Frequently Asked Questions
BMR (Basal Metabolic Rate) is the number of calories your body needs to perform basic life-sustaining functions like breathing, circulation, and cell production while at rest.
The Mifflin-St Jeor equation is generally considered more accurate for modern populations. Harris-Benedict tends to slightly overestimate.
BMR is calories at rest only. TDEE includes BMR plus calories burned through activity. Use our Calorie Calculator for TDEE.
