Speaking as a former fat kid myself, I don't think there was any lack of awareness by those around me that I was overweight. I got all the extra attention from the doctors, dietitians, PE teachers and everybody else throughout my youth. I got plenty of advice. The problem was just that the advice itself was all wrong.

So it's all very well for anyone to want to highlight the dangers of obesity and insulin resistance in general, but I don't think that's the real issue. Everybody "knows" that this a problem, the real issue in my view is that not everybody "knows" the solution, least of all our respective policymakers.
