Frequently Asked Questions
What is BMR?
Basal Metabolic Rate is the number of calories your body needs at rest to maintain basic functions like breathing, circulation, and cell production. It accounts for 60-75% of daily calorie burn.
How is BMR different from TDEE?
BMR is calories burned at rest. TDEE (Total Daily Energy Expenditure) is BMR plus calories burned through activity. Multiply BMR by an activity factor to get TDEE.
