Protein is the only macronutrient that the body struggles to store as fat. It also has the highest **Thermic Effect of Food (TEF)**—meaning your body burns about 20–30% of the calories in protein just to digest it.
#### The Satiety Mechanism
Protein triggers the release of PYY and GLP-1 (fullness hormones) while suppressing Ghrelin (the hunger hormone). This makes high-protein diets the most sustainable “hack” for long-term weight maintenance.
#### The Implementation
1. **The 30g Breakfast Anchor:** Starting the day with 30g of protein stabilizes blood sugar and prevents the “afternoon slump.”
2. **Distribution over Concentration:** Research suggests that spreading protein intake across 3–4 meals is superior for muscle protein synthesis than one large meal.
3. **Calculate Your Target:** Use our [Macro Calculator](/macro-calculator/) to determine your specific protein floor based on your lean mass.
