Novel gene therapy = diet and exercise.
I got the vibe that they were trying to make fat people feel like victims the way they presented the information. We're all aware of the horrible hormonal cascade caused by that shit they were eating. If they wanted to do this better(and IMO, properly), they should have eat healthy food, there is nothing surprising that when you eat lots of chocolate bars, cakes, and other garbage that you are going to get fat. But what if you ate that much of whole "paleo" type foods? I don't think the results would even be in the same ballpark.
