A new weight loss study conducted in Israel has revealed that dieters who consume milk or milk products lose more weight on average than those who consume little to no milk products.

The two-year dietary intervention study, of 300 overweight men and women in middle age, was carried out by Ben-Gurion University of the Negev (BGU). The researchers found that regardless of diet, dieters with the highest dairy calcium intake - equal to 12 oz. of milk or other dairy products, lost about 12 pounds (6kg) at the end of two years.
Dieters with the lowest dairy calcium intake - about half a glass of milk, only lost seven pounds on average.
The researchers, led by Dr. Danit Shahar, of BGU's Center for Health and
Nutrition, and the Faculty of Health sciences, also discovered that
levels of vitamin D found in the blood, also affected the success of
weight loss treatments. The results confirmed existing research showing
that overweight participants have lower blood levels of the vitamin.Higher vitamin D levels in successful dieters
"It was known that over-weight people had lower levels of serum vitamin D
but this is the first study that actually shows that serum Vitamin D
increased among people who lost weight," says Shahar. "This result
lasted throughout the two years that the study was conducted, regardless
of whether [participants] were on a low-carb, low fat or Mediterranean
Vitamin D increases calcium absorption in the bloodstream and in
addition to sun exposure can be obtained from fortified milk, fatty fish
and eggs. Americans generally consume less than the recommended daily
requirement of Vitamin D which is found in four glasses of milk (400
The study, which was published in the current issue of the American
Journal of Clinical Nutrition, was part of the Dietary Intervention
Randomized Control Trial (DIRECT) held at the Nuclear Research Center in
Israel in collaboration with Harvard University, the University of
Leipzig, Germany and the University of Western Ontario, Canada.
Some 322 moderately obese people, aged 40 to 65, took part in the study
evaluating low fat, Mediterranean or low-carb diets for two years.
In earlier findings, scientists discovered that low-fat diets aren't the
best way to lose weight, but that dieters are likely to lose more
weight on a Mediterranean diet, or a low-carb diet.
The study was supported by the Israel Ministry of Health and the Israel
Dairy Council, the Israel Chief Scientist Office, German Research
Foundation and the Dr. Robert C. and Veronica Atkins Research
