I took a quick glance at some of the studies he was involved with. Not enough to say anything with too much certainty. But from what I saw he's often looking at how genetic factors influence the various symptoms of obesity rather than genetics as the root cause of it.  The closest I saw to the standard 'muh genetics' argument was "Identification of pleiotropic genetic effects on obesity and brain anatomy." And even that's pretty much in line with, say, genetic causes of alcoholism. Genetic predisposition rather than predestination.That study suggested some obese people might just be wired to get a bit more happiness when eating something they like while at the same time having issues processing hunger signals. Nothing along the lines of suggesting that someone's going to magically get fat when eating the same things as a normal person.  Basically just suggesting that there might be a genetic link to one person enjoying eating a pie more than another. And a genetic factor in how satiated she might be while eating the pie. Really not the same thing that the average person is talking about when they bring up genetics in the context of weight. And also not suggesting that responsibility for choosing to eat the pie in the first place be taken off fatty.  I don't want to come off as defending the guy. First, because he's fat. Second, because it's nowhere close to uncommon for people to be reasonable in the context of a study and to then go full crazy when speculating on the subjective meaning of the objective findings. But the nature of the research he was involved with seem pretty sound. I went in expecting to get a good laugh out of some ridiculous and horribly designed studies. It's usually the case with this kind of thing. But it seems to be a rare exception this time around.
