Calculate Basal Metabolic Rate and Total Daily Energy Expenditure for accurate calorie tracking and weight management goals
How to use: BMR (Basal Metabolic Rate) is the calories your body burns at complete rest to maintain vital functions like breathing and circulation. TDEE (Total Daily Energy Expenditure) adds your activity level to BMR for total daily calorie burn. Enter your age, gender, height (cm), and weight (kg). Select your activity level: Sedentary (desk job), Light (exercise 1-3 days/week), Moderate (3-5 days), Active (6-7 days), or Very Active (intense training twice daily). The calculator shows BMR, TDEE, weight loss target (TDEE -500 calories), and weight gain target (TDEE +500 calories). Essential for diet planning and understanding metabolism.
