Understanding BMR vs. TDEE
To manage your weight effectively, you need to understand two key numbers:
- BMR (Basal Metabolic Rate): The calories your body burns just to stay alive (breathing, circulating blood) while at complete rest.
- TDEE (Total Daily Energy Expenditure): Your BMR plus the calories burned through movement, work, and exercise.
The 3,500 Calorie Rule
Generally, one pound of body fat contains roughly 3,500 calories. Therefore, to lose 1 pound per week, you typically need a deficit of 500 calories per day (500 x 7 = 3,500).
