TDEE Calculator (Total Daily Energy Expenditure)
Your Total Daily Energy Expenditure (TDEE) is the total number of calories you burn each day, including your basal metabolism and physical activity. Knowing your TDEE is the foundation for any diet or nutrition plan.
TDEE is calculated by first determining your Basal Metabolic Rate (BMR) using the Mifflin-St Jeor equation, then multiplying it by an activity factor. The activity factors range from 1.2 (sedentary) to 1.9 (extra active). To lose weight, you need to eat fewer calories than your TDEE; to gain weight, you need to eat more. A moderate deficit of 500 calories per day will result in approximately 0.5 kg (1 lb) of weight loss per week. It is generally not recommended to eat below your BMR.
