Fasting Q&A with Dr Jason Fung: Fasting With Low BMI, Oxalates, Metabolic Flexibility, Cancer Treatment and Fasting, Magnesium Supplementation, and More.

Episode #158 In this Fasting Q&A episode, hosted by Coach Lisa Chance, Dr. Jason Fung answers questions from the TFM Community: Does fasting help with not choking for an impacted oesophagus? [01:58] I have been struggling with my fasting due to terrible headaches that last days after 36-hour fasts. I've been put on a bunch of supplements to support me with detoxification including liver supplements, B vitamins, and activated charcoal, but I find that these can sometimes make the headaches worse. I've been advised to do shorter fasts but this doesn't result in any weight loss. Any idea how I can move past this? [03:36] How many meals between fasts is ideal for weight loss? Two or three meals a day? [07:21] I understand how excess carbohydrates can be stored as fat (via insulin)., but I'm having a hard time understanding how dietary fat is utilised and stored if we go low carb and increase our fat intake. Isn't dietary fat stored as fat? I am confused about how we are able to burn body fat while eating more dietary fat. [09:25] Which fasting protocols would you recommend for people who have a low BMI but still have insulin resistance? [13:09] Does miso soup break a fast? It would be a great source of salt and I prefer savory drinks to sour. [15:33] I got a CGM so that I could see my glucose response to various foods. Is it correct to assume/conclude that, if I see an increase or spike in glucose, there will be a corresponding increase in insulin? And, conversely, if I do not see an increase in glucose, there is little or no increase in insulin? Could there be a situation where glucose does not go up but insulin does? Is there a correlation between an increase in ketones and a decrease in insulin? [16:41] I've measured consistently high in oxalate on an OAT test over the last decade. I've read that oxalates are difficult to measure in the body, outside of stones which I'm hoping to preempt. Will fasting, detoxing, releasing toxins help reduce high oxalates? [18:03] Fasts longer than 48 hours have triggered inflammation in individual finger joints. Is that a potentially common way for detoxing or autophagy to present (meaning, the specific, targeted area rather than more broad based)? [19:59] Could you please address the subject of metabolic flexibility? Is it possible to be too fat adapted? [21:22] Since cancer is a disease of too much growth and fasting slows down growth, why is it not a good addition to *most* chemo therapies when the patient has sufficient fat mass to allow for fasting? [24:45] In their book, Brain Energy, Dr. Chris Palmer talks about how ketones are beneficial for brain function. In your Toronto clinic, back in the day, did the patients who fasted under your and Megan Ramos's supervision anecdotally report mental health improvements as they progressed through therapeutic fasting regimens? [30:42] Why do different people need potentially drastically different amounts of magnesium supplementation when they eat the same foods? My partner and I are almost identical age and weight, and have the same activity level and diet. They do not benefit at all from magnesium supplementation, while I need almost four times the recommended daily dose to feel good and not have muscle cramps.
