Overweight people participating in this study who cut their calories by 25 percent for six months have reduced insulin levels and core body temperature (deep inside the body) - two markers for which lower levels have been associated with increased longevity in humans.The results of the study are published in the Journal of the American Medical Association; April 2006.
