That's a very good question and, in fact, one scientist we interviewed on the podcast a few years ago, Professor Steve O'Rahilly who works on obesity and diabetes at Cambridge University, said much the same. His point was that becoming fat in the present world environment is an inevitably and therefore studying the average fat person to understand obesity is not the way to find the answer. Instead, he said, we should be looking at the "normal" people who don't get fat, because clearly they have the ability to remain at the normal weight despite the obesogenic influence of their environment; genetically, therefore, they may have more to tell us about the mechanisms of weight gain and how to reverse or prevent it.
