Heavy adults who believe drinking diet soda will help them lose or keep weight off should think again. Researchers at the Johns Hopkins Bloomberg School of Public Health who examined national patterns in adult diet beverage consumption and calorie intake found that overweight and obese adults who drink diet beverages consume more calories from food than obese or overweight adults who drink regular soda or other sugary beverages. The results are featured in the January 14 issue of the American Journal of Public Health.
