If you're eating too much, the experts say you can blame your friends.
You ordered a salad, but you're watching someone else eat a fat cheeseburger. Chances are you're going to want one too.
Experts say there's some psychology behind the phrase, "I'll have what he's having."
According to a just-released study in the Journal of the Academy of Nutrition and Dietetics, our eating habits are influenced by our need to fit in.
Fifteen studies examined the societal influence in what we eat. The findings found that people eat more or less when others around them eat more or less.
The study also found people made healthier choices based on the choices others made.
