What Does Insulin Do For Your Body?

If you know anything about insulin you probably know that it is the substance that diabetics inject into their bodies in order to help them maintain their health. Odds are that you don't know much more than that, and probably have never given your own insulin levels any thought. But the truth is that few hormones are as important in regulating your health and weight as insulin, and understanding how this hormone functions in your body is critical to controlling and keeping your health in check. In today's article we're going to take a close look at insulin, and talk about the critical basics that you need to know.

Insulin is a peptide hormone, which means it's protein based. It's released by your pancreas, and this happens primarily as a response to how much glucose is in your blood. Thus if you eat a big plate of pasta and those carbs get processed and turned into glucose, your insulin levels will increase as well to help you control that amount of glucose in your blood by storing it as glycogen in your liver and muscle cells. Excess glucose can be stored as fat, and during all this time more protein synthesis can be stimulated along with fat storage. The release of free fatty acids is inhibited by even small spikes of your insulin levels.

All insulin is interested in doing is keeping your glucose levels in a range between 80-120 mg/dl. When your blood glucose rises above this, insulin is released to bring it back down. Nothing will do this more than your good old carbs such as pasta, bread, starchy vegetables and grains.

Conversely, let's say you go out and do a ton of exercise. You burn up all the glucose in your blood, and then even deplete the glycogen in your liver and muscles. With this drop of glucose your insulin levels also drop. When insulin drops, other hormones will increase, and this will signal to your body to begin breaking down other forms of stored energy for use such as protein or fat.

The reason diabetics inject insulin is because their bodies can no longer create it, meaning that without those shots their glucose levels will go through the roof. You always need to keep your insulin levels between that magic 80/100 mark, or you will begin to severely hurt your health and need help fast.
