âšī¸ About BMR & TDEE
BMR (Basal Metabolic Rate) is the number of calories your body needs at complete rest to maintain basic functions like breathing, circulation, and cell production.
TDEE (Total Daily Energy Expenditure) is your BMR multiplied by an activity factor, representing total calories burned per day including exercise and daily activities.
The Mifflin-St Jeor equation is considered the most accurate for most people. Katch-McArdle is preferred if you know your body fat percentage.
