Obesity in the United States has become an issue with adults, it is hard to find time to exercise.
Well... The U.S. has the highest rates in the world. We are a fast food nation.
That is very true. People in the U.S. love the convenience of fast food, but do not make the effort to make healthy meals for themselves.
It's just really convenient. A lot of people don't have time to cook for themselves...so mass-produced garbage it is.
