Calculate Your Optimum Net Carb Intake on Keto

Whether the focus is total carbs or net carbs, counting this macronutrient is a must for many keto dieters. How else can you make sure to stay in ketosis if you’re not keeping track of how many carbs you eat in a day?

Whether the focus is total carbs or net carbs, counting this macronutrient is a must for many keto dieters. How else can you make sure to stay in ketosis if you’re not keeping track of how many carbs you eat in a day?

Do the math: how to calculate net carbs on keto

By now, you know that the keto diet is an extremely low carb, high fat diet that helps people shed pounds quickly and effectively. But as you dig deeper, you may have seen the term “net carbs” a few times. What exactly are “net carbs” and how do you calculate them? Are they different from total carbs? How many carbs am I allowed to have per day on keto? Read on to find all the answers.

Total carbs vs. Net carbs

Total carbs versus keto net carbs

For those on the keto diet, the most important thing to consider is the amount of “net carbs” in your food. This number can be quite different from the amount of total carbs, and here is why: Net carbs are the ones that are absorbed into your body. Some sources of carbohydrates like fiber and sugar alcohols are not absorbed into your bloodstream, therefore they are not part of your daily allowance of net carbs.

On the keto diet, you are allowed to have no more than 50 grams of net carbs per day – and the fewer, the better! But by focusing on “net” rather than “total” carbs, you won’t be denying your body the essential fiber it needs for proper function. Try meal planning ahead of time so you can always track how many net carbs you’re consuming.

Calculate Net Carbs

How to calculate keto net carbs

There are, of course, numerous online databases that tell you how many net carbs a food has. However, sometimes you’ll have to do it on your own. Thankfully, it’s pretty easy to do! To calculate a food’s number of net carbs, look at the label and follow these two simple steps:

1. Determine the carb content: take a look at the number of total carbohydrates, then the amount of fiber and any sugar alcohols (sometimes shown as “Erythritol” on nutrition labels). These things together equal the “total carb content.” (Any sugar shown is already included in the total carbohydrate amount).
2. Subtract the amount of dietary fiber and half the amount of sugar alcohols from the total carbohydrate amount. The result is the amount of net carbs in the food.

Take a look at the example on the side:

Net Carbs = Total Carbs – Dietary Fiber – Half Sugar Alcohols

Net Carbs = 20g – 8g – 5g = 7g

Your net carb amount will always be less than or equal to the total carb count. Remember, you can consume 50g of net carbs each day on a keto diet.

Low Net Carb Foods

What foods are low in net carbs?

Just because you now know how to calculate keto net carbs doesn’t mean you have to do so for everything you eat. There is a range of delicious, healthy foods that are positively encouraged on the keto diet.

Meats such as beef, veal, lamb, pork, chicken, and turkey, and fish such as cod, sardines, tuna, and salmon have very low net carbs. Most green and leafy vegetables also have an extremely low keto net carb count and can be enjoyed freely. And don’t forget, you can also include delicious high fiber, low fructose fruits in your keto diet plan.

5 Most Common Low Carb Mistakes (and How to Avoid Them)

Eating a lower amount of carbs per day may have metabolic benefits and support weight loss. But eating too much or not enough of certain nutrients like protein can prevent your body from reaping the benefits.

While low carb diets are very popular, it’s also easy to make mistakes on them.

There are many stumbling blocks that can lead to adverse effects and suboptimal results.

To reap all the metabolic benefits of low carb diets, merely cutting back on carbs isn’t enough.

Here are the 5 most common low carb mistakes — and how to avoid them.

While there is no strict definition of a low carb diet, anything under 100–150 grams per day is generally considered low carb. This is definitely a lot less than the amount of carbs in the standard Western diet.

You may achieve great results within this carb range, as long as you eat unprocessed whole foods.

But if you want to get into ketosis — which is essential for a ketogenic diet — then this level of intake may be too high.

Most people will need to go under 50 grams per day to reach ketosis.

Keep in mind that this doesn’t leave you with many carb options — except vegetables and small amounts of berries.

To calculate your net carbs, subtract fiber, sugar alcohols, and other nondigestible carbs from the total amount. These are the carbs to watch on a ketogenic diet.

SUMMARY

If you want to get into ketosis and reap the full metabolic benefits of low carb diets, going under 50 grams of carbs per day may be necessary.

Protein is a very important macronutrient that most people consume adequate amounts of.

It can improve feelings of fullness and increase fat burning more than other macronutrients (1).

Generally, consuming more protein should lead to weight loss and improved body composition.

However, low carb dieters who eat a lot of lean animal foods can end up eating too much protein.

When the body doesn’t have sufficient carbs, amino acids from proteins you eat will be turned into glucose via a process called gluconeogenesis (2).

This can become a problem on very low carb ketogenic diets and prevent your body from going into full ketosis.

According to some scientists, a well-formulated low carb diet should be high in fat and moderate in protein.

A good range to aim for is 0.7–0.9 grams of protein per pound (1.5–2.0 grams per kg) of body weight.

SUMMARY

Excessive protein consumption on a low carb diet can prevent you from getting into ketosis.

Most people get the majority of their calories from dietary carbs — especially sugars and grains.

When you remove this energy source from your diet, you must replace it with something else.

However, some people believe that cutting out fats on a low carb diet will make your diet even healthier. This is a big mistake.

If you don’t eat carbs, you must add fat to compensate. Failing to do so could lead to hunger and inadequate nutrition.

There’s no scientific reason to fear fat — as long as you avoid trans fats and choose healthy ones like monounsaturated and omega-3 fats instead.

A fat intake around 70% of total calories may be a good choice for some people on low carb or ketogenic diets.

To get fat into this range, you must choose fatty cuts of meat and liberally add healthy fats to your meals.

SUMMARY

A very low carb diet must be high in fat. Otherwise, you won’t get enough energy or nutrition to sustain yourself.

One of the main mechanisms behind low carb diets is a reduction in insulin levels (3, 4).

Insulin has many functions in your body, such as telling fat cells to store fat and your kidneys to retain sodium (5).

On a low carb diet, your insulin levels go down and your body starts shedding excess sodium — and water along with it. This is why people often get rid of excess bloating within a few days of low carb eating.

However, sodium is a crucial electrolyte. Low sodium levels can become problematic when your kidneys dump too much of it.

This is one reason people experience side effects on low carb diets, such as lightheadedness, fatigue, headaches, leg cramps, and even constipation (6).

The best way to avoid this issue is to add more sodium to your diet. You can do this by salting your foods — but if that doesn’t suffice, try drinking a cup of broth every day.

At the same time, it’s important to remember that the Food and Drug Administration has set the Daily Value for sodium at no more than 2,300 mg per day. Consuming more than this amount can be very dangerous for your health, particularly as a risk factor for high blood pressure (7).

In most Western diets, consuming too little sodium is generally not a concern. In addition, the kidneys are quite good at regulating electrolyte levels and maintaining chemical balance in the body after adjusting to a low carb diet.

SUMMARY

Low carb diets lower your insulin levels, making your kidneys excrete excess sodium. This can lead to a mild sodium deficiency.

Your body is designed to preferentially burn carbs. Therefore, if carbs are always available, that’s what your body uses for energy.

If you drastically cut back on carbs, your body needs to shift to burning fat — which comes from either your diet or your body’s stores.

It can take a few days for your body to adapt to burning primarily fat instead of carbs, during which you will probably feel a little under the weather.

This is called the “keto flu” and happens to most people who go on ultra low carb diets.

If you feel unwell for a few days, you may be tempted to quit your diet. However, keep in mind that it may take 3–4 days for your body to adjust to your new regimen, and full adaptation may take several weeks.

Use your judgment to decide whether this diet is working for you and whether you’re willing to continue. As with any new diet, it’s a good idea to consult a dietitian or another healthcare professional before you start.

SUMMARY

On a low carb diet, it can take a few days to overcome unpleasant symptoms and several weeks for your body to fully adapt. It’s important to be patient and not to abandon your diet too soon.

Low carb diets may offer a potential solution for health conditions like obesity and type 2 diabetes. (8, 9, 10).

However, just cutting back on carbs isn’t enough to lose weight or boost health. The best way to achieve long-term, sustainable weight loss is through small healthy lifestyle changes over time.

Ketogenic diets are often not sustainable in the long term, and dieters often gain weight back when they begin eating carbs again.

For optimal well-being, aim to eat a well-balanced diet and get enough exercise.

Protein Intake

Optimal protein intake depends on your weight (total weight minus body fat percentage) and your activity level. Too much can kick you out of ketosis as the excess protein will turn into glycogen. On the other hand, too little protein can cause muscle loss.

Losing muscle mass is undesirable because it will slow down your metabolism and your body will burn fewer calories. To find out your ideal protein intake, you need to multiply your body mass by your chosen activity level.

The multiplication factor should be between 1. 3 and 2.2 g of protein per 1 kg of weight.

Using your activity level will help you determine your protein intake more accurately. Based on the numbers above, the ideal protein intake for different activity levels would be:

• Minimum protein intake = sedentary lifestyle = 1.3 g x 1 kg lean body mass.
• Light activity = 1.5 g x per kg lean body weight.
• Moderate activity = 1.7 g per 1 kg of lean body weight.
• Very active lifestyle = 2 g x 1 kg lean body weight.
• Maximum Protein Intake = Athlete/Bodybuilder = 2.2 g/kg lean body mass.

Protein intake on a ketogenic diet doesn’t change based on your goal—in other words, it’s the same for weight loss, maintenance, and weight gain.

Is the calculator easy to use?

YesNo

How to find your body fat percentage

1. Use the caliper (preferred method)

2. Use our body fat percentage photo guide.

Minimum calorie intake

There are several factors that determine the minimum calorie level:

• The vital fat mass you cannot lose is 8-12% for women and 3-5% for men.
• To prevent the formation of gallstones, fat intake should be at least 30 grams per day.

Additional Tips

1. First of all, don’t weigh yourself more than once a week. There are natural fluctuations associated with water retention and hormonal balance. If you are a woman, these changes will be more frequent. Just because you don’t see movement on the scale, or even if your weight is going up, doesn’t mean you’re not losing fat. If you are exercising, you may even see a slight increase in weight since muscle is heavier than fat. The important thing here is to focus on fat loss. Don’t rely on the scale alone, use a tape measure, caliper, straps or clothing to see any changes.

2. Recalculate your macros at least once a month. As body weight and body fat change, so will your macronutrient ratio.

10 commandments of the keto diet, the basics of the keto diet that you need to know

4.5/5 – (15 votes)

I have long wanted to write something concise on this topic. One that you can print and carry with you. In general, the basics of the keto diet in 60 seconds:

Keto diet proportions

Basic keto macronutrient ratio:

• 60-75% calories from fat,
• 15-30% of calories come from protein and
• 5-10% calories from net carbohydrates

How to get started on a keto diet

I’ll talk about this separately, but for now you cut carbohydrates, starches, grains and sugar from food and from your head. At all.

Review the keto food list.

Start by reducing your carbohydrate intake (total carbohydrates without fiber) to 20-30 grams daily. Don’t be afraid to drastically cut carbs. It is better to remove all your usual carbohydrates from your diet. Most can stay in ketosis (the body’s natural state of using breakdown products of fat rather than carbs for energy) on 20-30 grams of net carbs per day. A limit of 50 carbohydrates is also suitable for someone, but it is better to increase gradually and slowly. Over time, you will find a carb limit that allows you to stay in ketosis.

Read more of my hit on 11 secrets to successfully starting a keto diet.

We eat and love protein

Keep your protein intake moderate, but don’t go hungry, don’t be afraid of protein. Strive to ensure that protein-rich foods, quality meat or fish are in the diet every day. If protein intake is too low, troubles like hair loss will begin.

Adding good fats

On keto, we increase the proportion of calories that come from healthy fats (saturated, omega-3, monounsaturated). We eat butter, fry in ghee, bacon fat, lard, coconut oil. Add extra virgin olive oil, avocado oil to salads. It is fats that give us a long-lasting feeling of satiety. We DO NOT eat sunflower, linseed, other seed oils. And no margarine, trans fats, hydrogenated fats.

Don’t overeat anything

If your net carb limit is very low (20 grams or less), avoid fruits and desserts, even those that are low in carbs. Keto baked goods, nuts, cheese are all easy to overeat. Avoid them at the start of a keto diet, or eat them infrequently and minimally.

We don’t eat sweets

We don’t eat sugar and all its types. Honey, agave syrup, cane sugar, coconut sugar, glucose, dextrose, etc. Sometimes we use sweeteners: stevia, erythritol. But not at the beginning of the diet for sure. I am 9I haven’t eaten anything sweet for months. No stevia with erythritol, and you can do it, I’m sure.

How many times a day to eat on a keto diet

Eat when you are hungry, even if it is one meal a day. Do not adapt to the 5 meals a day of relatives and children.

You don’t need to deliberately limit the amount of food you eat, but you should stop eating when you feel full, even if the plate is not empty – leave it, put the rest of the food in the refrigerator.

Do I need to count calories on a keto diet

Don’t count calories – listen to your body, including hunger and satiety signals. Ketogenic and low carb diets have a natural appetite control effect and you will eat less.

If for the first time you are trying to figure out where and how much proteins, fats and carbohydrates are contained, then try to count macronutrients through applications. Fat Secret Lifesum.

A food diary is very helpful. Just a sheet of paper, date, time, what and how much they ate. Keeping a diary or using a BJU app helps when starting a keto diet or if you’re struggling to lose weight. When you figure it out, immediately drop the calculations with a clear conscience.

Ketone measurement optional

No, not required, but required if the ketogenic diet is for you treatment protocol. But then the doctor himself will tell you about it and tell you what and how to measure and count.

More water and more salt

Increase the amount of water you drink – at least 2-3 liters per day.
