How this works

BMR (Basal Metabolic Rate) is the calories your body burns just to keep you alive — breathing, circulation, organ function — with zero movement.

TDEE (Total Daily Energy Expenditure) multiplies your BMR by your activity level. Eat at TDEE to maintain weight. Creating a 500 cal/day deficit produces roughly 1 lb/week of fat loss.

Formula: Mifflin-St Jeor equation (2005, most accurate for most adults). Macro split is a common starting point — adjust to your goals and consult a dietitian for medical needs.
