About BMR
Basal Metabolic Rate (BMR) is the number of calories your body needs to maintain basic physiological functions while at rest. This includes breathing, circulation, cell production, nutrient processing, and protein synthesis.
Activity Level Multipliers:
- Sedentary (little/no exercise): BMR × 1.2
- Light activity (light exercise 1-3 days/week): BMR × 1.375
- Moderate activity (moderate exercise 3-5 days/week): BMR × 1.55
- High activity (hard exercise 6-7 days/week): BMR × 1.725
- Very high activity (very hard exercise, physical job): BMR × 1.9
