That has not been demonstrated in humans. Restricted
calories does extend the life of mice. Nevertheless,
as noted in
'"With mice, if you restrict their caloric intake by
10 percent, they live longer than if they have
unlimited access to food," Phelan said. "If you
restrict their intake by 20 percent, they live even
longer, and restrict them to 50 percent, they live
longer still; but restrict their intake by 60 percent
and they starve to death."'
Certainly, obese humans have many more health
problems, but restricting your calorie intake about
2000 calories appears to improve health but not how
long you will live.
If you are looking for a magic pill or program that
will allow you to live to be 100, I would first look
at how long your parents lived and what is your

We must face the fact that the United States is neither omnipotent or omniscient that we are only 6 percent of the worlds population; that we cannot impose our will upon the other 94 percent of mankind; that we cannot right every wrong or reverse each adversity; and therefore there cannot be an American solution to every world problem.
