According to experts, calorie restriction (CR) reduces the concentration of TNF (Tumor Necrosis Factor alpha), a circulating inflammatory molecule in the body. Reducing the TNF combined with lower T3 levels slows down the process of aging as the metabolic rate of the body as well as the damage caused to the cellular system due to oxidation is considerably reduced. (See Reference 1)

Experiments conducted on mice revealed that when endurance exercise is combined with calorie restriction, it protects them from many types of chronic diseases including diabetes, cardiovascular diseases, obesity as well as certain types of cancer.

Further to this, a research was conducted on a sample of Calorie Restriction Society members who had been strictly following CR diet for more than 5 years. The second sample consisted of people who ate standard western diet. Another group of people who participated in this study ate standard western diet but also included endurance training as a part of the routine. (See Reference 1)

Reports revealed that CR diets can increase the lifespan of an individual as maintaining healthy body shields it from many diseases associated with aging. In addition, the concentration of T3 levels was lower in the first and third research group. It has to be noted however that the sample group did not compromise on the recommended nutrient amounts though they consumed fewer calories. (See Reference 1)

Calorie restriction helps to slow down the primary aging process considerably. Since primary aging determines the life span of an individual, it can be concluded that CR can also increase the longevity of life.
