6、ht months. The fat, not surprisingly, has melted away. Butthats not the real reason Apollos and the other participants in the program are eating only three-quarters of what theyused to. The researchers are trying to determine whether restricting food intake can slow the ageing process and extendour

7、life span. I feelbetter and lighter and healthier, says Apollos. But if it could help you live longer, that would be pretty amazing.The idea is counterintuitive:If we eat to live, how can starving ourselves add years to our lives?Yet decades of calorie-restriction studies involving organisms ranging

8、 from microscopic yeast to rats have shown justthat. Last July a long-term study led by researchers at the Universityof Wisconsin, found that calorie restriction seemedto extend the lives of humanlikerhesus mon keys（恒河猴）as well.The hungry primates fell victim to diabetes, heart and brain disease and

9、 cancer much less frequently than their well-fedcounterparts did.Scientists have suspected that calorie restriction could extend the life span of animals since at least 1935, whenresearchers at Cornell University noticed that severely food-restricted lab rats lived twice as long as normal ones andwe

10、re healthier. Other investigators began exploring the idea and learned that the secret is not merely a matter of bodyweight.One theory is that a state of slight hunger acts as a mild but constant stressor that makes an organism stronger andmore resistant to the ills of ageing. Taking in fewer calori

11、es also slowsmetabolism（ 新陳代謝 ）, and some data indicate that humans with a slower metabolism live longer.But even if these theories are correct, simply defining the mechanism is not the sameas identifying the molecularpathways behind it. If researchers could determine those pathways, they might be a

Calorie restriction is prettymuch the only thing out there that we know will not just prevent disease but also extend maximal life span, says Dr.Marc Hellerstein, a nutritio
