Why body fat acts like an organ and resists long-term weight loss
Body fat, beyond merely storing energy, acts as the body's largest endocrine organ, influencing everything from hunger to immune function. Yet, its stubborn nature means weight loss may not always last due to lasting changes in fat cells themselves. Fat tissue comes in three main types: white, brown, and beige, each serving different purposes. White fat stores energy, while brown fat burns calories to generate heat. Beige fat, a mix of the two, can adapt based on the body's needs. Fat tissue's memory and hormonal influence make weight loss difficult to maintain. Its role in metabolism, immunity, and reproduction highlights how vital it is to overall health. Understanding these functions could lead to better ways of managing weight and preventing disease.
