April 16, 2004 -- Stocking the refrigerator with milk, cheese,
and yogurt may make it easier to lose those extra pounds and burn fat without
cutting back drastically on calories, according to new research.
Although calories still count, the study showed that obese
adults who ate a high-dairy diet lost significantly more weight and fat than
those who ate a low-dairy diet containing the same number of calories.
"If you compare a dairy-rich versus a dairy-poor diet you
can nearly double the rate of weight and fat loss with the same level of
calorie restriction," says researcher Michael Zemel, PhD, professor of
nutrition and medicine at the University of Tennessee in Knoxville.
Zemel says the study also showed that eating three to four
servings of dairy products a day is more effective at enhancing weight loss
efforts than calcium supplementation alone with pills or calcium-fortified
The study appears in the April issue of Obesity
Research and was supported by the National Dairy Council, a WebMD
Previous studies have already shown that dieters who eat a
calcium-rich diet are more successful at losing weight, but this study
indicates that it's more than just the calcium in dairy products that helps
"Calcium is a critical factor in controlling what your body
does with calories, and dairy is an even more critical factor," says Zemel.
"Without changing how many calories we take away, we can alter how much
weight and fat you lose."
Dairy Products Beat Calcium for Weight Loss
In the study, researchers compared the effects of three
different calorie-restricted diets on weight loss in 32 obese adults. Each of
the participants reduced their daily calorie intake by about 500 calories per
day for 24 weeks and were divided into three groups:
High-dairy. Total calcium intake of 1,200-1,300 milligrams per day
from three to four servings of dairy foods, specifically milk, hard cheese, and
High-calcium supplemented/low-dairy. Total calcium intake of
1,200-1,300 milligrams per day made up of no more than one serving of dairy per
day plus an 800-milligram calcium supplement.
Low-calcium/low-dairy. Total calcium intake of 400-500 milligrams
per day with no more than one serving of dairy per day and a placebo
