Insulin plays a crucial role in the body primarily by helping to convert food into energy. This process is vital for maintaining normal blood sugar levels. When you consume carbohydrates, they are broken down into glucose, which is the primary energy source for your cells. Insulin, a hormone produced by the pancreas, facilitates the uptake of glucose into the cells, allowing them to utilize it for energy. This not only helps in providing energy but also in storing excess glucose as glycogen in the liver and muscles for future use.

While other options touch on important bodily functions, they do not accurately describe the primary function of insulin. For instance, stabilizing blood pressure is more closely related to other hormones and body systems, such as those regulating vascular tone and fluid balance. Similarly, while the body’s temperature regulation involves various mechanisms, it is not directly affected by insulin. Muscle recovery is influenced by several factors, including nutrients and rest, but insulin's primary function is not centered around this recovery process.
