But don't you think that it's better to make the changes to prevent obesity rather than focus so much on a cure for after?

I don't have a problem with a cure only if it doesn't reduce the focus and effort on prevention.

There has to be a reason why so many more people are obese today than decades ago. I refuse to believe we can't find out why and make changes to reverse it.

But if it's so easy to cure, will enough people care about figuring out how to prevent it?
