Why Protein Matters
Muscle Growth and Repair
Protein provides the amino acids your body needs to build and repair muscle tissue. Whether you are strength training, recovering from exercise, or simply maintaining lean mass, adequate protein is essential.
Weight Management
Protein is the most satiating macronutrient. Higher protein intake helps you feel fuller longer, reduces cravings, and preserves muscle during a calorie deficit, making weight loss more sustainable.
Metabolic Health
Protein has the highest thermic effect of food: your body uses 20–30% of protein calories just digesting it. Adequate protein also supports immune function, enzyme production, and hormone regulation.
Healthy Aging
As we age, our muscles become less responsive to protein. Higher intakes (1.0–1.2+ g/kg) help counteract age-related muscle loss, support bone density, and maintain functional independence.
