What are the energy requirements for underweight older adults experiencing unintended weight loss or weight maintenance?

For underweight older adults who are experiencing unintended weight loss or need to maintain their weight, their energy requirements generally fall within the range of 23-30 kcal/kg. This range is important because it accounts for the unique metabolic needs of older adults, who may have reduced muscle mass and different metabolic rates compared to younger individuals.

Older adults often face challenges such as decreased appetite, changes in nutrient absorption, and potential underlying health issues that can impact their overall energy needs. Therefore, a higher caloric intake is recommended to help prevent further weight loss, support muscle maintenance, and promote overall health.

Choosing 23-30 kcal/kg is seen as appropriate in this context as it provides a sufficient caloric intake tailored to their individual health status and activity level, allowing for flexibility in energy needs based on various factors impacting their health. This specificity in recommended caloric intake is crucial in the nutritional management of older adults, particularly those who are underweight or facing unintended weight changes.
