How it's calculated
BMR = 10·kg + 6.25·cm − 5·age + s, TDEE = BMR × activity (s = +5 male, −161 female)
kg = weight, cm = height, age = years, s = sex constant, activity = 1.2–1.9. Mifflin–St Jeor BMR; TDEE = maintenance calories. Cut target = TDEE − 500 kcal for roughly 0.45 kg/week loss.
Common questions
What are maintenance calories?
They are the daily calories that keep your weight steady, also called your total daily energy expenditure or TDEE.
How big should a calorie deficit be to lose weight?
A 500-calorie daily deficit aims at about 1 pound of fat loss per week, which is the common starting point this tool shows.
