When presented this almost fairyland notion of being hungry, the new fountain of youth, the public altogether with the scientist were fascinated and surveys and studies kept on going. People have started to do this on their own with no actual proof yet that this will surely work but at the same time stating that this surely is a new and a well improved healthy life style that works for them.

The ‘Calorie Restriction Society’ has members from all over the world and the president of this society, Brian M.

Delaney, informs us that there are thousands of people trying on this type of dieting of calorie restriction, a regime high in nutrients but low in calories, on themselves. Measurements on effects of life span could take decades thus there is no actual proof that calorie restriction will actually work on people. At the same time being such a long term study it will cost a fortune to keep it up thus scientist working partially on this long term goal.

There are studies that show us that a low –calorie diet will surely reduce the weight and will alter the metabolism in obese people but there is no actual data on non-obese people.

Forty-eight people partaken such a study for a period of six months by reducing 25% of the calories needed per day and some reducing much more, coming to an overall amount of 890 calories per day. The results form this study were shocking as experts would describe them leading to a decrease in insulin levels and body temperatures, declines in DNA damage and a minimizing in hormones of the thyroid. These are all signs of longevity but the experts that were directing this study did not conclude that calorie restriction will surely make people live longer or could make people healthier.

There is a well known theory that cutting down calories and losing weight will lead to a slow metabolic rate this being a defensive mechanism in fighting the loss weight, a trait that was preserved by evolution, saving people from starving to death when food was scarce. Eating less could lead to a slower metabolism and a lower level of free radicals that could damage DNA, which would be the main cause of aging.
