How does insulin resistance develop? Dr. Jason Fung explains that in biologic systems, persistent exposure causes resistance due to the near universal phenomenon of homeostasis. Insulin resistance is caused by hyperinsulinemia, which results in more hyperinsulinemia in a vicious cycle. Thinking about hyperinsulinemia helps you understand how diets that reduce insulin may be useful to reverse type 2 diabetes.
