And it brought us a BBC article that drops this staggering bombshell: Obesity may be largely genetic.
MY GOD! COULD IT BE?!? Hang on — I need to go call my fat sisters, fat brother, fat aunts, and fat cousins and ask if they’ve ever heard of such a thing.
The article is shite, but the study it describes sounds pretty good: they evaluated 5,000 pairs of identical and fraternal twins, to sort out how much of body size is genetic and how much is environmental. (Fraternal twins are assumed to have similar eating habits and environments, but don’t have exactly the same genes.*) And looky what that turned up:
Their American Journal of Clinical Nutrition study found that differences in body mass index and waist size were 77% governed by genes.
Of course, we must remember — as the article hammers home to the point of completely overshadowing the study’s results — not to take this as AN EXCUSE to just eat whatever we want like grown men and women or something. Obesity being more then 3/4 determined by factors outside one’s control is no reason for people to let themselves get fat!
Thanks to Lindsay for being the first to post about this.
*How interesting that the whole study is predicated on this assumption, when I just recently met a woman who has fraternal twin boys, one of whom is bigger than the other — and she told me the pediatrician is on her ass about that kid’s weight. Because of course the only logical explanation for that would be that she’s overfeeding one kid but giving the other a normal amount of food. As, you know, mothers of twins are totally wont to do. ARE YOU FUCKING KIDDING ME?
