BMR (Basal Metabolic Rate)
Definition: The number of calories your body burns at complete rest just to keep you alive — breathing, heartbeat, brain function. BMR typically accounts for 60-70% of your TDEE.
Detailed Explanation
Basal Metabolic Rate (BMR) is the caloric cost of keeping your body alive at complete rest. It covers involuntary functions like breathing, circulating blood, cellular repair, temperature regulation, and brain activity.
Practical Application & Guide
Your BMR represents the floor of your energy needs. Aggressive diets should rarely drop below your BMR, as doing so can trigger severe metabolic downregulation, muscle loss, and chronic fatigue.
Common Pitfalls & Mistakes
Confusing BMR with TDEE. BMR does not include any movement, walking, or digestion; it is purely the cost of staying alive in a resting state.
