This calorie calculator is based on the Mifflin - St Jeor equation. With this equation, the Basal Metabolic Rate (BMR) can be calculated with the following formula.
for man: BMR = 10 * weight(kg) + 6.25 * height(cm) - 5 * age(y) + 5
for woman: BMR = 10 * weight(kg) + 6.25 * height(cm) - 5 * age(y) - 161
The calories needed to maintain your weight equal to the BMR value multiply by an activity factor. To loss 1 lb or 0.5kg per week, you will need to take 500 calories off from your maintenance calorie needs everyday.
The best way to loss weight is by exercise rather than to starve yourself. Try not to lower your calorie intake by more than 1000 calories below maintenance a day and try to lower your calorie intake gradually.
The results of this calorie calculator are an estimation based on average.
