Why Protein Matters for Weight Loss

Protein is the most important macronutrient for weight loss. It preserves muscle mass, increases satiety, and boosts metabolism through the thermic effect of food.
Research shows: Protein intake of 1.6-2.4g/kg body weight is optimal for muscle preservation during weight loss.
Key Benefits of High Protein During a Deficit
- Preserves muscle: Prevents muscle breakdown during calorie restriction
- Increases satiety: Keeps you feeling full longer than carbs or fats
- Boosts metabolism: Burns 20-35% of calories just through digestion
- Improves body composition: More fat loss, less muscle loss
