a hormone responsible for the accumulation of fat in the body

Insulin is a hormone that plays a key role in the regulation of glucose and fat metabolism in the body. It is produced by the pancreas and is responsible for helping cells take up glucose for energy or storing it as fat when energy intake exceeds energy expenditure. High levels of insulin can lead to increased fat storage and make it more difficult for the body to break down stored fat. Additionally, cortisol, often referred to as the "stress hormone," can also contribute to fat accumulation, particularly in the abdominal area, when it is elevated over extended periods. Both hormones are important in understanding how the body manages fat storage and energy balance.
