How Protein Isolate Boosts Metabolism Protein isolate is a highly refined form of protein that contains minimal carbs, fats, and lactose, making it a powerful tool for enhancing metabolic function. Here’s how it helps boost metabolism and supports weight management: High Thermic Effect of Food (TEF) Protein has the highest thermic effect among macronutrients , meaning your body burns more calories digesting it compared to fats or carbs. Studies show that 20-30% of protein’s calories are burned during digestion, whereas only 5-10% of carbs and 0-3% of fats are burned this way. Protein isolate, being purer than concentrates, maximizes this effect since it contains almost no extra fats or carbs. Preserves & Builds Lean Muscle Mass Muscle tissue is metabolically active , meaning it burns calories even at rest. Protein isolate provides fast-absorbing amino acids (like leucine) that help: -Prevent muscle breakdown (catabolism) -Support muscle repair and growth More muscl...
