Living with a heavy roommate could keep slender girls in college from gaining weight, according to a new study.Researchers at the University of Michigan say it's because of the behavior of the heavier women.

They found college women who weigh more than average are more likely to diet, exercise, and use weight loss supplements.

The study says the influence of that behavior can rub off on their roommates, preventing them from gaining as much weight as they would otherwise.
