Altering the Body's Perception of Food May Extend Lifespan

Researchers from the Buck Institute have pinpointed a small molecule, similar to a drug, which changes the body’s attitude towards food within a type of worm known as C. elegans. Researchers used their new knowledge to trick the metabolism within the worm to restrict calories, which in turn increased the lifespan of the animal by 50 percent. Calorie restriction has been shown to extend lifespans as well as healthspans in mice and other simple animals. Researchers would like to use this research to extend this benefits to humans.
