Why are we getting fatter?
So, why are we fat? And getting fatter? Most people would say it's simple: We eat too much and exercise too little. But University of Alabama at Birmingham obesity researcher David B. Allison, Ph.D., says that answer, while valid, may be a little too simple. Allison and colleagues think the more relevant question is this: Why do we eat too much and expend too little energy? And like good detectives, they've set out to identify a suspect, or suspects, that may be contributing to the obesity epidemic. The game, as they say, is afoot. Allison, a professor of biostatistics in the UAB School of Public Health, is senior author on a paper to be published Nov. 24, 2010, in the British journal Proceedings of the Royal Society B. That paper, provocatively titled Canaries in the coal mine: A cross-species analysis of the plurality of obesity epidemics, suggests that the root cause of obesity may be much more complicated than the conventional wisdom — too much food availability, too little opportunity to exercise.
