How this works: BMR uses the Mifflin-St Jeor equation, multiplied by your activity level to get maintenance (TDEE). Weight-change targets assume about 7,700 kcal per kg (3,500 per lb). Results are estimates — everyone's body is different. Goals are never shown below 1,500 kcal (men) or 1,200 kcal (women) without a doctor's supervision. Talk to a healthcare professional before making big changes to your diet.
