The Science Behind Calcium and Weight Loss

Recent studies have shed light on the intriguing connection between calcium intake and weight management. Researchers have discovered that calcium, particularly from dairy sources, may play a crucial role in regulating metabolism and promoting fat loss. But how exactly does this mineral contribute to shedding those extra pounds?

Calcium’s Impact on Fat Cells

Dr. Michael Zemel, director of The Nutrition Institute at the University of Tennessee at Knoxville, has been at the forefront of this research. His studies on both mice and humans have revealed that calcium stored in fat cells significantly influences how the body processes and stores fat. The higher the calcium content in a fat cell, the more fat it burns, potentially leading to greater weight loss.

The Mouse Study

In a groundbreaking experiment, Dr. Zemel used mice bred to be obese. After feeding them a high-fat, high-sugar diet for six weeks, resulting in a 27% increase in body fat, he placed the mice on a restricted-calorie diet. Some mice received calcium supplements, while others did not. The results were striking:

• Mice without calcium supplementation lost 8% of body fat
• Mice receiving calcium supplements lost 42% of body fat
• Mice on a medium-dairy diet lost 60% of body fat
• Mice on a high-dairy diet lost an impressive 69% of body fat

These findings suggest that calcium, especially from dairy sources, can significantly enhance fat loss when combined with a calorie-restricted diet.

Human Studies

Translating these results to humans, Dr. Zemel conducted a study involving 32 obese individuals on a low-calorie diet. The participants were divided into three groups:

1. High-dairy diet
2. Low-dairy diet with calcium supplements
3. Low-calcium, low-dairy diet

After 24 weeks, all groups experienced significant fat loss. However, the high-dairy group lost an additional five pounds compared to the other groups. Moreover, the dairy group’s waists shrank by more than an inch and a half, while the others lost only about a quarter of an inch. Notably, the yogurt group primarily lost belly fat, which is associated with a higher risk of heart attacks and other health problems.

The Calcium Effect on Long-Term Weight Management

Dr. Robert Heaney, an expert in bone biology and calcium nutrition from Creighton University, has observed the “calcium effect” in his own research. Over a 20-year period, he studied nearly 1,000 women and found that those with the highest dairy intake maintained a stable weight, while those with the lowest dairy intake gained an average of one pound per year.

This long-term study suggests that consistent calcium intake from dairy sources may play a crucial role in weight maintenance, particularly for women in midlife who tend to experience gradual weight gain.

How Calcium Promotes Weight Loss

Understanding the mechanisms behind calcium’s weight loss effects is crucial for leveraging its benefits. Let’s explore the three main ways calcium contributes to weight management:

1. Increased Thermogenesis

Calcium provides small increases in thermogenesis, which is the body’s core temperature. This slight elevation in temperature may boost metabolism, prompting the body to burn more fat. While the effect is subtle, over time, it can contribute to meaningful weight loss when combined with a balanced diet and regular exercise.

2. Enhanced Satiety

Calcium-rich foods, particularly dairy products, have been shown to increase feelings of fullness. This satiety effect can help reduce overall calorie intake by naturally curbing appetite. Dr. Heaney notes that whole-fat milk, in particular, has a high satiety value, which may lead to reduced food consumption throughout the day.

3. Increased Fat Excretion

Some studies suggest that calcium may bind to dietary fat in the digestive tract, reducing its absorption and increasing its excretion. This mechanism could potentially lead to a reduction in overall calorie absorption, contributing to weight loss over time.

Optimizing Calcium Intake for Weight Loss

To harness the weight loss benefits of calcium, it’s essential to incorporate it strategically into your diet. Here are some guidelines to help you optimize your calcium intake:

Recommended Daily Intake

For weight loss purposes, Dr. Zemel recommends consuming three servings of fat-free or low-fat dairy products every day. This approach ensures you’re getting an adequate amount of calcium while keeping calorie intake in check.

Choosing the Right Sources

While calcium supplements can be beneficial, research suggests that calcium from dairy sources may be more effective for weight loss. Opt for a variety of dairy products such as milk, yogurt, and cheese to maximize the benefits.

Timing Your Intake

Spreading your calcium intake throughout the day may be more beneficial than consuming it all at once. This approach helps maintain steady calcium levels in the body and may enhance its metabolic effects.

Potential Drawbacks and Considerations

While the weight loss benefits of calcium are promising, it’s important to consider potential drawbacks and limitations:

Calorie Balance

Dr. Heaney emphasizes that calcium alone won’t lead to weight loss if you’re not also reducing overall calorie intake. Adding dairy to an already high-calorie diet won’t produce significant results. The key is to incorporate calcium-rich foods as part of a balanced, calorie-controlled diet.

Individual Variations

The effectiveness of calcium for weight loss may vary among individuals. Factors such as age, gender, baseline calcium intake, and overall diet composition can influence the results.

Lactose Intolerance

For individuals with lactose intolerance, consuming large amounts of dairy products may cause digestive discomfort. In such cases, lactose-free dairy options or non-dairy calcium sources may be more suitable.

Beyond Weight Loss: Additional Benefits of Calcium

While the focus of this article is on calcium’s role in weight management, it’s worth noting the numerous other health benefits associated with adequate calcium intake:

• Strengthening bones and teeth
• Potential reduction in colon cancer risk
• Improved digestive health
• Enhanced muscle function
• Support for cardiovascular health

These additional benefits underscore the importance of maintaining optimal calcium levels, regardless of weight loss goals.

Incorporating Calcium into Your Weight Loss Plan

To effectively use calcium as part of your weight loss strategy, consider the following tips:

1. Choose Low-Fat Dairy Options

Opt for fat-free or low-fat dairy products to keep calorie intake in check while still benefiting from calcium’s weight loss properties. Greek yogurt, skim milk, and low-fat cottage cheese are excellent choices.

2. Experiment with Calcium-Rich Recipes

Incorporate calcium-rich ingredients into your meals creatively. Try smoothies made with yogurt and milk, salads topped with low-fat cheese, or calcium-fortified plant-based milk in your morning coffee.

3. Consider Non-Dairy Sources

If you’re lactose intolerant or following a vegan diet, explore non-dairy calcium sources such as leafy greens, fortified plant-based milk, tofu, and almonds.

4. Pair Calcium with Vitamin D

Vitamin D enhances calcium absorption, so ensure you’re getting enough through sunlight exposure, fatty fish, or supplements as recommended by your healthcare provider.

5. Stay Consistent

Remember that the weight loss benefits of calcium are most pronounced when intake is consistent over time. Make calcium-rich foods a regular part of your daily diet for the best results.

The Future of Calcium and Weight Loss Research

As the connection between calcium and weight loss continues to intrigue researchers, we can expect more studies to further elucidate this relationship. Future research may focus on:

• Optimal calcium dosages for weight loss
• The interplay between calcium and other nutrients in weight management
• Long-term effects of increased calcium intake on body composition
• Personalized approaches to calcium supplementation based on individual factors

These ongoing investigations promise to refine our understanding of calcium’s role in weight loss and may lead to more targeted nutritional strategies for those seeking to manage their weight effectively.

Conclusion: Harnessing the Power of Calcium for Weight Loss

The emerging research on calcium’s role in weight loss offers an exciting avenue for those looking to shed excess pounds. By incorporating calcium-rich foods, particularly dairy products, into a balanced, calorie-controlled diet, individuals may enhance their weight loss efforts and improve overall health.

However, it’s crucial to remember that calcium is not a magic bullet for weight loss. It should be viewed as part of a comprehensive approach that includes a nutritious diet, regular physical activity, and healthy lifestyle habits. As with any significant dietary change, it’s advisable to consult with a healthcare professional or registered dietitian to ensure that your calcium intake aligns with your individual health needs and weight loss goals.

By understanding the science behind calcium and weight loss and implementing strategic dietary changes, you can potentially “drink yourself skinny” – or at least give your weight loss efforts a significant boost. Remember, consistency is key, and the benefits of calcium extend far beyond the scale, contributing to overall health and well-being.

Calcium: Drink Yourself Skinny

Dairy products boost metabolism and aid weight loss.

• The Science
• How It Works

Calcium’s leading role is legendary. In fact, there seems to be no end to calcium’s repertoire: It strengthens bones and teeth and new studies suggest that it may also prevent colon cancer, and even keep Montezuma’s revenge at bay.

There’s also good evidence that diets high in calcium are associated with reduced rates of being overweight or obese.

“At midlife, women tend to gain one-quarter to one-half a pound per year whether they want it or not, and it all goes to their waist,” says Robert Heaney, MD, an internationally recognized expert in bone biology and calcium nutrition with Creighton University in Nebraska.

“We’ve found that women with the highest dairy intake have an average weight gain of zero, and those with the lowest dairy intake gained a pound per year,” Heaney tells WebMD.

There’s one catch: You also must cut back on calories for weight loss to happen. “Dairy will only help you lose weight if you have reduced calories. If you add it to what you eat all the time, it won’t make a whit of difference,” Heaney explains.

Michael Zemel, PhD, director of The Nutrition Institute at the University of Tennessee at Knoxville, is actually the hero of this tale.

In studies of both mice and men, Zemel and colleagues have been the first to show that calcium stored in fat cells plays a crucial role in regulating how fat is processed and stored by the body. The more calcium there is in a fat cell, the more fat the cell will burn — and the greater the weight loss, Zemel says.

The mouse evidence: In one study, Zemel used mice that were specially bred to be obese. He fed the mice a high-fat, high-sugar diet for six weeks. All had a 27% increase in body fat.

He then put the mice on a restricted-calorie diet, and gave calcium to two groups of them.

The calcium made a big difference. Mice that didn’t get any calcium had an 8% loss of body fat. Mice getting calcium supplements had a 42% decrease in body fat.

But calcium from dairy products produced the best weight-loss results. Mice on a medium-dairy diet had a 60% decrease in body fat, while those on a high-dairy diet lost 69% body fat.

The human evidence: A study of 32 obese people on a low-calorie diet divided them into three groups: those whose diet was high in dairy, those who ate little dairy but took calcium supplements, and those whose diets were low-calcium and low-dairy. After 24 weeks, everyone lost a lot of fat, but those who ate the dairy-rich diet lost five pounds more.

The dairy eaters’ waists also shrank by more than an inch and a half — the others lost only about one-quarter inch. Turns out, the yogurt group lost mostly belly fat, Zemel reports. Excess fat in the abdominal area has been linked to a higher risk of heart attack and other health problems.

Heaney has found “the calcium effect” in five of his own studies, investigating close to 1,000 women over a 20-year period. “Those with highest dairy intake had an average weight gain of zero. Those with the lowest dairy intake had an average weight gain of a pound per year,” he tells WebMD.

Calcium provides small increases in thermogenesis, the body’s core temperature, Zemel explains. This may boost metabolism, which can prompt our bodies to burn fat.

If weight loss is your goal, eat three servings of fat-free or low-fat dairy products every day, he advises.

But cardiologists (heart specialists) may not like this advice: Whole-fat milk works even better in a weight-loss plan, says Heaney. “In fact, whole-fat milk has a satiety value so you naturally won’t eat so much. A high-carbohydrate diet leaves you feeling hungry all the time.”

The Ultimate Guide on Calcium and Weight Loss

Overview

Weight Loss Benefits

Maximize Weight Loss

How’s this for a pair of health benefits: Calcium helps you build strong, healthy bones and may help you lose pesky belly fat at the same time!

Talk about a win-win. But there’s more.

A healthy weight is also a key component of healthy bones in its own right. See, a healthy body weight puts less strain on your joints and skeleton. And it lessens the bone-damaging inflammation obesity can trigger too!

Here’s everything you need to know about calcium and fat loss.

Calcium and Weight: What Science Says

If taking calcium for weight loss sounds a little too good to be true, don’t worry. There are three science-backed findings on calcium’s role in weight loss to help calm any doubts you may have:

1. 1. It helps you burn more fat
   2. It makes you feel fuller for longer
   3. It helps your body get rid of fat (through stools)

Now, let’s take a closer look at the science behind that trio of findings.

1. Calcium Helps Burn Fat

To answer the question, “Does calcium burn fat?”, let’s turn our attention to the research.

A randomized, double-blind study [2] compared the effect of a 15-week weight-loss program on body fat. The sample of the study was 63 overweight or obese women with an average age of 43. All of the women consumed less than 800 milligrams of calcium a day before the study began.

The women were randomly assigned to receive 600 milligrams of supplemental calcium with five micrograms of vitamin D twice a day, or a placebo.

Women who took the calcium and vitamin D supplement during the study and were consuming less than 600 milligrams of calcium a day before the study saw a significant decrease in fat mass and body weight. This study provides support that calcium does enhance fat burning.

2. Calcium Promotes Lasting Satiation

As it turns out, the link between consuming calcium and losing weight can also be tied to your appetite. The vitamins and minerals within your meal all play a role in how long it takes for you to feel hungry again. And calcium plays a starring role.

Researchers tested the effects calcium has on appetite in 13 men and seven women in a double-blind study [3]. There were four preload meal variations for the participants to try. And they were: a low-calcium/low-protein control, a high-calcium preload, a high-protein preload, and a high-calcium/high-protein preload.

After the high-protein/high-calcium trial, total energy intake (calories consumed) was 3,419 calories. This was the lowest amount of calories consumed in any of the meal variations.

The next best was the high-calcium preload day, which totaled 3,501 calories. The high-protein preload trial was third, with 3,699 calories consumed. The least effective was the low-calcium/low-protein preload trial. On that day 4,126 calories were consumed.

Ultimately, researchers found preloading with protein led to almost perfect energy compensation. They also found calcium, with or without protein, suppressed appetite.

3.

Calcium Increases Fat Excretion

Not only does consuming calcium make us feel fuller longer so that we eat less, but it also helps our bodies expel more fat. Humans typically excrete about 2 grams of fat in stools each day. But recent studies show calcium can increase that number significantly. That’s right, when it comes to calcium and fat absorption, calcium does indeed help you excrete more fat in your stools.

A review and meta analysis [4] of randomized control trials was published in 2009. The results of these studies show increasing calcium intake from 400–500 mg per day to 1241 mg per day increases the amount of fecal fat. On average, the participants in the studies lost 5.2 g of fat in their stools!

How to Maximize Calcium’s Fat-Burning Effect

So that’s the science behind calcium and weight loss. Granted, you have to do more than take calcium to lose weight. As you know, proper nutrition and exercise play a key role as well. But when it comes to keeping excess pounds off, every little bit helps.

So what’s the best way to incorporate calcium into your diet?

To get the most benefit, take supplemental calcium and vitamin D with breakfast. Research shows higher calcium and vitamin D intake at breakfast [6] increases the rate of fat burning that day.

But here’s the thing: Getting enough calcium from your diet alone can be tough. The recommended total calcium intake for adults is 1000–1200 mg per day. But the average Western diet only provides approximately 500 mg of calcium daily. That’s why calcium supplements are a great way to reach your dietary allowance and help you reap those weight-loss benefits too — if you choose the right one.

AlgaeCal Plus is a plant-based calcium supplement (all natural with no side effects) that provides all 12 of the other essential bone-supporting minerals. Plus, it contains 720 mg of calcium per serving — which leaves enough room for adding plenty of calcium-rich foods to your diet.

Traditional rock calcium supplements typically provide a large single dose of calcium on its own (or with vitamin D). This results in excessive calcium intake without the right balance of other nutrients to direct calcium into bone. AlgaeCal Plus provides 720 mg of calcium along with a naturally occurring trace mineral complex and added vitamins and minerals, which facilitate the absorption and direction of calcium.

According to Lara Pizzorno, bone-health expert and best-selling author of Healthy Bones Healthy You!, taking more than 1500 mg can lead to adverse effects.

So play it safe. Include calcium-rich foods in your diet and take the recommended daily dose of AlgaeCal Plus to reap those bone-building and waist-slimming benefits of consuming calcium — minus any harmful side effects.

Hypercalcemia (hypocalcemia) – health articles

11/10/2022

“Extra” calcium, as well as its lack, is not beneficial for the body, causing pathologies of internal organs. Calcium is one of the most important “building” elements, thanks to which various processes in the body are regulated. The main share is involved in the development of the skeleton, in the growth of teeth, nails, hair.

Hypercalcemia – high calcium content can cause malfunction of the stomach, kidneys (reduced glomerular filtration rate), heart muscle, nervous system.

Hypocalcemia – low free calcium in the blood can be caused by endocrine diseases, including hypoparathyroidism (pseudohypoparathyroidism), thyrotoxicosis, pheochromocytoma and parathyrocrinin deficiency. Metastases in neoplasms, kidney disease, pancreas, sepsis have a negative effect.

It is important to determine the causes of both excess and shortage of the element.

Causes

The main causes of hypercalcemia are an excess of parathyroid hormone in the body (hyperparathyroidism), oncology and long-term use of calcium preparations.
Hypocalcemia almost always develops against the background of parathyroid hormone deficiency, which is produced by the upper and lower parathyroid glands. Interacting with the hormone calcitonin (thyroid gland), the exchange of phosphorus and calcium in the body is regulated.

An excess of calcium, just like a deficiency, develops with deviations in the functioning of organs and systems.

Symptoms

The first signs of hypercalcemia may not be noticeable, and only a random blood test will indicate problems. The appearance of obvious symptoms of increased calcium in the blood depends on the duration of this condition, the rate of development, and the severity of the underlying disease.

These symptoms are manifested by the main systems of the body: nervous, muscular, digestive, urinary, cardiovascular, eye and skin diseases. The patient’s memory deteriorates, lethargy, drowsiness, depressive states, weakness and pain in the muscles, restless legs syndrome at night, loss of appetite, constipation, nausea, gag reflex and belching appear. Weight loss is possible against the background of pancreatitis, cholelithiasis, stomach ulcers with high acidity. Develops arthritis and arthrosis, gout.

Hypocalcemia is often combined with a lack of potassium, which leads to excessive excitability of neurons. As a result, there are muscle cramps (shoulders, hands, larynx, facial muscles). Skin sensitivity is also disturbed, there are sensations of burning or numbness. Hemorrhagic syndrome develops, which is manifested by increased bleeding. Blood clotting is reduced. There are dystrophic changes in the tissues, defects in the teeth, brittle nails, dull hair, dry skin, heart rhythm is often disturbed, and cataracts develop.

Diagnosis

If symptoms of hypocalcemia are detected, it is necessary to consult an endocrinologist. To make a diagnosis, as a rule, the following are prescribed: a general blood and urine test, electrocardiography, densitometry (analysis of bone density), MRI of internal organs.

Blood and urine tests are also done for hypercalcemia. In addition, x-rays of the chest, skull, and extremities may show bony lesions.

Treatment

The initial stage of hypercalcemia, caused by excessive consumption of foods and drugs containing calcium, the problem of a slight increase in the amount of calcium in the human body will help to solve: changing the diet towards reducing the amount of foods containing a large amount of calcium. Adjustment of doses, replacement or refusal of drugs containing calcium. With healthy kidneys, sufficient water intake, preferably distilled (no more than 2 months).

If hypercalcemia has developed against the background of serious illnesses, then the treatment is aimed at the underlying disease and cleansing the body of excess calcium. During normal kidney function, calcium is usually flushed out with diuretics and intravenous saline. In severe conditions, hemodialysis is performed (purification of the blood from decay products). If the process of increased calcium excretion from the bones cannot be stopped, then hormonal preparations are used.

The main task in case of hypocalcemia is to compensate for calcium deficiency in the body. In addition, treatment is aimed at eliminating the cause of the disease. So, with hypoparathyroidism (lack of parathyroid hormone), hormone therapy is prescribed. The chronic form of hypocalcemia is treated with regular intake of calcium tablets and vitamin D. In addition, measures are taken to normalize the level of magnesium, potassium and protein in the blood.

Calcium | Tervisliku toitumise informatsioon

The total mass of calcium in the human body is about 2% of the total body weight and 40% of the mass of minerals. 99% i.e. 1000-1500 g of calcium is found in the human skeleton in the form of insoluble salts. The rest is in the teeth, soft tissues and extracellular fluid. In the bones of an adult, about 20% of calcium is replaced per year.

Calcium is needed:

• to perform structural functions, being part of the human skeleton, its teeth and other tissues,
• to ensure tissue metabolism, maintain normal blood vessel wall capacity,
• for normal muscle function,
• for blood coagulation processes,
• to regulate blood pressure and cholesterol levels,
• for normal kidney function,
• for the transmission of nerve impulses.

Common symptoms of calcium deficiency:

• muscle cramps;
• bone softening (osteomalacia),
• osteoporosis, or low bone density.

Calcium absorption is primarily aided by vitamin D, but fats, magnesium and other nutrients also play a role. Calcium absorption is hindered by oxalates, found in spinach and sorrel, for example, as well as phytates, found in grains, alcohol, coffee, salt, and sugar.

Excessive intake of calcium can cause the following:

• Large amounts of calcium can unbalance the recommended ratio of minerals in the body.
• With excessive amounts of calcium or its incorrect proportions with phosphorus and magnesium, calcium is deposited in the muscles, myocardium and kidneys, kidney stones may occur.
• Very high doses of calcium and vitamin D lead to hypercalcemia, which can cause intense calcification of bones, tissues and organs, especially the kidneys.
• Prolonged excess of calcium disrupts the functioning of nervous and muscle tissue, blood clotting, normal absorption of zinc by skeletal cells.
• Calcium intake in excess of 2000 mg per day increases the risk of prostate cancer in men.

The best sources of calcium are milk and dairy products, fish, dark green parts of plants. People who eat a mixed diet and consume milk get about 75% of their calcium from dairy products.
