Normal Weight Obesity

Calculate Your BMI - Standard BMI Calculator:

What is your BMI??

BMI is a ratio of height and weight to help determine the health status of an individual.

Underweight = BMI < 18.5
Normal weight = BMI 18.5-24.9
Overweight = BMI 25-29.9
Obesity = BMI > 30

Although BMI works well in most cases there are limitations to using this method.


The more accurate way to determine health in an individual is looking at body fat percentage.

Women should be 30% body fat or below
Men should be 20% body fat of below

How to determine body fat.
Many methods are used to determine body fat. The most accurate way is to do either underwater weighing or the Bodpod, but these tests can be expensive.

Local gyms or doctors offices typically have other methods such as skin callipers or biological impedance (Tanita scales).

Different scenarios

Have you ever been around that person who is a "twig" but eats a ton of junk and doesn't work out? Their BMI may be in a normal weight range, but guaranteed their body fat is above 30% thus placing them at risk of heart disease, diabetes, and many other co-morbidities. I call this a skinny fat person, or normal weight obesity.

Or what about the body builder who has a lot of muscle mass and very low body fat, but their BMI states that they are obese? It would be silly to call a fit individual obese.

It is important to know where you stand! What is your BMI? What is your body fat percentage? Where do you want to be?

What is one change that you would like to make in your diet/exercise pattern to improve your health??
