Different protein sources suppress appetite to different degrees based on how much leucine they contain.
Eating a breakfast with 30 grams of protein increases satiety hormones but does not lead to eating less at the next meal in healthy adults aged 18–80.
When healthy young and older adults consume a 30-gram protein drink made from plants or animals at breakfast, the resulting changes in satiety hormones and feelings of fullness are the same, even though one is a liquid and the other is a solid food.
A 30-gram high-protein breakfast increases plasma GLP-1 and PYY levels more than a low-protein, high-carbohydrate breakfast in healthy young and older adults, but this increase does not lead to lower calorie intake at the next meal.
When healthy adults aged 18–80 consume 30 grams of protein from a plant-based drink or an animal-based solid meal, the reduction in subjective feelings of hunger is the same, even though one is a liquid and the other is a solid.
