可以活到140歲

饑餓可能減慢細胞分裂率，或者激活一些基因，這些基因能保護重要器官，抵製緊張綜合症，這是人基本生存技能的再現。  

少吃多少呢？少吃最少30%。如果一天基本攝熱量2000卡，那就要減少到1400卡以下，就是一個YAMMY,YAMMY抹了美奈子和夾著烤鹹肉的大牛肉漢堡的熱量。 

不想節食，但還想長壽？；-） 喝紅酒吧！ 

紅酒有一種物質resveratrol，有類似饑餓作用的長壽功能，但你要像喝水一樣，大量喝紅酒，身體才能吸收足夠的resveratrol。 

好的東西，都是難得的，好男人好女人，金子鑽石，多彩的思想和智慧，之所以寶貴是因為太少了。節食是件上上難事，喝那麽多紅酒，酒精也會殺人嘛。所以長壽可貴。 

結論：能少吃就少吃些，活久些，變個老妖精，成為兒孫們的負擔；-） 

如果做不到也不打緊，吃，乃人生一大樂趣也！那句話怎麽說？痛快淋漓的一生，做想做的，說想說的，生命也精彩。

Food for Holiday Thought: Eat Less, Live to 140?

By DAVID HOCHMAN

IN his quest to reach the age of 143, Michael A. Sherman is making his peace with doughnuts. Renouncing potato skins and chocolate-chip pancakes was no problem, but he just hasn't found a substitute for a glazed, oven-warm bear claw oozing with apple filling. ''I love them, but the larger specimens of that species can approach 1,000 calories,'' he said a few weeks before Thanksgiving, a holiday he can't get overly excited about. ''That's almost as much as I allow myself in a whole day.''

To say Mr. Sherman is on a diet is to say NASA's Voyager spacecraft, still twinkling at the far edge of our solar system, is on a Sunday drive. Six years ago, Mr. Sherman put himself on the most brutal calorie-reduction plan imaginable. Not that he was especially overweight at 5-foot-5 and 145 pounds. But by switching from pizza and chips to flaxseed, brewer's yeast and sprouts, he whittled his daily caloric intake to less than 1,600, and dropped his weight precipitously, dumbfounding his friends and family.

''Here was a one-time competitive power-lifter who looked to me like a concentration camp refugee,'' said his wife, Kathy, who almost divorced him because of it. In those first two years, Mr. Sherman's libido disappeared, he was cranky, cold and flatulent all the time, and people suspected he had cancer or AIDS. ''Michael's skin hung off his body like you see on old men,'' she said.

Paradoxically, old age was exactly what Mr. Sherman was shooting for. After reading that drastic calorie restriction slows the aging process in laboratory animals, he vowed to starve himself to stretch out his golden years into the 22nd century. If mice, geese and guppies could extend their life span 40 to 50 percent by eating 40 percent less than they wanted, why couldn't he?

''I'm definitely not one of these guys who says, 'Ooo, 18 more years and I can retire,' '' said Mr. Sherman, 46, who runs a biotech company in California near his Silicon Valley home. Now that he's acclimated to the diet and is somewhat bulked up from weight lifting, he looks more like a cyclist than a ''Survivor'' finalist. ''I feel very much like I did at 20,'' he said. ''Nothing but blue sky ahead of me.'' Mr. Sherman is part of a curious subculture of scientists, philosophers, futurists and assorted high-minded anorectics who believe that saying no to dessert (and sometimes to breakfast, lunch and dinner, too) will be the ticket to superlongevity.

Advocates of the strategy, known as calorie restriction, or C.R., insist they're not dieting to get skinny but rather to have the last laugh. Eat smart enough, they say, and you can live to see great-great-grandchildren, not to mention postpone the onset of cancer, diabetes, heart disease and kidney failure.

''Aging is a horror and it's got to stop right now,'' said Michael Rae, a vitamin researcher from Calgary, Alberta, and a board member of the Calorie Restriction Society, which has about 900 ultralean members worldwide. ''People are popping antioxidants, getting face lifts and injecting Botox, but none of that's working,'' he said. ''At this moment, C.R. is the only tool we have to stay younger longer.'' It's worth mentioning that Mr. Rae is 6 feet tall, weighs just 115 pounds and is often very hungry.

In a society obsessed with dieting, in which fads increasingly have the power to reshape the eating habits of millions -- the Atkins diet, the South Beach diet -- the C.R. lifestyle, with its abstinence ethos, will probably never win mass appeal. But the extremism of the diet does seem to fit the present mood, so much so that last month, the President's Council on Bioethics released a report specifically mentioning calorie restriction, and warning, ''The pursuit of an ageless body may prove finally to be a distraction and a deformation.''

Researchers have known about the Methuselahan powers of eating less since the 1930's, when a Cornell University nutrition professor unexpectedly discovered that dieting rats tend to live 30 percent longer. Similar reactions have since been found with fruit flies, monkeys and Labrador retrievers, but the impact of calorie reduction on humans has been mostly speculative.
