Why is obesity in the United State an issue when it kills people????

People avoid certain drugs because they "know" it kills them. People avoid guns, gangs because they "know" you can get killed. People "sometimes" avoid drinking and driving because they "know" it kills. So why don't people regulate their diets to avoid obesity when they "know" it kills???? Millions of people are dying because they are overweight. Why is that? Asking callers why they believe this is, what can be done about it, how they have helped others, and more.
