I think it's unfair to say that all obese people should be blamed for their weight. It takes a tremendous amount of discipline to lose even a little weight.

I'm sure there are some people who are majorly fat because they eat far too much all the time, but I'm positive the majority does not fall under that category.

I think a bigger factor in american obesity is the relative cheapness of unhealthy food. Oils and sugars and carbohydrates are incredibly inexpensive, so those on low incomes are more likely to consume them, making them more susceptible to obesity and related diseases like diabetes.
