How does aging typically affect the metabolism of fat?

As individuals age, various physiological changes occur, particularly in the body's metabolism. Among these changes, the metabolism of fat generally slows down, which is often attributed to several factors such as a decrease in physical activity levels, a decline in lean body mass, and hormonal changes that accompany aging. The result is that while caloric intake may remain the same, the body becomes less efficient at utilizing fat for energy, leading to an accumulation of fat stores, especially if energy expenditure decreases.

This shift in fat metabolism can contribute to changes in body composition, with an increase in body fat percentage occurring even if total body weight does not drastically change. Therefore, the slowing of fat metabolism in aging individuals is significant and can influence overall health, nutrition strategies, and weight management considerations in gerontological care.
