Consider this episode a cross between an ask me anything (AMA) and a show-and-tell. Peter discusses his fasting experiment in great detail and answers questions from listeners and readers. We discuss: • Why Peter did a one-week fast and the rationale for front- and back-ending it with a week-long ketogenic diet [6:30]; • What Peter’s typical diet, exercise, sleep, stress management, and supplementation looks like [11:00]; • What labs (e.g., glucose, ketones, lipids, inflammation and oxidation markers, thyroid- and sex hormones) Peter checked for the experiment [22:00]; • Peter’s results after a week on a ketogenic diet [29:30]; • Peter’s results after a week on a water-only fast [48:45]; • Peter’s results after a week on a ketogenic diet following a week of fasting [58:30]; • Peter’s “Top 6” surprises from the fasting experiment [1:08:30]; • Different fasting-mimicking diet (FMD) protocols [1:29:20]; • What is the optimal protocol, frequency, and duration for fasting? [1:33:00]; • How to break a fast without GI distress? [1:38:00]; • “Am I breaking the fast if…?” [1:41:30]; and • More.
