Talk about calcium what do you first think in your mind? Food, supplements, nutrition…..Been you think calcium also can help to lose weight?
Boosting calcium consumption spurs weight loss, according to a study published in the most recent issue of the British Journal of Nutrition, but only in people whose diets are calcium deficient.
Angelo Tremblay and his team at Université Laval’s Faculty of Medicine made the discovery in a 15-week weight loss program they conducted on obese women. The participants consumed on average less than 600 mg of calcium per day, whereas recommended daily intake is 1000 mg. In addition to following a low calorie diet, the women were instructed to take a total of 1200 mg of calcium. Those who took the calcium tablets lost nearly 6 kg over the course of the program, the researchers found, compared to 1 kg for women in the control group.
“Our hypothesis is that the brain can detect the lack of calcium and seeks to compensate by spurring food intake, which obviously works against the goals of any weight loss program,” said Angelo Tremblay, holder of the Canada Research Chair in Environment and Energy Balance. “Sufficient calcium intake seems to stifle the desire to eat more,” he added.
Consuming sufficient calcium is therefore important to ensuring the success of any weight loss program. According to the researcher, over 50% of obese women who come to the clinic run by his research team do not consume the recommended daily intake.
Professor Tremblay and his team have studied the link between calcium and obesity for several years. Their first findings, published in 2003, revealed that women who consumed diets poor in calcium had more body fat, bigger waistlines, and higher bad cholesterol levels than those who consumed moderate or large amounts of calcium. A second study showed that the more people reduced their consumption of dairy products over the six-year period examined, the more weight and body fat they gained and the bigger their waistlines grew. In 2007, Angelo Tremblay and his team established a direct link between calcium and a lower cardiovascular risk profile among dieters.
Benefits of Calcium
Why calcium is important to people wanting to achieve or maintain a healthy weight, what foods have the best sources of calcium and provide tips to increase your daily calcium intake.
Most nutritionists agree that in order to make sure your body gets all the nutrients it needs to stay healthy you should eat the widest possible variety of foods. This principle is often overlooked by dieters who restrict the types of food they eat in order to lose weight.
If your diet is restrictive, or is simply low in calcium and calcium rich foods, you would be well advised to remember that calcium helps the body to function in many important ways.
For example, calcium is believed to help:
- Strengthen our bones and teeth
- Help our muscles function properly
- Regulate our heart
- Keep our nervous system healthy
- Activate and regulate certain enzymes and hormones such as insulin
- Our body metabolize or burn body fat
- Us to lose weight more efficiently.
However, because calcium can be secreted through sweat, overly active people may require even more calcium than most.
