Julie -- This is an interesting and thoughtful piece. One thing I would encourage you to think critically about, however, is the sensationalization of the "obesity epidemic." You include obesity in your list of ailments with heart disease and diabetes. There has been little to show a definitive link between fatness and ill health, unless there are other indicators such as high blood pressure, high cholesterol, high blood sugar or similar. A fat person with excellent blood panels is not necessarily in any better or worse health than a thin person with excellent blood panels. You may want to look into Health at Every Size (http://en.wikipedia.org/wiki/Health_at_Every_Size) -- I think focusing more on health than size or weight is a good strategy for everyone, and would help work against a lot of the size-based shaming that people confront.
