In the 1930′s some of the first research was completed by Clive McCay at Cornell University, from that time period onward there has been a huge increase in the amount of studies giving credibility to the ideal that calorie restriction (CR) will increase the length of one's life and slow metabolic and age related disease onset. Traditionally the method for doing this is to reduce the amount of food consumed while avoiding malnutrition. Reducing caloric intake: 1) Lengthens life, 2) Slows aging 3) Lowers the chances or may altogether remove the risk of the onset of many diseases.
The law of Hormesis states that in small doses an otherwise dangerous substance is actually healthy. Rather than decreasing food in general, one should decrease calories and increase exercise levels. This will provide the body with more than enough nutrition while burning excess storage of weight.
Diet may play a strong part in increasing or decreasing blood sugar (glucose), brought on by carb intake, excess glucose in the blood may cause acceleration of aging. Glucose and tissue protein reactions is known as glycation of proteins. This can lead to a number of structural abnormalities in the cardiovascular system, and a variety of other issues throughout the body. Glucose is interactive with DNA which can result in a change in genetic functionality.
In summary, CR is a hormetic process and acts as a low-level stressor to enhance protective and repair processes in the organism. In the Ellis Model of anti-aging avoidance induced by CR, the process can be further refined and strengthened by creating a relative calorie reduction rather than an absolute one and by reducing total carbohydrate intake to avoid glycation and its associated destructive effects.
