Rich Breakfast Reduces Hunger All Day
Mo. A University of Missouri researcher has found that eating
a healthy breakfast, especially one high in protein, increases satiety
and reduces hunger throughout the day. In addition, using functional
magnetic resonance imaging (fMRI) the researchers found that eating
a protein-rich breakfast reduces the brain signals controlling food
motivation and reward-driven eating behavior.
healthy, protein-rich breakfasts, such as waffles made with protein
powder, can be a simple strategy for improving appetite control and
knows that eating breakfast is important, but many people still
dont make it a priority, said Heather Leidy, assistant
professor in the MU Department of Nutrition and Exercise Physiology.
This research provides additional evidence that breakfast
is a valuable strategy to control appetite and regulate food intake.

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

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.
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
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.
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.
