Low calorie dieting longer life
Both are considered signs of longevity, partly because an earlier study by other researchers found both traits in long-lived people. When a nearby star goes supernova, scientists will be ready. Smashing gold ions creates most swirly fluid ever. Calorie restriction, the scientific name for a regimen high in nutrients but low in calories, is the subject of intense research, and some people have already begun trying it on their own. Faint, distant galaxies may have driven early universe makeover. Remembering Vera Rubin, a trailblazer at the telescope and beyond. The findings lend support to the theory that eating less, long known to prolong life in rats and mice, may do the same for people, by preventing heart disease, cancer, diabetes and other diseases, and by slowing aging. Middling black hole may be hiding in star cluster. Ricin poisoning may one day be treatable with new antidote. Weekend warriors put up a fight against death. Germanium computer chips gain ground on silicon — again. A diet of corn turns wild hamsters into cannibals. Scientists have known for years that when people cut calories and lose weight, the body tries to compensate by slowing its metabolic rate.

A six-month study in 48 people directed by Dr. Intel ISEF students imagine the future at White House Frontiers Conference. There is a Calorie Restriction Society with members all over the world, and its president, Brian M. A low-calorie diet, even in people who are not obese, can lead to changes in metabolism and body chemistry that have been linked to better health and longer life, researchers are reporting. The notion that going hungry could be the fountain of youth has captivated scientists and the public. The diet also led to a drop in thyroid hormones and declines in DNA damage. It was probably preserved by evolution because it saved people from starving to death when food was scarce, but it is the bane of dieters because it means that the more weight they lose, the harder it is to keep reducing. Dual magma plumes fueled volcanic eruptions during final days of dinosaurs. Evan Hadley, director of geriatrics and clinical gerontology at the National Institute on Aging, which paid for the study. How hydras know where to regrow their heads. Ravussin, being published today in The Journal of the American Medical Association, is the first rigorous test of calorie restriction in people who are overweight but not obese. Earlier studies had proved that low-calorie diets could reduce weight and alter metabolism in obese people. DNA points to millennia of stability in East Asian hunter-fisher population. Readers respond to antibiotics, carbon bonds and more. Delaney, estimates that the people experimenting on themselves number in the thousands. Hot nests, not vanishing males, are bigger sea turtle threat. Pectoral sandpipers go the distance, and then some. NYTimes. The slowing is a defensive mechanism to fight weight loss.
