Compared to healthy young adults, older people on average are less hungry, consume smaller meals more slowly, and have fewer snacks between meals; as a result, their energy intake is about 20-30% lower than younger people. In particular, control of energy intake is less responsive (to stimulation or inhibition) in older than younger subjects. The gastrointestinal tract has important actions in regulating appetite and food intake, which are modified by healthy aging. These include the effects of gut hormones and the rate of gastrointestinal motility. The duration of long-lasting satiety and hunger suppression after a meal are proportional to these gut hormone concentrations.
