I am not really sure what food addiction is, and I'm not sure I would put it in here. I think what I would put in its place would be excessively busy schedules.
So then I would write a thesis statement like this: In the United States today, we have an epidemic of childhood obesity.
Who needs to be educated on child obesity, the child or the parent?
These are points to ponder when it comes to child obesity.
Your thesis statement should include your reasons for supporting your beliefs.
