Fasting to 100: When to Eat—and When Not to—for a Longer, Healthier Life
I gave this talk, virtually, at my friend Dan Buettner’s Blue Zones American Kitchens Conference in November 2022. It’s about the latest research into when to eat each day to avoid disease and live longer. Watch below or on YouTube. Posted December 2022.
Can Fasting Reverse Long Covid?
The world’s leading fasting clinics have reported that a number of their patients have reversed their long COVID while fasting. I explore some of these cases and the repairs induced by fasting that might be behind their reversals. Watch below or on YouTube. Posted March 2023.
For links to more information on some of the cases I discuss: the retired German headmaster, the doctor from Geneva, the dentist from London (also here), and the wine dealer from Strasbourg. You can also watch the doctors of Germany’s Buchinger Wilhelmi Clinic discuss fasting’s potential to reverse long COVID.
The Science of Fasting for Rheumatoid Arthritis
Peer-reviewed research shows fasting can reverse the debilitating autoimmune disease of rheumatoid arthritis. Watch below or on YouTube. Posted July 2022.
The Science of Fasting for Cancer
I was going to make a video on fasting for cancer, but the ever-useful Dr. Michael Greger of NutritionFacts.org has done an excellent series of short videos (Part 1, Part 2, Part 3) showing how fasting can make chemotherapy and radiation less awful for patients while also potentially killing more of their cancer. Note the tabs under each of Greger’s videos showing the transcript and a list of scholarly citations, which may be useful in convincing doctors who are unfamiliar with fasting that short fasts are both very safe and very helpful for patients undergoing cancer treatment.
One caveat about Greger’s series: In Part 3, I think he goes far too easy on the 2017 study in Clinical Nutrition that claimed fasting wasn’t safe during chemotherapy. The authors of the study expressed three concerns, all perhaps understandable but quite wrongheaded nonetheless: First, they feared fasting patients could become malnourished, but they never explained how a short fast could cause malnutrition. In short, it doesn’t. I’m aware of no study that has ever shown a fasted chemo patient to have become malnourished from their fast. Second, the authors feared that “patients might be tempted to prolong” their fasts, but they cited no evidence that patients were likely to do so, perhaps because, again, no such evidence has been reported in any study to date. Third, the authors said there was no “firm evidence of a benefit” from fasting during chemo, yet we have multiple studies showing that fasting reduces the awful side effects of chemotherapy, which is a pretty amazing benefit. It’s also astonishing to me that the authors never mentioned that multiple human trials have found fasting and fasting-mimicking diets (FMDs) entirely safe for patients undergoing conventional cancer treatments like chemo and radiation. If I’m being charitable, I might say that omission was understandable in 2017, when there were fewer such safety studies. But it certainly wouldn’t be an acceptable conclusion today, and it probably wasn’t even back then. In short, it seems the authors were writing from the old benighted view that not eating just has to be harmful, particularly for sick people. As my book amply documents, for a great many sicknesses, nothing could be further from the truth.
