Frequently asked questions
What's the difference between BMR and TDEE?
BMR is calories burned at complete rest — just to keep organs functioning. TDEE adds the energy used for all daily movement and exercise. Most people's TDEE is 1.4-1.8× their BMR. TDEE is the number that actually matters for nutrition planning.
How accurate is TDEE?
Within 10-15% for most people. The main uncertainty is the activity multiplier — people consistently underestimate their sedentary time and overestimate their exercise intensity. Track calories for a week at your TDEE estimate and adjust if weight changes unexpectedly.
