Two very prominent theories of aging are the free radical theory and the glycation theory, both of which can explain how calorie restriction could work. With high amounts of energy available, mitochondria do not operate very efficiently and generate more superoxide. With calorie restriction, energy is conserved and there is less free radical generation. A calorie restricted organism will be less fat and require less energy to support the weight, which also means that there does not need to be as much glucose in the bloodstream. Less blood glucose means less glycation of adjacent proteins and less fat to oxidize in the bloodstream to cause sticky blocks resulting in atherosclerosis. Type II Diabetics are people with insulin insensitivity caused by long-term exposure to high blood glucose. Obesity leads to type 2 diabetes. Type 2 diabetes and uncontrolled type 1 diabetes are much like “accelerated aging”, due to the above effects. There may even be a continuum between calorie restriction and the metabolic syndrome.

In examining Calorie Restriction with Optimal Nutrition, it is observed that with less food, and equal nutritional value, there is a higher ratio of nutrients to calories. This may lead to more ideal essential and beneficial nutrient levels in the body. Many nutrients can exist in excess to their need, without side effects as long as they are in balance and not beyond the body’s ability to store and circulate them. Many nutrients serve protective effects as antioxidants, and will be at higher levels in the body as there will be lower levels of free radicals due to the lower food intake.

Calorie Restriction with Optimal Nutrition has not been tested in comparison to Calorie Excess with Optimal Nutrition. It may be that with extra calories, nutrition must be similarly increased to ratios comparable to that of Calorie Restriction to provide similar antiaging benefits.

Stated levels of calorie needs may be biased towards sedentary individuals. Calorie restriction may be no more than adapting the diet to the body’s needs.

Although aging can be conceptualized as the accumulation of damage, the more recent determination that free radicals participate in intracellular signaling has made the categorical equation of their effects with “damage” more problematic than was commonly appreciated in years past.
