The new study aimed at improving knowledge of the metabolic effects of caloric restriction suggests that some of the important beneficial changes may relate to the activities of the symbiotic bacteria that live in the intestinal tract. Those microbes produce a range of biochemicals that may influence disease processes and alter energy metabolism in the host organism. Researchers paired 24 dogs, with one dog in each pair given 25 percent less food than the other. Those with a restricted intake of calories lived, on average, about 1.8 years longer than those with a greater intake. Researchers noted that the studys main goal was to help develop diets that keep pet animals alive and healthy for as long as possible, but that the findings may be relevant to human dietary changes and obesity.
