What is the estimated energy requirement (EER) for older, healthy women?

The estimated energy requirement (EER) for older, healthy women is generally recognized to be around 18-22 kcal/kg. This range is based on factors such as age, activity level, and overall health status. As individuals age, their metabolic rate tends to decrease due to a loss of lean body mass and reduced physical activity, which results in lower energy requirements compared to younger adults.

Using this EER range allows for adjusting caloric intake to support maintenance of a healthy weight while meeting the nutritional needs of older adults. Ensuring adequate nutrient intake while recognizing reduced energy needs is important for maintaining health and preventing excess weight gain.

The other ranges provided (20-24, 22-26, and 24-28 kcal/kg) are higher and are not typically aligned with the accepted guidelines for older, healthy women. These higher estimates may be more suited to younger, more active individuals or populations that have different composition and energy needs.
