The body has a natural way of regulating weight from "summary" of The Obesity Code by Dr. Jason Fung
Obesity is not simply a matter of willpower or lack thereof. It is a complex, multifactorial condition that is influenced by a variety of factors, both genetic and environmental. One key factor in the development and regulation of obesity is the body's natural ability to maintain a stable weight. This natural regulation is governed by a set of intricate hormonal mechanisms that work together to ensure that the body stays within a certain weight range. One of the primary hormones involved in the regulation of weight is insulin. Insulin is a hormone that is secreted by the pancreas in response to the consumption of carbohydrates. Its primary role is to regulate blood sugar levels by promoting the uptake of glucose into cells for energy production. However, insulin also plays a crucial role in the storage of excess energy in the form of fat. When insulin levels are elevated, the body is in storage mode, and fat accumulation is promoted. Conversely, when insulin levels are low, the body is in a state of mobilization, and fat stores are broken down for energy. This delicate balance between storage and mobilization is essential for maintaining a stable weight. When this balance is disrupted, as is often the case in obesity, weight gain can occur. In addition to insulin, other hormones such as leptin and ghrelin also play important roles in the regulation of weight. Leptin is a hormone produced by fat cells that signals to the brain when energy stores are sufficient, leading to a reduction in appetite and an increase in energy expenditure. Ghrelin, on the other hand, is a hormone produced by the stomach that stimulates hunger and promotes food intake.- The body is able to maintain a stable weight within a certain range. However, in obesity, these hormonal signals can become dysregulated, leading to increased appetite, decreased energy expenditure, and ultimately, weight gain. By understanding the intricate interplay of these hormonal mechanisms, we can begin to unravel the complexity of obesity and develop more effective strategies for prevention and treatment.
