Weight Loss Calorie Calculator

Weight Loss Calorie Calculator allows you to calculate how many calories you should eat a day in order to lose a certain amount of weight by a given time period.

Weight Loss Calorie Calculator is based on the Mifflin-St Jeor equation. With this equation, the Basal Metabolic Rate (BMR) is calculated by using the following formula:

BMR = 10 * weight(kg) + 6.25 * height(cm) - 5 * age(y) + 5 (male)
BMR = 10 * weight(kg) + 6.25 * height(cm) - 5 * age(y) - 161 (female).

The calories needed to maintain your weight equal to the BMR value, multiplied by an activity level factor. To loss 1 pound, you will need to shave 500 calories from your daily menu.

The American College of Sports Medicine recommends a minimum of 1200 calories per day for females and 1800 calories per day for males.
