Understanding Your BMR
- BMR (Basal Metabolic Rate) is the number of calories your body burns at complete rest
- It accounts for 60-75% of your total daily energy expenditure
- TDEE (Total Daily Energy Expenditure) = BMR × Activity Multiplier
- Factors affecting BMR: age, gender, muscle mass, genetics, and hormones
- Use TDEE to determine calories for weight loss, maintenance, or gain
