Health experts have long warned of the risk of obesity, but a new Japanese study warns that being very skinny is even more dangerous, and that slightly chubby people live longer.
People who are a little overweight at age 40 live six to seven years longer than very thin people, whose average life expectancy was shorter by some five years than that of obese people, the study found.
"We found skinny people run the highest risk," said Shinichi Kuriyama, an associate professor at Tohoku University's Graduate School of Medicine who worked on the long-term study of middle-aged and elderly people.

Amazing how Science repeatedly reveal throughout the years how various groups live konger than others. For instance, how chubby people live longer than skinny people, but not only that, but also that skinny people live longer than chubby people aswell!
You can always count on Science.

I don't believe that one bit, what about the increased risk of diabetes

Just wait a few years and they'll change their mind. They flip flop a lot.
example - eggs are good for you. No, they are bad for you. Wait, wait .. they are now good for you. Hold up ... the whites are good and the yellows are bad ....
I figured more people would be happy reading this thread. Guess not.

Very restricted calorie diets have not shown to increase human lifespan, plain and simple. Scientists are currently studying adult primates to see if CRON increases their lifespan. There are problems, however, with these types of diets.
Firstly, we don't really know why eating less food causes increased lifespan in small animals(insects). Some suggest it is low levels of IGF-1 and Insulin, which indeed to increase the rate of aging when present in high levels. One of the biggest problems I see with very restricted calorie diets on humans is Catabolism, or breaking down of muscle tissue for energy. And the heart, btw, is a muscle.
The telomerase shortening mechanism normally limits cells to a fixed number of divisions, and animal studies suggest that this is responsible for aging on the cellular level and sets a limit on lifespans.
They think that prolonged calorie restriction can trigger genes that slow aging. Or that limiting the calories improves the functioning of mitochondria, so that not as many free radicals are produced. Another thought to explain why CRON increases lifespan is since it slows the rate at which cells divide.
