Risk factors are, by definition, factors that statistically increase your risk of getting some disease. My point was that having a risk factor doesn't guarantee that you'll get some disease, and not having that factor doesn't guarantee that you'll never get it.
If you look at populations, then it's clear that people who are overweight are more apt to get diabetes. Some people think that the insulin resistance comes first and causes the overweight. Others think the opposite.
But when you look at an individual, then risk factors aren't as accurate. One person might have a lot of risk factors and never get the diseases, and another would be risk-factor-free and get the diseases.
One problem is that some physicians wouldn't do a BG test in a thin person who exercised because they would have low risk factors.
Wow, I mis-called most of those! But I'm still wincing about the woman who scored 9+ but won't go back to be retested unless the tiredness continues, and the one who was told she was OK with a reading of 3.1!
