Breakfast is the Most Important Meal of the Day, Improves Brain Function and Helps Prevent Weight Gain

It's certainly true that breakfast is the most important meal of the day. However, statistics show that up to 60 percent of America's youth consistently skip it.

Heather Leidy, an assistant professor in the Department of Nutrition and Exercise Physiology, says eating a breakfast rich in protein significantly improves appetite control and reduces unhealthy snacking on high-fat or high-sugar foods in the evening, which could help improve the diets of more than 25 million overweight or obese young adults in the U.S.

Leidy examines the impact that breakfast consumption has on the amount of daily snacking in young people who habitually skip it.

In her study, 20 overweight or obese adolescent females ages 18-20 either skipped breakfast, consumed a high-protein breakfast consisting of eggs and lean beef, or ate a normal-protein breakfast of ready-to-eat cereal. Every breakfast consisted of 350 calories and was matched for dietary fat, fiber, sugar and energy density.

Study participants ate egg and beef-based foods such as burritos or egg-based waffles with applesauce and a beef sausage patty as part of a high-protein breakfast; Leidy also suggests eating plain Greek yogurt, cottage cheese or ground pork loin as alternatives to reach the 35 grams of protein, according to a press release

The high-protein breakfast contained 35 grams of protein. Participants completed questionnaires and provided blood samples throughout the day. Prior to dinner, a brain scan using functional magnetic resonance imaging (fMRI) was performed to track brain signals that control food motivation and reward-driven eating behavior.

The study showed that a breakfast with high-protein led to increased fullness and improved levels of brain activity through the day.
