What Is BMR?
Basal Metabolic Rate is the number of calories your body needs at complete rest to maintain basic functions like breathing and circulation. Men: BMR = 10*weight(kg) + 6.25*height(cm) - 5*age - 5. Women: BMR = 10*weight(kg) + 6.25*height(cm) - 5*age - 161.
Using Your BMR
BMR forms the foundation of calorie planning. Your actual daily needs are higher depending on activity level. Never eat below your BMR for extended periods as it can slow metabolism.
