I never would have thoughht of that, but I didn't wrie the title. /s
And, diabetes doesn't always necessarily have anything to do with obesity.
How many of those with type 2 diabetes and normal weight are really latent autoimmune diabetes in adults and insulin dependent? Whether it's slightly overweight or morbid obesity, the typical type 2 is not skinny.
I know you uised the word "typical", but I'm going to quibble a bit with you over this. IMO (and I'm no expert), the medical folks are still trying to figure out how the body works. Classifying someone as a "typical diabetic" isn't necessarily a valid observation.
Case in point, I'm a type 2 diabetic. There is no history of diabetes in my family and I have never been morbidly obese. So, how did I become a diabetic? I, along with tens of thousands of other guys, was exposed to Agent Orange in Vietnam. And, diabetes is at the lower end of the diserases associated with Agent Orange.
I make this point because we have a belief in this country that those who are diabetic probably over ate junk food or we eat a lot of sugar. While those are "typical" causes of type 2 diabetes, there are other factors that play a part. As you noted one-third of obese people will never develop diabetes.
From all of my discusions with my doctors and clinicians over the years, I know this - we still have a long way to go to really understand the human body and why things happen the way they do. Until that day arrives, it is, again IMO, a bit early to try to fit people into specific categories based on common factors. We aren't there yet.
