The older adult experiences several physiological changes that lend to anorexia: (i) loss of homeostasis, (ii) the ageing gut, (iii) declining senses, and (iv) hormonal andneurotransmitter changes. Numerous studies have documented an age‐related decline in appetite and energy intake in healthy, ambulant, non‐institutionalized people.²³ Healthy older adults are less hungry and are more rapidly satiated after eating a standard meal than younger people. Much of this decrease in energy is likely a response to the decline in energy expenditure that also occurs during normal ageing.
