About Calorie Calculation
Mifflin-St Jeor Equation
This calculator uses the Mifflin-St Jeor equation (1990), which is considered the most accurate BMR formula according to current scientific research.
Formula:
- Men: BMR = 10 × weight(kg) + 6.25 × height(cm) - 5 × age + 5
- Women: BMR = 10 × weight(kg) + 6.25 × height(cm) - 5 × age - 161
Activity Levels
- Sedentary (1.2): Little or no exercise
- Lightly Active (1.375): Light exercise 1-3 days/week
- Moderately Active (1.55): Moderate exercise 3-5 days/week
- Very Active (1.725): Hard exercise 6-7 days/week
- Extremely Active (1.9): Very hard exercise, physical job
Important Notes
These calculations are estimates. Individual calorie needs vary based on genetics, muscle mass, medical conditions, medications, and other factors. For weight loss, a deficit of 500-1000 calories per day typically results in 0.5-1 kg (1-2 lbs) weight loss per week.
