Reuters reports that an Italian researcher has linked a gene (charmingly named DD) to abnormal weight gain in men. And it’s widespread – about 40% of the population (I’m not clear which population) has it. It’s not as big a deal as made out, however when you read that 52 percent of carriers are overweight as compared to 44% of non carriers. That’s the problem with reading the last part of an article as opposed to just the headline – the headline is always an attention grabber, staking out the most extreme position, and the real meaning is buried at the end of the article.
