What is BMR (Basal Metabolic Rate)?
Your Basal Metabolic Rate (BMR) is the number of calories your body burns while at rest to maintain essential functions like breathing, circulation, and cell production. It represents the minimum energy required to keep your body functioning.
BMR Calculation Methods:
- Mifflin-St Jeor Formula: Most accurate for general population
- Harris-Benedict Formula: Older but still widely used
- Katch-McArdle Formula: Uses lean body mass (most accurate for athletes)
Factors Affecting BMR:
- Age: BMR decreases with age due to loss of muscle mass
- Gender: Men generally have higher BMR due to more muscle mass
- Body Composition: More muscle = higher BMR
- Genetics: Some people naturally have faster metabolism
- Hormones: Thyroid function significantly affects BMR
TDEE (Total Daily Energy Expenditure):
- Sedentary: BMR × 1.2 (little or no exercise)
- Lightly Active: BMR × 1.375 (1-3 days/week)
- Moderately Active: BMR × 1.55 (3-5 days/week)
- Very Active: BMR × 1.725 (6-7 days/week)
- Extra Active: BMR × 1.9 (athletes, physical jobs)
