The adult BMI risk categories are:
- BMI <18.5 = underweight
- BMI 18.5 to 24.9 = healthy
- BMI 25.0 to 29.9 = overweight
- BMI >30.0 = obese
- BMI >40.0 = morbidly obese
To find out your BMI, divide your weight in pounds by your height in inches multiplied by your height in inches. Take that number and multiply it by 703.
A BMI of less than 18.5 is considered “underweight.” A BMI between 18.5 and 24.9 is considered “normal weight.” A BMI of 25 to 29.9 is considered “overweight.” A BMI of 30 or greater is considered “obese.” Morbid obesity is defined as having a body mass index (BMI) of more than 40. For men that equates to approximately 100 pounds overweight for women, 80 pounds overweight.
