MB Calorie Calculator - Version 1.25 MB Free Calorie Calculator is a simple health software with an easy to use interface. The program is designed to calculate the daily calorie intake that your body requires. This is calculated on the basis of your height, weight, age, gender and daily activities. Wanting to lose weight doesn't mean that we stop eating totally. Our body requires calories to perform different functions. We get these calories through the different kinds of food we intake. This software uses the Harris-Benedict equation to determine the daily needed calorie intake. This equation calculates the basal metabolic rate (BMR) and then adjusts it according to the type of daily activity to give the right amount of calories needed.
