What this means
Your Basal Metabolic Rate is the energy your body needs just to stay alive at rest — breathing, circulation, cell repair. It's the biggest chunk of your daily burn (60–70%) and the foundation for calculating your total needs (TDEE).
Recommendations
- Multiply BMR by an activity factor (1.2–1.9) to estimate your Total Daily Energy Expenditure.
- If you know your body-fat percentage, the Katch–McArdle result is often the most accurate for lean or muscular individuals.
