This paragraph demonstrates a widely held, thinly veiled contempt for those with a less fortunate metabolism. This contempt is disgusting, because it is willfully ignorant of all the scientific research that indicates there is a lot more than mere willpower that determines a person's behavior, including eating habits.
As with any religiously held position of superiority, people will continue to justify this contempt with all manner of carefully worded excuses for their desire to feel better than those fat people over there. When does it end?
I think it is no coincidence that the sensational spin the news has put on this story also happens to be a spin that makes their readers feel better about themselves.
What point are you trying to make? That the news should be trying to make people hate themselves more than they already do? Good grief! This research isn't about justifying behavior, it's about identifying the chemical processes driving various metabolic phenomena so they can be controlled and corrected!
You know what about this reseasrch would make an obese reader feel better about himself or herself? It's the fact that, finally, someone has identified a specific mechanism that is causing their problems! It's the hope that comes from having a direction of attack that's more effective than self deprivation.
