Protein-rich breakfast may increase satiety

November 19, 2013

A study presented at the Obesity Society’s Annual Scientific Meeting on Nov. 14, shows that eating high protein sausage and egg-based breakfasts may curb hunger throughout the morning, compared with a low-protein breakfast or skipping breakfast.

A group of women, ages 18–55, were given breakfast meals containing approximately 300 calories and similar quantities of fat and fiber. The protein-rich breakfast bowls contained 30–39 g of protein. Participants completed questionnaires to rate aspects of appetite—such as hunger, fullness, and desire to eat—before breakfast and at 30 min intervals between breakfast and lunch. A standard lunch meal of tortellini and sauce was served and subjects were asked to eat until comfortably full.

The researchers found that the participants had improved appetite ratings (lower hunger, more fullness, less desire to eat) throughout the morning after eating a protein-rich breakfast. In addition, they also ate fewer calories at lunch, compared with the low-protein breakfast and breakfast skipping (water only).

“In the USA, many people choose to skip breakfast or choose low protein foods because of lack of high protein convenient choices. These results demonstrate that commercially prepared convenient protein-rich meals can help women feel full until lunch time and potentially avoid overeating and improve diet quality,” said Heather Leidy, Assistant Professor specializing in appetite regulation at the University of Missouri and a co-author on the study.
