  • BMI 18.5 to 24.9 = healthy

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.
