Obesity and Type 2, my thoughts:
The obesity is a symptom or a processing disorder. Therefore, blaming the obesity for the diabetes is the wrong way round. Many slim people have the same processing disorder, but it comes on quickly and steeply, on before the slow annual weight gain of the typical type 2 (around 80% of them).
The NHS and mainstream medical treatment to cut fats and increase/focus on carbs exacerbates the processing disorder, leading to more weight gain and/or feeling ill
So the obesity blaming should stop, in my view. I see the current situation of blaming the overweight or those who had a carb heavy diet as like blaming the people who were encouraged by their doctors to smoke, and then blamed for getting lung cancer.
Thanks to the unfortunate consequences we now see from those who have had over 30 years of the wrong advice, we are able to learn from these human guinea pigs and change course. Unfortunately many of the guinea pigs are left with serious conditions due to the wrong health care, and those of us who have been undiagnosed with insulin resistance for years also have collateral damage, some of which is hard to reverse, although we can stop the rot.
So yes, 80% of type 2 diabetics may be obese at diagnosis, but the follow on blaming and shaming and pointing to them as greedy pigs who deserve what they get for their greed, by the media and medical profession and even some on here occasionally, is often not true, and is unfair and should be challenged whenever possible.
The concept that type 2's are overweight at diagnosis, therefore they have overeaten themselves into this is not right. Its the wrong conclusion to the evidence.
