A recent research has been able to unravel a molecular pathway that has been able to demonstrate how eating less can result in providing an anti-ageing effect. The anti-ageing effect is such that a person's life can be extended by consuming lower amounts of food.

While talking about the discovery, Tomas A. Prolla, University of Wisconsin stated that they were slowly discovering the functioning calorie control. He added that the working of calorie control was the best way to present, how life can be elongated by eating less.

John M. Denu from the Wisconsin Institute of Discovery, University of Wisconsin stated that the group of researchers was able to discover an enzyme known as Sirt3, which was found to be helpful in improving longevity of mammals. The enzyme was enzyme was found in abundance, when mammals ate less.

Sirt3 is known to be responsible for changing the metabolism of people, which result in the release of fewer radicals by mitochondria cells. The radicals are known to compose of highly unstable forms of oxygen, which can cause damage to cells and also increase the rate of ageing in mammals.

The conclusion was supported by a research on a mouse, who was suffering memory loss because of ageing. It was found that on eating more the hearing got worse, however, a reduced diet helped in improving the hearing abilities of the mouse.
