The Beneficial Effects of Healthy Snacks on Appetite Control, Satiety, and Reward-driven Eating Behavior in Young People

Completed · Not applicable

Conditions studied: Obesity

In brief

The purpose of this study is to examine the effects of normal vs. protein-rich afternoon snacks on appetite control, satiety, and reward-driven eating (particularly in the evening) in young people. Indices of attention and mood will also be assessed. Study hypotheses include the following: 1. The consumption of a high-protein, soy-rich afternoon snack will lead to significant improvements in appetite control and satiety, reductions in food motivation and reward, and will delay the drive to eat in normal to overweight young people. 2. The consumption of a high-protein, soy-rich afternoon snack will lead to reduced unhealthy, evening snacking, particularly on foods high in fat and/or sugar, in normal to overweight young people. 3. The daily consumption of a high-protein, soy-rich afternoon snack will lead to significant improvements in afternoon alertness, concentration, fatigue, and well-being in normal to overweight young people.
