1. Satiety and Hunger Hormones

Protein is the most satiating macronutrient. High-protein meals suppress ghrelin (the hunger hormone) while stimulating peptide YY and GLP-1, keeping you full for hours.

2. The Thermic Effect of Protein

Digesting protein is highly energy-intensive. While fat and carbs consume only 5-10% of their energy during digestion, protein requires 20-30% of its caloric value to break down, effectively boosting your TDEE.
