the condition of physical exertion, everything will gradually recover, but this takes time. But this is not the worst thing.

    As a result of an improper diet, the risk of getting fat even more after the end of the diet increases significantly. Therefore, you need to carefully study the menu of the 1000 calorie diet and decide whether the result is worth such consequences.Often, after mono-diets, people noted a loss of the ability to think clearly and concentrate.

    There is one more effect that you should be aware of. After the diet is over, you move on to your regular diet and the body starts storing fat again. This happens on the condition that you spend less than you consume. So, the fat that is formed in a person who either sits on a strict diet or eats normally is very different. It is now deposited not under the skin, but in the abdominal cavity and around the internal organs.It readily seeps into the bloodstream and liver, which can cause serious illnesses such as heart attacks or strokes.

    What you can eat per 1000 calories per day

    The main disadvantages we have considered, now everyone can decide for himself how much this option suits him for losing weight. The 1,000 calorie diet menu can seem very sparse. In fact, if you approach this issue correctly, you can put together a good table. Another thing is that we often continue to consume high-calorie foods.For example, 100 g of Napoleon cake is already 600-800 kcal. Eating this for breakfast means leaving only the cabbage salad for the rest of the day.

    The basis of the diet should be protein products, cereals and vegetables. Their calorie content is not too high, so the portions will be sufficient in order not to experience hunger. Every day there should be stewed, boiled and fresh vegetables, cereals, lean fish and chicken fillets on the table. You can also add cottage cheese, herbs and fruits.

    What you need to exclude

    Get ready right away that it is not easy to withstand such a menu, this is underlined by numerous reviews.The 1000 calorie diet is a big test for your willpower. You will have to remove foods with a high calorie content, a large amount of fat or carbohydrates from the diet. These are:

    • Mayonnaise, sauces and ketchup.
    • Salt and sugar, all condiments and spices.
    • Flour and confectionery products.
    • Fast food.
    • Sweet carbonated drinks and alcohol.
    • Bananas and grapes.
    • Fatty, fried and smoked products.
    • Vegetables include potatoes and beets.

    Last preparation

    At first, it will be quite difficult for you to determine by eye how many calories are in a particular product. Therefore, it is recommended to purchase a kitchen scale and print yourself a table of food calories. By the end of the diet, you will already be able to determine by eye how many calories are in this cup of buckwheat or a slice of whole grain bread.

    Remove from the refrigerator anything that might be tempting. Purchase the products you need every day.This is chicken fillet, cod or pike, eggs, low-fat cottage cheese or kefir. Side dishes include green beans, broccoli and spinach, celery, cucumbers and kale. An orange or grapefruit is perfect for dessert.


    Below, consider a 1000 calorie per week diet. In the meantime, let’s focus on the rules that need to be followed:

    • The basic principle is fractional nutrition. There should be three main meals and three snacks per day.
    • The ideal breakfast will be cereals, sources of slow carbohydrates. Of course, they are also high in calories, so you should not eat more than 100 g. And to keep the feeling of fullness for a long time, add a protein source to this.
    • For lunch, lean soup with vegetable broth and separately cooked meat with salad.
    • It is best to leave fish and vegetables for dinner.

    Grain breads, fruits and nuts are suitable for a snack.

    Planning in advance

    Be sure to pre-schedule the 1000 calorie diet menu for the week.Otherwise, there will be a great temptation to eat something else. Let’s take a look at seven options for breakfast, lunch and dinner, among which you can choose the one you like best every day.

    • First breakfast. Low-fat cottage cheese – 100 g and a slice of bread and butter. Buckwheat porridge – 100 g, egg and orange. Oatmeal – 120 g with fresh berries. Two-egg omelet with asparagus beans. 100 g of cottage cheese casserole and fresh fruit. 100 g of rice and cucumber and 1 egg. Fruit salad with yogurt – 200 g.
    • Lunch or snack. This can be any fruit of your choice (2 pieces), 100 g of low-fat yogurt, a boiled egg and one carrot, a jar of yogurt and 1 fruit, a glass of carrot juice and one loaf, a glass of a banana milkshake, a rye bread with cheese.
    • Lunch. This is the main meal, so two dishes are required. A plate of vegetable soup and 120 g each of boiled meat and salad. Mushroom soup, 120 g of boiled veal and 1 tomato. Bean soup, 150 g each of broccoli and steamed fish.Boiled pasta – 100 g, 150 g of baked fish and cucumbers each. Fish soup, 150 g of stewed turkey and raw vegetable salad. Vegetable soup, 100 g of boiled chicken and green peas. Baked potatoes – 100 g, 100 g of fish and stewed vegetables.
    • Afternoon snack. It is categorically impossible to skip it. Otherwise, you will get hungry before dinner and eat too much. It can be 100 g of fruit salad, baked apple, grapefruit and a couple of nuts, 100 g of yogurt.
    • Dinner. It should be a light but nutritious meal.A couple of sardines in their own juice and 250 g of stewed vegetables. Greek salad. 100 g each of rice, chicken and radish. 200 g of meat cabbage and bell pepper. 120 g each omelet and arugula salad and 1 sardine. Braised rabbit with zucchini – 200 g. 200 g of stewed veal and vegetables.
    • A snack before bed is a glass of fat-free kefir.

    Instead of a conclusion

    This is a sample menu. The 1000 calorie diet is variable.
