According To My Medical Records, I'm Obese

I just made an appointment with an orthopedist because I'm experiencing awful pain from what I believe is a strained piriformis. That's a nice way of saying "pain in the ass".

(Yeah, I know I need a haircut. Ease up a bit, please.)

And I had to go online to update my info in their patient portal. What did I find out? OMG, I'm obese! I know I'm bulking right now, but come on!

Well, according to the records my Body Mass Index (BMI) is approx 31.

Your BMI is a way of finding out if your weight is putting your health at risk and is used by health professionals around the world. It is based on your height and weight and can be worked out by taking your weight in kilograms and dividing it by your height (in metres) squared. For any height there is a range of healthy weights. BMI is classified in the following way:

  • A BMI of less than 18.5 kg/m2 indicates you are underweight. You may need to gain weight.

  • If your BMI is 19 to 24.9 kg/m2, you're are a healthy weight, and should aim to stay that way.

  • A BMI of 25 to 29 kg/m2 is defined as overweight. It's a good idea to lose some weight for your health's sake, or at least aim to prevent further weight gain.

  • A BMI of over 30 kg/m2 is defined as obese and means your health is at risk. Losing weight will improve your health.


Your BMI is not always a good reflection of body composition. A very muscular person might have a high BMI when in fact their body fat is at a healthy level. Remember: muscle weighs more than fat. On average, the density of fat is 0.9g/ml. The density of muscle is 1.1 g/ml. Using the averages, 1 liter of muscle weighs 1.06 kg or 2.3 lbs., while 1 liter of fat weighs .9 kg, or 1.98 lbs.

Fitness is not about a number, it's about taking care of yourself. And if you are overweight, there's no better time to start treating your body well than right now. If you're not sure how to begin, check out my article on how to start.

You've only got one body and if you treat your body well it'll last you a lifetime.
