Life expectancy - Extend your life by eating less, way less
[Edit]
[Edit]
So you wanna get a 100 years old? Scientists are getting closer to find out what causes aging - how to delay it, and how to transfer their findings from the lab to real life. Forget about taking pills, stem cell replacement therapy, injections of human growth hormone and testosterone. High on the promising list of longevity candidates is Calorie Reduction, in other words, eating less calories - like 30% up to 70% less than recommended.
Drugs or supplements that mimic the effects of CR without requiring starvation would be a boon, researchers say. But there’s one big problem: “There are a lot of theories, but the actual mechanism by which CR works is not known,” Hadley says.
So far, the most promising candidates appear to be those that affect a series of proteins known as sirtuins, which may influence the processes that govern cell metabolism and death. In humans, one of the most important seems to be SIRT1, a gene that appears to help regulate the metabolic pathways linked to aging, particularly those linked to diabetes and obesity.
