How Calorie Needs Are Calculated
Uses the Mifflin-St Jeor equation (most accurate for most adults) to calculate BMR, then multiplies by activity factor to get TDEE.
Men: BMR = 10W + 6.25H − 5A + 5
Women: BMR = 10W + 6.25H − 5A − 161
TDEE = BMR × Activity Factor
How accurate is this?
Within 10–15% for most people. Track your weight over 2–3 weeks and adjust calories ±100–200 if the scale isn't responding as expected.
