Here's another article (USA Today), about men this time.

Scientists analyzed the data on weight change in about 20,000 men over a 12-year period. The men are participants in the Health Professionals Follow-up Study, an ongoing survey of data on men's health conducted by the Harvard School of Public Health.

Overall, men who increased their intake of low-fat dairy foods the most over 12 years did not lose more weight than those who decreased their intake of those foods the most, according to the findings in the March issue of The American Journal of Clinical Nutrition.
"The hypothesis that has been floating around is that increasing dairy can promote weight loss, and in this study, I did not find that," says Swapnil Rajpathak, assistant professor in the Department of Epidemiology and Population Health at the Albert Einstein College of Medicine in New York.

Much of the research supporting dairy's role in weight loss was done by Michael Zemel, director of the Nutrition Institute at the University of Tennessee in Knoxville.
In three small studies (about 30 people in each), Zemel found that dieters on reduced-calorie diets who had three daily servings of low-fat dairy products lost more weight and body fat than those who consumed one serving or less.
