Insulin resistance is a condition in which the body's cells become resistant to the effects of insulin, which is a hormone that regulates blood sugar levels. When this happens, the body reacts by producing more insulin to keep blood sugar levels under control.
Insulin plays an important role in regulating the body's metabolism. One of its main functions is to help to transport glucose (sugar) from the bloodstream into cells, where it can be used for energy. It is also an anabolic hormone- wherein it contributes to building up of tissues and promoting storage of fat. In the body. So the more insulin the body produces, the more fat it can store. Secondly, high levels of insulin can also stimulate appetite and cause cravings for high-carbohydrate foods, which can further contribute to weight gain.
In summary, insulin resistance can contribute to weight gain by promoting fat storage and increasing appetite for high-carbohydrate foods. It's important to manage insulin resistance through lifestyle changes such as exercise, healthy eating, and maintaining a healthy weight to prevent weight gain and other health problems associated with insulin resistance.
