This calculation shows your Basal Metabolic Rate and Total Daily Energy Expenditure based on your inputs.
Male, 30 years old, 180 lbs, 6'0", active
BMR: 1900 calories, TDEE: 2800 calories
Your BMR and TDEE reflect a higher caloric need due to increased activity levels.
Female, 40 years old, 130 lbs, 5'4", sedentary
BMR: 1300 calories, TDEE: 1600 calories
Lower activity levels result in a decreased total caloric expenditure.
