Muscle PreservationHelps maintain lean muscle mass during calorie deficit
Thermic Effect of Food (TEF)Protein has the highest TEF (20-30%) among macronutrients
Amino Acid QualityPrioritize high-quality (complete) proteins like lean meats, dairy, eggs, soy, and complementary plant proteins
Other Macros for Weight LossBalance with complex carbs and healthy fats within a calorie-controlled diet
Comparison for Weight Loss EfficacyHigher protein diets (e.g., 25-35% of total calories) are generally more effective than lower protein diets for weight loss and body composition improvements due to enhanced satiety, muscle retention, and TEF.

Is Dietary Protein an Effective Strategy for Weight Loss?

Adequate dietary protein is highly effective for weight loss. It promotes satiety, helping to reduce overall calorie intake, and crucially aids in preserving lean muscle mass during a calorie deficit, which is vital for maintaining metabolic rate. Furthermore, protein requires more energy to digest and metabolize (higher thermic effect) compared to carbohydrates and fats, slightly increasing daily calorie expenditure.
