How to Use the Calorie Calculator

How It Calculates the Results
This calculator uses the Mifflin-St Jeor Equation to compute the Basal Metabolic Rate (BMR). BMR is the number of calories your body needs at rest to maintain vital functions. The formula is:
- For men: BMR = 10 * weight + 6.25 * height – 5 * age + 5
- For women: BMR = 10 * weight + 6.25 * height – 5 * age – 161
This BMR value is then multiplied by the selected activity level to estimate the total daily caloric needs. The activity levels have the following multipliers:
- Sedentary (little or no exercise): 1.2
- Lightly active (light exercise/sports 1-3 days/week): 1.375
- Moderately active (moderate exercise/sports 3-5 days/week): 1.55
- Very active (hard exercise/sports 6-7 days a week): 1.725
- Super active (very hard exercise/sports & physical job): 1.9
Limitations
This calculator gives an estimate of daily caloric needs. Actual caloric requirements may vary based on various factors including, but not limited to, muscle mass, overall health, and specific metabolic conditions. For personalized advice, consult with a healthcare or nutrition professional.
