What we liked about this particular calculator is that it not only does the math for you, but it also displays in a colored, user-friendly way the various categories of bmi (underweight, normal, overweight, obesity class I-III). In addition, once you have calculated your bmi, you can slide the little gray indicator bar up and down and the weight changes accordingly.

What If My BMI Is Over 25?
In most people, a bmi over 25 signifies overweight, and a bmi over 30 denotes obesity. There are some notable exceptions, though.

As a matter of fact, your body fat percentage is likely to be significantly lower than in sedentary people.

. This being said though, keep in mind that for the vast majority of people, bmi is a good indicator of their weight status. Together with other indicators, doctors use bmi to estimate a person's risk of developing many diseases, including diabetes, cancer, cardiovascular disease, etc.
