What is BMR?
Basal Metabolic Rate (BMR) is the number of calories your body needs to maintain essential functions at rest. Use BMR to estimate total calorie needs and build nutrition plans.
- Mifflin-St Jeor is considered the most accurate for most people.
- Katch-McArdle uses lean body mass when body fat percentage is known.
- BMR does not include activity or exercise calories.
