Your BMI is astarting point

BMI is your weight in kilos divided by your height in metres, squared. At 178 cm and 82,5 kg, that is 1,78 squared, which is 3,1684, and 82,5 divided by 3,1684, which is 26,0. That is the whole sum, which is why this calculator can do it inside your browser without sending anything anywhere.

Below 18,5 is underweight. 18,5 to 24,9 is the healthy range. 25,0 to 29,9 is above the healthy range. 30,0 and above is the obesity range. These are the international cut-offs the World Health Organization uses for adults over 18, and they are the same for men and women.

Not well. BMI knows your height and your weight and nothing else, so muscle counts the same as fat. If you train seriously, your BMI will read higher than your body composition warrants. Say so in your assessment and the doctor will take it into account.

Because a single target weight ignores your build, your history and your health, and for some people it is actively harmful to look at. What is useful is the direction of travel and a doctor who knows your case. We would rather give you neither number than give you a wrong one.

The sum runs in your browser. Nothing you type is transmitted unless you fill in the form and press the button yourself, and that form asks for two separate permissions: one for us to handle your health information, and a second, optional one for us to contact you. You can withdraw either at any time.

No. A calculator does not decide that and neither does a number. A Malta-registered doctor reads your assessment, your history and how you feel, and decides what is safe and right for you. Sometimes the answer is no, and when it is, you are told why and where to go instead.

No. Adult BMI bands are read against a chart that does not apply under 18, and bodies that are still growing are measured a different way. If a young person's weight is worrying you, please speak to your family doctor. Carisma Medical is for adults over 18, in Malta.
