Basal Metabolic Rate (BMR) is the energy your body uses at rest to run core functions.
| Equation | Men | Women |
|---|---|---|
| Mifflin–St Jeor | 10×kg + 6.25×cm − 5×age + 5 | 10×kg + 6.25×cm − 5×age − 161 |
An 80 kg, 180 cm, 35-year-old man: 10×80 + 6.25×180 − 5×35 + 5 = 800 + 1125 − 175 + 5 = 1,755 kcal/day.
BMR is the largest part of TDEE for most people. Use it as a base, not a calorie target by itself.
Resting Metabolic Rate (RMR) is the energy burned at rest while awake in a relaxed state.
Total Daily Energy Expenditure (TDEE) is the sum of calories you burn each day.
Maintenance Calories are the intake that keeps body weight stable over time.
