TDEE (Total Daily Energy Expenditure) Calculator

Calculate your exact Total Daily Energy Expenditure (TDEE) and maintenance calories. While basic calorie calculators rely on a single vague multiplier, this clinical TDEE engine decomposes your total energy burn into its four physiological pillars: Basal Metabolic Rate (BMR), the Thermic Effect of Food (TEF), Non-Exercise Activity Thermogenesis (NEAT) (occupational movement, fidgeting, daily step counts), and Exercise Activity Thermogenesis (EAT) (structured resistance training and cardiovascular exercise). Includes custom deficit and surplus macro targets for body recomposition, cutting, and lean bulking.
