What is Basal Metabolic Rate (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.
BMR vs TDEE
- BMR: Calories burned at complete rest
- TDEE: BMR + calories from daily activities
- Difference: TDEE is 20-30% higher than BMR
Why BMR Matters
- • Foundation for weight management
- • Helps set realistic calorie goals
- • Guides nutrition planning
- • Tracks metabolic health
BMR typically accounts for 60-75% of your total daily energy expenditure, making it the largest component of your metabolism.
