Prepackaged portion-controlled meals can lead to greater weight loss than self-selected portions, research says

Increased portion sizes in Americans’ diets is widely recognized as a contributor to the obesity epidemic, and now new research examines the effect of prepackaged, portion-controlled meals on weight loss. The researchers found that when combined with behavioral counseling as part of a complete weight-loss intervention, a meal plan incorporating portion-controlled, prepackaged, frozen lunch and dinner entrées can promote greater weight loss than a self-selected diet.
