BMI Calculator...

Both low and excess body fat levels can pose a serious health risk and increases your risk of death relative to a normal BMI*. In fact some medical practitioners say, that in public health terms, excess weight is more dangerous than being a life-time smoker, chronic drinker, or using banned substances.

Your BMI is a simple measure of the amount of total body fat on your frame. It includes both the essential fat your body needs for effective functioning and any surplus you may be carrying around with you. While BMI can be misleading in individuals who are extremely muscular (e.g. some athletes and people doing manual labour), for most people BMI is a good measure of your total body fat.

So are you under-weight, normal weight, over-weight, or obese?
