Whether dairy foods, including cheese, help in weight control is controversial. A 2009 study in Nutrition & Metabolism, funded by the National Dairy Council, suggests that cheese and other dairy foods may help prevent weight gain after dieting; another study found that regular cheese eaters gained less weight over time than those who ate cheese less often. But other studies, including one from Johns Hopkins in 2008, have found that people who eat more cheese tend to be more overweight.
