We have a huge obesity problem here. We also have very high rates of diabetes, heart disease, and anxiety/depression problems. Much of the problem here is cultural in nature, and to fix it, individuals would have to be pro-active in taking care of their health. One of the few incentives that works is for people to have to pay for their healthcare expenses, when you're dealing with a population who loves excess as a lifestyle. Universal coverage in this country would make the problems worse, not better.
