Scientists have found that calcium found in dairy products and other foods can help promote weight loss in a big way. Although foods containing calcium are the best way to receive this nutrient, supplements can also help. The National Health and Nutrition Examination Survey has consistently shown that calcium intake is linked to body weight. Other studies show that the people who get the least amount of calcium are up to 6 times more likely to be overweight than those who get the most calcium. No need to take extremely high doses of calcium—1,000 mg to 1,500 mg per day will do the trick. Also note that your body can’t absorb too much calcium at once. Take a 500 mg supplement in the morning and one in the evening instead of all at once. Men should watch their calcium intake as it can lead to prostate problems. Women past menopause should be taking at least 1,500 mg or more a day.
