ABSTRACT

This chapter examines energy requirements of the elderly population, investigates some special problems in energetics and metabolism involving the aging process, and formulates a rational approach to meet the energy requirements in our senior citizens. The energy needs of an individual vary according to the person's metabolic rate, size, sex, activity, physical environment, hormonal balance, and age. Energy homeostasis requires a dynamic balance between nutrient intake and energy expenditure. Beyond changes in the elderly which influence energy intake, there are significant agerelated changes in body composition which may alter nutrient metabolism. Psychological and environmental factors also play an important role in controlling energy intake and utilization. Associated with a decreased metabolic rate with increasing age is the appearance of hyperglycemia in the elderly population.
