Subcutaneous fat is the fat layer that lies just below the skin. It is the most visible fat, often observed as body fat in areas like the abdomen, thighs, and arms. This fat plays an important role in energy storage, as it holds excess calories that the body can use during times of fasting or high-energy demand.

In addition to its role in energy storage, subcutaneous fat serves as insulation for the body. It helps regulate body temperature by trapping heat and preventing it from escaping, especially in cold environments.

Subcutaneous fat also provides cushioning for the muscles and bones, absorbing impacts and reducing the risk of injury. It acts as a protective barrier against physical trauma by dispersing the energy from shocks and blows.

Although subcutaneous fat is essential for the body’s function, excessive amounts of it can lead to obesity and related health problems, such as high blood pressure, type 2 diabetes, and metabolic syndrome. Maintaining a healthy amount of subcutaneous fat is important for overall well-being.
