BMI Calculator

I have included the BMI calculator as some people like to use it to gauge their health, the BMI formula is so simple, it’s easy to use by just about everyone. However, it’s that simplicity that makes it inaccurate because it only takes into account your height and weight. Whether you’re overweight or not requires much more information than just your height and weight.

Here are all the things that this BMI formula may get wrong:

  • How Much Muscle You Have: The more you have the higher your BMI will be, even though you may be healthy
  • Frame Size: A person with a big frame will have a higher BMI, although he or she may still be healthy
  • Gender: At the same BMI, women will usually have more body fat than men
  • Age: At the same BMI, an older person will usually have more fat than younger adults
  • If You’re an Athlete: At the same BMI, athletes will usually have less body fat than people who aren’t athletes.

****If you are very muscular, pregnant or have a large frame your calculation may show you as overweight or obese, even when you are not*****
