Ageing is associated with a decline in energy (food) intake. Energy intake decreases by ~30% between ages 20 and 80.²³ Elderly people on average consume smaller meals more slowly and fewer snacks between meals,¹ and consistently report that they are less hungry than young adults.²⁴ For example, the 1989 cross‐sectional American National Health and Nutrition Examination Survey (NHANES III) study reported a decline in energy intake between the ages of 20 and 80 of 1321 cal per day in men and 629 cal per day in women.²⁵ A seven‐year New Mexico longitudinal study of 156 people age 64–91 reported a decrease of 19.3 kcal per day per year in women and 25.1 kcal per day per year in men,²⁶ and a Swedish six‐year longitudinal study of 98 people found that between the ages of 70 and 76 there was a decrease in energy intake of 610 cal per day in men and 440 cal per day in women.²⁷
