The hypothalamus in the brain controls appetite and satiety (fullness). Hormones such as glucagon-like peptide-1, peptide YY and glucagon that are secreted by various organs and tissues in the body influence it. Dietary proteins strongly influence these hormones, which helps explain why protein is important for weight loss and maintaining muscle during dieting. A study from the University of Copenhagen in Denmark found that the protein content of a meal had a strong influence on these hormones. Researchers measured the effects of normal (14 percent energy from protein), medium high (25 percent protein) and high protein (50 percent protein) intake on hormones controlling appetite and satiety. The high-protein meal had the greatest effects. Increasing protein intake during dieting will promote satiety and prevent hunger. (American Journal Clinical Nutrition, 97: 980-989)
