The primary role of white fat in the body is to store energy in the form of triglycerides. This adipose tissue serves as an essential energy reserve that can be drawn upon during periods of calorie deficiency. Additionally, white fat acts as an insulator, helping to maintain body temperature and protect organs by providing a cushioning layer. It also plays a significant role in hormonal regulation, secreting hormones such as leptin, which influences appetite and energy balance. Thus, white fat is crucial for overall metabolic health.
