Insulin is a food hormone. Every time you eat, you need insulin. Its primary job is to take sugar out of your bloodstream. But the key is how much insulin you need. If you use too much, you can develop insulin resistance.

Dr. Martin looks at three new studies on insulin resistance. Researchers have discovered that apart from food, you can develop insulin resistance. A stressful environment, for example, can cause prolonged cortisol that can lead to insulin resistance.

Join Dr. Martin as he teaches on insulin resistance and shares the other ways insulin resistance can be caused.
