What generally happens to daily caloric intake as people age?

As people age, there is a general trend toward a decrease in daily caloric intake. This reduction can be attributed to various factors including a decrease in basal metabolic rate (BMR), changes in body composition, and often a reduction in physical activity levels.

As people age, muscle mass typically declines, leading to a lower metabolic rate because muscle tissue burns more calories than fat tissue. Additionally, older adults may become less active due to health issues or lifestyle changes, which further lowers caloric needs. Furthermore, appetite may change due to physiological shifts, medication side effects, or dental issues that make eating more challenging.

Understanding this trend is crucial for nutrition and health professionals, as they can guide older adults to adjust their diets accordingly, ensuring they are still getting adequate nutrition without excessive calories. This knowledge underlines the importance of balanced nutrition that meets the needs of an aging population while preventing weight gain and maintaining overall health.
