Effect of a high-protein breakfast on the postprandial ghrelin response
Ghrelin is a hormone that stimulates appetite. This study found that a high protein breakfast resulted in lower ghrelin levels, thus leading to higher satiety. I usually try to steer patients towards a higher protein breakfast (such as real peanut butter, high omega 3 eggs…) because these seem to keep them full longer. Unfortunately, look at what most breakfasts consist of–high glycemic index carbs that lead to earlier hunger and increased overall caloric intake through the day.
