Basal Metabolic Rate

FAQ
- What formula does this use?
- The Mifflin-St Jeor equation: for men, BMR = 10 * kg + 6.25 * cm - 5 * age + 5; for women, BMR = 10 * kg + 6.25 * cm - 5 * age - 161. It is widely considered the most accurate resting metabolic rate predictor for the general population.
- What does BMR mean, and how do I use it?
- Basal Metabolic Rate is the number of calories your body needs at complete rest just to maintain basic functions. Multiply BMR by an activity factor (1.2 for sedentary, up to 1.9 for very active) to estimate your Total Daily Energy Expenditure (TDEE).
