FAQ
What is BMR?
Basal Metabolic Rate — the calories your body needs for breathing, digestion, and blood circulation even if you stayed in bed all day.
What's the difference between BMR and TDEE?
BMR is just resting calories. TDEE (Total Daily Energy Expenditure) adds calories from daily activities/exercise on top — TDEE is always higher than BMR.
Which formula is used?
The Mifflin-St Jeor formula — considered more accurate than Harris-Benedict, and the one dietitians recommend today.
