That’s the question that Dr. Jockers is answering today as he is interviewed by Dr. John Dempster, a Toronto-based naturopath who assists his patients in achieving optimal health, balance, and wellness in their lives through his work at the Dempster Clinic.  This interview is part of the Gut Reset Summit, which is free to access for a limited time.

Today, Dr. Jockers is sharing the story of how he used intermittent fasting as a young medical student to overcome his irritable bowel syndrome. If you haven’t heard how Dr. Jockers got to where he is today in terms of his own health journey, you’re going to want to listen to this!

The science of intermittent fasting is also unpacked as Dr. Jockers explains how exactly we can build a resilient gut lining. Learn about autophagy, glycogen, and how best to repair our body’s cells in an energy-conserving way. 

This episode gives an amazing overview of the importance of autophagy and intermittent fasting. Plus, there are some great insights for pregnant women and other people who might consider themselves too high-risk to give intermittent fasting a try.

Please join us and share this with someone you love who is perhaps new to the good work of Dr. Jockers and his Functional Nutrition team!
