Calorie Calculator

The Calorie Calculator helps estimate daily calorie target, providing simple guidelines for weight gain or loss. The results suggest daily calorie estimates to guide maintenance, weight loss, or gain at a chosen rate.

These results should always be discussed with a nutritionist or healthcare provider for personalized advice and safety.

We never recommend less than 1200 kilocalories per day.

The Calorie Calculator is based on the Mifflin-St Jeor equation, the latest (1990) revision of the Harris-Benedict Equation.

For men:


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

For women:


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

The resulting value is then modified according to your activily level:

AMR = BMR * Activity Factor

where AMR stands for active metabolic rate and Activity Factor is:

1.2 for Sedentary

1.375 for Light

1.55 for Moderate

1.725 for Active

1.9 for Very Active

Finally, the resutls are presented as daily calorie target for maintaining, losing (-500kcal) or gaining (+500kcal) weight.
