Protein-Rich Breakfast Promotes Weight Loss By Curbing Hunger

July 30, 2014

A study done by a team from Missouri University has found that a healthy and balanced breakfast, especially those high in protein, can increase satiety and make you feel fuller longer. This in turn will help curb your desire to snack too much in between meals. Using fMRI to monitor brain’s activity in response to pre-determined stimuli, eating a protein-rich breakfast actually reduces the brain signals responsible to regulate food motivation and reward-driven eating behavior that causes overeating.

 

“Everyone knows that eating breakfast is important, but many people still don’t make it a priority,” said Heather Leidy, assistant professor in the Missouri University Department of Nutrition and Exercise Physiology. “This research provides additional evidence that breakfast is a valuable strategy to control appetite and regulate food intake.”

 

In the study, Leidy assessed physiological hunger and satiety by measuring perceived appetite sensations and hormonal markers in combination with psychological reward-driven motivation to eat, using fMRI to identify brain activation in specific regions related to food motivation and reward.

 

The researchers decided to target ‘breakfast-skipping’ teens for two reasons, Leidy said. First, breakfast skipping has been strongly associated with unhealthy snacking, overeating (especially at night), weight gain and obesity. Second, approximately 60 percent of adolescents skip breakfast on a daily basis.

 

For three weeks, the teens either continued to skip breakfast or consumed 500-calorie breakfast meals containing cereal and milk (which contained normal quantities of protein) or higher protein meals prepared as Belgium waffles, syrup and yogurt. At the end of each week, the volunteers completed appetite and satiety questionnaires. Right before lunch, the volunteers completed a brain scan, using fMRI, to identify brain activation responses.

 

Compared to breakfast skipping, both breakfast meals led to increased fullness and reductions in hunger throughout morning. fMRI results showed that brain activation in regions controlling food motivation and reward was reduced prior to lunch time when breakfast was consumed in the morning.  Additionally, the higher protein breakfast led to even greater changes in appetite, satiety and reward-driven eating behavior compared to the normal protein breakfast.

 

“Incorporating a healthy breakfast containing protein-rich foods can be a simple strategy for people to stay satisfied longer, and therefore, be less prone to snacking,” Leidy said. “People reach for convenient snack foods to satisfy their hunger between meals, but these foods are almost always high in sugar and fat and add a substantial amount of calories to the diet. These findings suggest that a protein-rich breakfast might be an effective strategy to improve appetite control and prevent overeating in young people.”
