“Leptin is a hormone that is secreted by fat cells in white adipose tissue (figure 1). Leptin was found to be a signal to the brain, having a primary influence on body weight. It was also discovered to be involved with insulin, cardiovascular health, reproductive function, sex hormones, immune function, adrenal function, stress, thyroid function, bone health, cancer, and inflammation. Indeed, it has a major determining role in many aspects of healthy function. When leptin falls out of natural balance and loses its ability to communicate efficiently, health problems follow. Thus, the concept of fat as a storage place has been transformed to fat as a major endocrine organ, like the thyroid gland, adrenal glands, and sex glands.19”
