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.

Calorie: A unit of energy. Food calories (kilocalories) measure the energy content of food.

Deficit: Consuming fewer calories than you burn, resulting in weight loss.

Surplus: Consuming more calories than you burn, resulting in weight gain.

Maintenance: Consuming the same number of calories you burn, maintaining current weight.

How the Calculation Works

This calculator uses the Mifflin-St Jeor Equation:

For Men:

BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age) + 5

For Women:

BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age) - 161

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
