Protein-Rich Breakfast Increases Satiety, Reduces Hunger Throughout The Day

May 5, 2011: 12:00 AM EST
Eating a healthy breakfast high in protein increases feelings of fullness and reduces hunger throughout the day, according to a U.S. study. Researchers used functional magnetic resonance imaging (fMRI) to determine that eating a protein-rich breakfast dampens brain signals controlling food motivation and reward-driven eating behavior. For the study, researchers assessed hunger and satiety in 10 teenaged girls who either skipped breakfast or ate breakfasts with either normal or high levels of protein. They measured perceived appetite sensations and hormonal markers combined with psychological reward-driven motivation to eat. fMRI was used to identify brain activation in specific regions related to food motivation and reward. They found that, when compared to breakfast skipping, breakfast meals led to increased fullness and reductions in hunger throughout the morning.
