What is one essential role of body fat in humans?

Body fat plays a crucial role in human physiology, particularly in providing energy and insulating organs. Adipose tissue, which is the body's fat, serves as a significant energy reserve. When the body requires additional energy, especially during periods of fasting or intense physical activity, it can mobilize stored fat to meet metabolic needs.

Moreover, body fat acts as a protective cushion for vital organs, helping to prevent injury from external shocks. This insulation helps maintain a stable internal temperature by reducing heat loss from the body. Thus, body fat is not only a source of energy but also a critical component in protecting and maintaining the proper function of organs, contributing significantly to overall health and physical well-being.
