For those of us who are always on a diet, eating fewer calories is a way of life. But we've got nothing on the Calorie Restriction Diet.

According to The Calorie Restriction Society, consuming much fewer calories (1,200-,1,400 for women and 1,800-2,000 for a man) and plotting all your essential nutrients will help you live a longer life.

Followers also sometimes uses fasting to achieve anti-aging. However, weight loss is not the goal, longer life is.

To get a taste of how it works, check out Julian Dibbell entertaining article in The New Yorker. Dibbell tried it for two months and went from 178 pounds to 157.

And check out Rebecca Traister's thoughtful response to Dibbell's piece on Salon.com.

While the weight loss definitely sounds enticing, starving doesn't and nor does the constant tracking of food intake. But my biggest issue is the lack of food fun. Maybe my life will be shorter, but I am gonna enjoy the heck out of it.
