可以活到140岁

饥饿可能减慢细胞分裂率，或者激活一些基因，这些基因能保护重要器官，抵制紧张综合症，这是人基本生存技能的再现。  

少吃多少呢？少吃最少30%。如果一天基本摄热量2000卡，那就要减少到1400卡以下，就是一个YAMMY,YAMMY抹了美奈子和夹着烤咸肉的大牛肉汉堡的热量。 

不想节食，但还想长寿？；-） 喝红酒吧！ 

红酒有一种物质resveratrol，有类似饥饿作用的长寿功能，但你要像喝水一样，大量喝红酒，身体才能吸收足够的resveratrol。 

好的东西，都是难得的，好男人好女人，金子钻石，多彩的思想和智慧，之所以宝贵是因为太少了。节食是件上上难事，喝那么多红酒，酒精也会杀人嘛。所以长寿可贵。 

结论：能少吃就少吃些，活久些，变个老妖精，成为儿孙们的负担；-） 

如果做不到也不打紧，吃，乃人生一大乐趣也！那句话怎么说？痛快淋漓的一生，做想做的，说想说的，生命也精彩。

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

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.
