@jamesinsonoma and @rwinney there is also a free app you can download on your phone called Zero which will track the different types of intermittent fasting schedules for you. @LeeAase has a health journey blog that was really helpful getting me started with intermittent fasting...has different links/references in the blog entries.

I found the Dr. Jason Fung video link in this blog entry - Our 10 Weeks of Alternate Daily Fasting: https://social-media-university-global.org/2020/02/our-10-week-alternate-daily-fasting-experience/. You can find all of the blog entries here:
