The gene research is fascinating. Traits that had survival value when food was scarce, now work against us if we're not aware and don't take steps to compensate for them. A preference for fat and sugar, in a natural world (were such resources are scarce) would have survival value. In the modern world, not so much.
I don't think that understanding the genetic factors absolve people from responsibility, but I don't think most people would expect it to. Rather knowing more about the genes and how they work, would help us design better and more effective strategies. It might be the first steps towards developing truly individualized weight loss strategies, or even diagnosing potential issues before they are a problem.
