Study reveals an ancient gene for lean

Researchers have revealed an antiobesity gene that has apparently been keeping critters lean during times of plenty since ancient times. The gene, first discovered by another team in flies, also keeps worms and mice trim, according to the new report in the September issue of Cell Metabolism, a publication of Cell Press. If the gene works similarly in humans, the findings could lead to a new weapon against our burgeoning waistlines, according to the researchers.
