The Effects of Intermittent Fasting on Type 2 Diabetes

  • Anna Mackenthun


Type 2 diabetes occurs when a body does not use insulin properly: either the body begins to

resist insulin or the pancreas does not produce enough insulin. The exact cause of type 2 diabetes is

unknown, but genetic and environmental factors appear to be key contributors to its development.

Because the prevalence of this condition is increasing, it is important to find new ways to manage it.

One such way is intermittent fasting. Intermittent fasting is a cycle that requires a specific eating time

followed by a voluntary fasting time. This repeating cycle is known to provide many benefits including

weight loss, increased energy, mental focus, cardiovascular health, and reversal of diabetes. There have

been few studies on the effects of intermittent fasting on type 2 diabetes. Many of these studies were

completed on rodents, while a few focused on human subjects suffering from type 2 diabetes. All studies

described in this review have found benefits of intermittent fasting relating to type 2 diabetes, but the

mechanisms the researchers found vary. The aim of this review is to present the research established

on intermittent fasting and type 2 diabetes while acknowledging the differences in results and the need

for further study. The sections of this review will explore the effects of intermittent fasting on insulin,

the mechanisms that improve insulin sensitivity, as well as the feasibility of intermittent fasting as a

treatment strategy for type 2 diabetes.
