In 18-55-year-old women, eating protein-rich breakfast can help curb hunger throughout the morning, reveals study.
"Eating a breakfast rich in protein significantly improves appetite control and may help women to avoid overeating later in the day," Kevin C. Maki, principal investigator of the study and a research scientist with Biofortis Clinical Research, a Merieux NutriSciences company, said.
All of the breakfast meals contained approximately 300 calories and similar quantities of fat and fiber. The protein-rich breakfast bowls contained 30 to 39 grams of protein.
Participants completed questionnaires to rate aspects of appetite - such as hunger, fullness, and desire to eat- before breakfast and at 30 minute intervals between breakfast and lunch. A standard lunch meal of tortellini and sauce was served and subjects were asked to eat until comfortably full.
Study participants had improved appetite ratings (lower hunger, more fullness, less desire to eat) throughout the morning after eating each protein-rich breakfast, and also ate fewer calories at lunch, compared with the low-protein breakfast and breakfast skipping (water only).
The study was presented at The Obesity Society's annual scientific meeting in Atlanta.
