Taking a calcium supplement containing 800 of calcium per day did not increase weight loss in women who were dieting according to a 3-month study from researchers at Ohio State University in Columbus, Ohio, USA. Although some studieshave suggested that increasing calcium might increase weight loss or reduce weight gain, other studies have not.

Studies have suggested that a higher calcium intake may help to prevent weight gain or, as some have suggested, even cause weight loss. Among American Indians, those with a higher calcium intake—greater than 873 mg per day—only weighed 1.8 pounds less than those with a low calcium intake of less than 313 mg per day.

“There is no evidence to support the use of calcium supplementation as a public health intervention to reduce weight gain or body fat in healthy children,” concludes a new review paper from researchers at Menzies Research Institute in Hobart, Australia.

A normal calcium diet containing 1200 mg of calcium per day slightly increases fat excretion by 2.7 grams or 24 fat calories per day compared to a low calcium diet containing only 400 mg per day, but doubling calcium intake to 2500 mg per day does not increase fat excretion any further according to a study from the Nutrition and Toxicology Research Institute Maastricht in Maastricht, The Netherlands.

Consuming lots of dairy while on a diet does not increase weight loss according to a recent study from the Unversity of Vermont. Men and women on a high dairy diet lost an average of 20 pounds compared to 21 pounds for those on a low dairy diet.

Women who consumed less than 1200 mg of calcium per day and who were given a 1000 mg calcium supplement per day were 11 percent less likely to gain either a small amount of weight, defined as 2-7 pounds, or more moderate weight gain, defined as greater than 7 pounds according to a study from Kaiser Permanente of Northern California.

Men and women who consumed three servings of a beverage containing green tea, caffeine and calcium, increased the amount of calories burned each day by 106 calories per day or by 4.6 percent according to a new study from researchers from Lausanne University in Lausanne, Switzerland and Purdue University in West Lafayette, Indiana, USA.

Dietary calcium from dairy products reduces fat absorption, but a supplement of calcium carbonate does not according to a new study from the University of Copenhagen in Denmark.

A number of studies have found that a higher calcium intake, such as from dairy, is associated with less weight gain. A new study by researchers from Albert Einstein College of Medicine in Bronx, New York and several researchers from the Harvard Medical School in Boston, Mass., including Walter Willett, did not find this in men.

People who consume the most dairy are least likely to have a large waist, least likely to have high blood pressure, and least likely to have metabolic syndrome according to a study from Iran.

Overweight and obese men in Portugal are less likely to drink milk than normal weight men according to a new study, suggesting that milk may help to prevent obesity.

A high-dairy diet which included three servings of dairy per day and 1200 mg of calcium caused obese black adults to lose 4.8 pounds of body fat and gain 2.4 pounds of muscle in six months without dieting according to a new study from Dr. M. Zemel from the University of Tennessee in Knoxville, Tennessee.

Calcium intake has been associated with lower body weight. It appears to work by inhibiting lipogenesis (the production of fat from carbohydrates), increase lipogenesis (the release of fat from fat cells), increase fat excretion, and may increase core body temperature according to a review paper from the University of Wisconsin in Madison, Wisconsin.

Increasing calcium from 500 mg per day to 1000 mg was estimated to reduce the gain in body fat by 9.7 pounds in two years according to a recent study.

Women put on a high calcium diet, consuming an average of 1131 mg of calcium per day, did not lose weight or gain less weight than women eating a low calorie diet, containing an average of 742 mg per day according to a new study from Purdue University in West Lafayette, Indiana.

Numerous studies have found that people who eat more calcium tend to weigh less than people who eat less. However, a new study from Australia found that people lost just as much weight on a high protein, moderate calcium diet compared to those eating a high dairy protein, high calcium diet.

Whole milk consumption is associated with lower body weight in children according to a new study from Italy.

Consuming three or more servings of dairy per day reduces the risk of obesity by 27 percent in men and 31 percent in women compared to those who consume less than 1.6 servings per day according to study out of Iran.

Children 6- to 11-years-old drank four times as much milk as any other beverage in 1977-1978, but only 1.5 times as much milk as soft drinks by 1994-1996 according to the Institute of Medicine’s report on Childhood Obesity (2004, p. 33).

Americans are consuming 135 percent more sweetened beverages, 38 percent less milk and 278 more calories than we did in 1977-1978 according to a new study.

A high-calcium, high dairy diet causes 70 percent more weight loss than a low calcium diet according to a new study.

People on a milk-only diet lost 20.7 pounds in four months compared to 15.4 pounds for those on a milk-plus-one-food-per-day diet versus 3.7 pounds for those on a low-calorie diet alone, despite the fact that the people on the milk-only diet were supposed to eat the same number of calories as the low-calorie diet, and the milk-plus-one-food diet contained considerably more calories.

The higher a woman’s calcium intake, the lower her risk of extreme levels of body fat. Higer intakes of calcium also lower a man’s risk, however, the effect does not appear to be dose-dependent. That is, in men, ever increasing doses do not cause a greater and greater decrease in risk the way they do in women.

People on a high-calcium, high-dairy, reduced-calorie diet for six months lost 5.5 pounds more than those on a low-dairy diet supplemented with extra calcium, and 9.8 pounds more than a low-calcium diet according to a study from researchers at the University of Tennessee.

Increasing dietary calcium intake from an average of 447 mg per day to 1,029 mg per day cause obese blacks to lose approximately 10.8 pounds of body fat after one year according to a study from researchers at the University of Tennessee.
