Abbreviations Explained
BMR (Basal Metabolic Rate): The number of calories your body burns at rest to maintain basic life functions like breathing and circulation.
TDEE (Total Daily Energy Expenditure): Total calories burned per day including BMR plus physical activity.

How the Calculation Works
This calculator uses the Mifflin-St Jeor Equation:
For Men:
For Women:
Activity Multipliers:
- Sedentary (little/no exercise): BMR × 1.2
- Lightly active (1-3 days/week): BMR × 1.375
- Moderately active (3-5 days/week): BMR × 1.55
- Very active (6-7 days/week): BMR × 1.725
- Extremely active (physical job + exercise): BMR × 1.9
Example: 30-year-old woman, 150 lbs (68 kg), 5'5" (165 cm), moderately active:
• BMR = (10 × 68) + (6.25 × 165) - (5 × 30) - 161 = 1,431 calories
• TDEE = 1,431 × 1.55 = 2,218 calories/day
