(A few, very hungry people are trying to see if it works  for humans, too.) But exactly why near-starvation diets make animals  live longer remains unclear. Now MIT&#8217;s Leonard Guarente and colleagues  offer a first step in explaining how two such different processes as  eating and aging could be related in the June 2 online issue of <em>Nature.<\/em> In yeast, longevity is promoted by a gene called SIR2. The researchers  studied the mouse version of this gene called Sirt1 and discovered that  it is activated by scarcity of food. During times of hunger, Sirt1 turns  off receptors that lay down fat deposits, preventing the body from  storing fat and releasing it to be metabolized. So long life through  dieting may involve the body&#8217;s fat-deposition machinery. &#8220;We&#8217;d like to  think this applies to people as well as mice, but we don&#8217;t know for  sure,&#8221; stated Guarente in a press release. &#8220;If we could make this happen  in people, it wouldn&#8217;t just make them live longer; it might also help  prevent diseases of aging, like cancer, diabetes and heart disease.&#8221; <\/span><\/p>\n<h6><em>This news brief appeared in the Discoveries column of the <\/em>Boston Globe&#8217;s<em> Health\/Science section on 6\/08\/2004.<\/em><\/h6>\n","protected":false},"excerpt":{"rendered":"<p>Scientists have long known that calorie-restricted diets can extend the lives of creatures ranging from yeast to fruit flies to mice.
