🧬 Why Lean Protein Is So Good for You:

  1. Builds & Repairs Muscle:

    Protein provides essential amino acids needed to rebuild tissue, strengthen muscles, and speed up recovery after workouts.

  2. Boosts Metabolism (TEF Effect):

    Digesting protein burns more calories than carbs or fat (thermic effect of food = up to 30%), helping with fat loss. That’s like doing another workout for the day.

  3. Reduces Hunger & Cravings:

    High-protein meals increase satiety hormones like GLP-1 and PYY, keeping you full longer.

  4. Preserves Muscle in a Calorie Deficit:

    Prevents muscle loss when cutting weight — crucial for staying lean without looking skinny-fat.

  5. Supports Hormone & Immune Function:

    Many lean proteins contain zinc, B12, selenium, iron, and amino acids that aid hormone production and immunity.
