What is A Healthy Weight

To find your Body Mass Index divide your weight in kilograms by your height in meters squared.

Classification BMI Category Risk of Developing Health Problems
Underweight <18.5 Increased
Normal Weight 18.5 - 24.9 Least
Overweight 25.0 - 29.9 Increased
Obese Class I 30.0 - 34.9 High
Obese Class II 35.0 - 39.9 Very High
Obese Class III >=40.0 Extremely High

Another way to check if you have a healthy weight is to measure your waist circumference. Men with a waist circumference greater than 40 inches, and women with a waist circumference greater than 35 inches have an increased risk of developing health problems.
