- : "Being fat has long been seen as a personal problem, fixed only by struggling against the proliferation of fast food restaurants, unlucky genes, and a sedentary life. more stories like this * Tufts study: Drug trials are getting longer, harder * College hopefuls try the creative approach, but gimmicks rarely work * Elizabeth Lawrence, 74, scholar of human-animal relations * Correction: Financial aid story * As wealthy colleges eliminate loans, others feel pressure to compete * But could something in the environment also be making Americans fat in epidemic numbers? Animal studies in recent years raise the possibility that prenatal exposure to minuscule amounts of common chemicals - found in everything from baby bottles to toys - could predispose a body to a life of weight gain. The chemicals, known as endocrine disrupters, mimic natural hormones that help regulate, for example, how many fat cells a body makes and how much fat to store in them. These findings have led some scientists to put forth a provocative argument: They say diet and too little exercise clearly are key reasons for the worldwide rise in obesity in the past 20 years, but they may not be the only ones. Food intake and exercise just haven't changed that much in that period, they argue. And while genetics obviously play a role - just think of someone you know who can eat three Big Macs a day and never gain an ounce - these researchers say it would be impossible to see such widespread genetic change in just two decades, giving them more reason to suspect the environment. "This is a really new area . . . but from multiple labs on multiple levels we are getting preliminary data that all say the same thing: Chemicals can play a role," said Jerry Heindel, a program administrator for the National Institute of Environmental Health Sciences. "We know that nutrition and exercise are very, very important, but underlying that could be environmental exposures during development that alter your physiology, including how you respond to food and exercise.""
