Decoding Your Metabolism
Your Basal Metabolic Rate (BMR) is the number of calories your body burns just to stay alive—breathing, circulating blood, and cell production—assuming you did absolutely nothing all day.
BMR vs. TDEE
Do not confuse BMR with TDEE (Total Daily Energy Expenditure).
- BMR: Coma calories (approx 60-70% of total burn).
- TDEE: BMR + Activity Level + Digestion Cost. This is the number you need to eat below to lose weight.
Factors You Control
While age and genetics play a role, Muscle Mass is the biggest controllable factor. Muscle tissue burns more calories at rest than fat tissue. Lifting weights can increase your BMR over time, making it easier to maintain a healthy weight.
