  • A BMI from 18.5 to 24.9 kg/m2 is considered normal.
  • Adults with a BMI of 25 to 29.9 kg/m2 are considered overweight. There are exceptions. Some people in this group, such as athletes, may not have too much fat, and may not have an increased risk of health problems due to their weight.
  • Adults with a BMI of 30 to 39.9 kg/m2 are considered obese.
  • Adults with a BMI greater than or equal to 40 kg/m2 are considered extremely obese.
  • Anyone more than 100 pounds overweight is considered morbidly obese.
