Have you ever seen those people who eat junk food, but yet maintain an otherwise healthy-looking figure? We’ll those people might not be so safe after all. According to a recent study conducted in 2008, If you are at a normal weight, (as defined by a normal BMI), but have a high body fat percentage, you are at a higher risk of type 2 diabetes, metabolic syndrome, and cardiovascular disease (1).
I’ve observed this first hand in the diabetes prevention program with myself. I technically qualified to be in our program getting the lowest score possible to be diagnosed as pre-diabetes, 100. But let’s not forget, my blood sugars were elevated and this was significant. I ate very well (and my own trainer could testify to that), had a “perfect” BMI of 25, exercised, and maintained an overall healthy lifestyle. While my solution to lower my blood sugars was different than most other’s, it still required that I check my blood sugar’s frequently which I did.
The most important thing to take away from this is that if you do not get checked for diabetes, metabolic syndrome, and cardiovascular disease, you have no idea if you are truly healthy. These diseases are independent of how fit you appear, what your weight is, or even what your body fat percentage is. However, if your body fat percentage is elevated, then you should get checked.
What tests should you ask your doctor for (or your fitness trainer for)? First, get your body fat percentage checked. For men, if your body fat percentage is 23.1% or higher, and for women, if your body fat percentage is higher than 33.3%, then you need further testing. These tests should include a physical, full lipid panel, fasting blood sugar test, and vitamin D check. If you are deficient or elevated on any of these tests, don’t forget that exercise has been found to help in all of these (except for vitamin D when done indoors).
