What Is a High-Protein Diet?
A high-protein diet emphasizes foods that are rich in protein while balancing carbohydrates and fats. Protein is a macronutrient essential for muscle repair, hormone production, and metabolic health.
-
Recommended intake: For active adults, 1.2–2.2 grams of protein per kilogram of body weight daily is generally suggested.
-
Sources: Lean meats, poultry, fish, eggs, dairy, legumes, nuts, and protein powders.
How Protein Supports Lean Muscle
Protein provides amino acids, the building blocks of muscle tissue. When combined with resistance training, it helps:
-
Repair muscle fibers after workouts.
-
Promote muscle growth through protein synthesis.
-
Prevent muscle loss during calorie restriction or aging.

Fat-Burning Benefits of a High-Protein Diet
1. Increased Thermogenesis
Digesting protein burns more calories compared to carbs or fats, a phenomenon called the thermic effect of food (TEF).
2. Appetite Control
Protein-rich meals increase satiety, reducing cravings and total calorie intake throughout the day.
3. Preserves Lean Mass During Weight Loss
Unlike low-protein diets, high-protein diets help maintain muscle while promoting fat loss, which enhances body composition.
Best High-Protein Foods
Lean Meats
Chicken, turkey, and lean cuts of beef provide high-quality protein with minimal fat.
Fish
Salmon, tuna, and cod are protein-rich and contain healthy omega-3 fatty acids.
Eggs
Whole eggs and egg whites support muscle repair and nutrient absorption.
Dairy
Greek yogurt, cottage cheese, and skim milk are excellent slow-digesting protein sources.
Plant-Based Options
Legumes, tofu, tempeh, and quinoa are ideal for vegetarians and vegans seeking protein.
