13. Caloric Restriction Theory: Diet full of nutrients, like minerals and vitamins along with regular exercise, can delay the process of ageing. (Turner, 2003). Proposed by Dr. Roy Walford, he focused on high nutrient low-calorie diet , explaining that under nutrition and malnutrition could impair normal functions. A person in this experiment would lose weight gradually till a point of metabolic efficiency has been reached. It was further emphasized by him to take nutritional supplements and regular exercise (Turner, 2003). Major effect of this theory is induction of neuropeptide Y in the arcuate nucleus., on calorie restriction. And it was suggested that this neuropeptide Y is responsible for process of behavior modulation, anxiety and learning. 14. The Rate of Living Theory: Slower use of energy slows the process of ageing, the faster use of energy hasten its rate of decline. (Bengtson and Schaie, 1998). This theory was first given by German physiologist Dr. Max Rubner in 1908 who demonstrated the relationship among the metabolic rate and body size. Basic premise of this theory is that these processes are rate dependent. And there are limited factors available (Bengtson and Schaie, 1998). Non-stochastic theories: 1) The Genetic Control Theory: Process of aging depends on our inheritance from genes. (Bengtson and Schaie, 1998). Every individual has its own genetic coding which predetermines the process of ageing and the rate of this process. This biological clock own
