> And then....what? Well from a macro scale, I think some things get better -- overall population health goes up, obesity/fat-related diseases go down. But does heart disease? I wonder if it goes up -- if everyone looks like they've wanted by shutting off the body's fat stores, does the motivation to do cardio go down for some people?

I don't understand the tendency some people have to find a negative in something that is mostly positive. It doesn't make sense to me. Sure, some negatives MIGHT happen, but are you really trying to justify not moving forward with this research because some people might use it as an excuse to be lazy? Really?

What if everyone being the weight they want gives them more self-confidence, which gives them reason to get out more? What if there's less depression? What if there are fewer people with diabetes? There's potential to have some really great effects on the population at large here.
