At one time or another, you may have found yourself alone in a doctor's examination room and noticed the doctor has left your chart on the desk. You take a small peek, and then are stunned to see that you have been described as ‘obese.’
Obese!?!?
What the doctor was basing this observation upon was actually your Body Mass Index (BMI) calculation. Health professionals use your BMI as an indicator for the amount of fat on your body. The higher the BMI, the greater the risk of some diseases, including high blood pressure, heart disease, stroke, and type 2 diabetes.
The following chart shows what the ranges are for an adult:
BMI Weight Status
Below 18.5 Underweight
18.5 – 24.9 Normal or Healthy Weight
25.0 – 29.9 Overweight
30.0 and Above Obese
Your BMI is calculated based on your height and weight. As an example, a 6'2” tall male who weighs 257 pounds has a BMI of 32.9 (obese).
Now, this formula isn't infallible. That's the height and weight of Arnold Schwarzenegger during his Conan the Barbarian days. Since muscle weighs more than fat, it's possible to be in good condition and have a BMI number showing you are overweight, or to have a good BMI number and still have a high percentage of body fat.
Just remember that when you're contemplating a weight loss regimen, the best thing to do is consult your doctor about the proper diet and exercise program you need for your overall health.
