Role of Insulin in Fat Cells

Insulin plays a crucial role in fat cells. It stimulates lipogenesis, the creation and storage of lipids, and adipogenesis, the creation of new fat cells. It tells fat cells what to do with energy and promotes the storage of fat. However, when fat cells become hypertrophic, they become insulin resistant and start leaking fat and pro-inflammatory hormones. This leads to the accumulation of ceramides and the spread of insulin resistance throughout the body.
