BMI Calculator

BMI (Body Mass Index) is just a relationship between weight and height. For the vast majority of people, BMI will give a good measure of whether the weight is normal or needs to change. Some populations such as bodybuilders will have a higher BMI because of muscle mass. This tool cannot distinguish between muscle and fat so it is up to you to decide whether you have excess fat or are muscular.

If it detects you're over or underweight, it'll prescribe a daily calorie intake and tell you how long it'll take for you to reach your target.

After you calculate your BMI, visit the diet and exercise forums to find out ways on how you can lose or gain weight to bring your BMI into the normal range.
