BMI measures weight in relation to height. The BMI ranges shown above are for adults. They are not exact ranges of healthy and unhealthy weights. However, they show that health risk increases at higher levels of overweight and obesity. Even within the healthy BMI range, weight gains can carry health risks for adults.
Directions: Find your weight on the bottom of the graph. Go straight up from that point until you come to the line that matches your height. Then look to find your weight group.
Healthy Weight BMI from 18.5 up to 25 refers to a healthy weight.
Overweight BMI from 25 up to 30 refers to overweight.
Obese BMI 30 or higher refers to obesity. Obese persons are also overweight.

I am actually working on a paper to show how BMI is a poor predictor of body fatness.
LOL (No offense Mari!). The problem with the BMI is that it fails to differentiate fat from lean muscle mass. Therefore a person who is heavy because he/she has a lot of muscle would fall in the overweight category based on BMI alone. I'm actually one of them, my BMI is probably around 26-27, and even though I do carry some extra fat pounds, just my lean weight (muscle, bone and water) is over 135 pounds. Now if you look at most celebrities that are 5'7'' like I am, most of them will weight 120 pounds or less of TOTAL weight (lean+ fat), which is a shame!
