Basal Metabolic Rate explained
BMR is the energy your body burns at complete rest just keeping you alive — heart, lungs, brain, thermoregulation. It's the floor of your daily calorie needs. Total daily burn is BMR × an activity multiplier, which is what the TDEE Calculator computes.
Turning BMR into a plan
Combine BMR with the Macros Calculator for a protein/carb/fat split, and the BMI Calculator or Body Fat Calculator to track results over weeks.
