What is the main role of protein in relation to satiation during meals?

The main role of protein in relation to satiation during meals is that it triggers feelings of fullness during the meal. Consuming protein-rich foods activates various hormones that signal satiety to the brain, helping individuals feel satisfied and reducing the likelihood of overeating. Protein can also slow down the digestion process, leading to a more gradual release of energy and prolonged feelings of fullness.

While protein does play a role in increasing feelings of fullness after a meal, the immediate effect of starting a meal is often more pronounced. This is crucial for people trying to manage their weight or improve dietary habits, as experiencing fullness during meals can discourage excessive calorie intake. Additionally, protein promotes higher thermogenesis, which refers to the increase in calorie burning through digestion and metabolism. However, its most direct connection to satiation occurs during the meal itself rather than primarily after eating. The concept of protein promoting fat storage does not align with its role in managing satiety or energy balance.
