Estimate daily calorie needs for weight maintenance, loss, or gain — based on BMR and activity level
Enter your details below to get personalized calorie recommendations using the Mifflin-St Jeor equation (most accurate for general population).
A daily deficit of 500 calories results in ~1 lb of fat loss per week. A surplus of 500 calories leads to ~1 lb gained per week.
BMR = calories burned at complete rest. TDEE = total daily energy expenditure = BMR × activity factor.
