About BMR
Basal Metabolic Rate (BMR) represents the minimum amount of energy needed to keep your body functioning at rest. This includes breathing, circulation, cell production, nutrient processing, and maintaining body temperature.
BMR Formulas:
- Mifflin-St Jeor: Considered the most accurate for most people
- Harris-Benedict: Traditional formula, slightly less accurate than Mifflin-St Jeor
- Katch-McArdle: Accounts for lean body mass, useful for athletes
Uses of BMR:
- Planning weight loss or weight gain goals
- Understanding your minimum nutritional needs
- Setting a baseline for caloric intake
- Tracking metabolic health over time
Good to know:
Your BMR is influenced by factors like age, gender, height, weight, body composition, genetics, hormonal factors, and environmental temperature. To determine your total daily calorie needs, you'll need to multiply your BMR by an activity factor.
