The Fasting Method Podcast

Episode #223 In this Fasting Q&A episode, hosted by Coach Lisa Chance, Dr. Jason Fung answers questions from the TFM Community:   1. I am a healthy 46-year-old working to improve my sleep, so I want to take magnesium bisglycinate. My magnesium supplement actually contains 7 forms of magnesium, which is very convenient, but is it better to just take one form in one capsule for absorption or any other reason? [01:23] 2. Two-part question on TFM’s Fat Fasting  One: Vinegar is not on the list, but you have mentioned that we can eat salads. Would it be okay to make a dressing with a healthy oil and vinegar during a Fat Fast?    Two: I've seen some mention to only eat 3-4 of the allowed foods on a fat fast. Is this an alternative manner to step up one's game during a fat fast? [03:58] 3. I just read about a study on stem cell research.  Could you elaborate further what this may mean for those with pancreas, liver, or kidney issues? [08:11] 4. Are there any research-based studies that fasting helps lower cholesterol? [09:55] 5. I’m on day four of a water fast and I am noticing a metallic taste in my mouth. Is this unusual? Why does it happen? [13:46] 6. I have various autoimmune conditions and it was suggested I consider going on LDN (low dose naltrexone), and that this can also help with weight loss. I’m wondering what your thoughts are on LDN for weight loss and, if I decided to start it, how I would incorporate it into my fasting schedule. [16:09] 7. What is the difference between The Dawn Phenomenon and Feet-to-Floor Syndrome? From what I can find they both cause a rise in morning blood sugar, one due to circadian rhythm and the other due to a stress response from getting the day started. Is there a different eating/fasting protocol that is best for one over the other, and how do you know which one you are experiencing? [18:14] 8. Is kidney disease the cause of interstitial cystitis and how do you treat it? [21:05] 9. I have high uric acid and also the APOE 4-4 gene. Would the 3T of lime juice recommended for high uric acid affect the neural autophagy I use as a prevention for the dementia risk? What is the best way to navigate fasting with these two needs? [21:59] 10. Are there any dangers to keeping blood sugars in a consistently low range (50-60’s mg/dl) if no symptoms of hypoglycemia are felt? [24:55] 11. In some fasting groups on-line, they are big into breaking fasts with watermelon and fruit juices. How do you feel about breaking fasts with these things?

Episode #219 In this Fasting Q&A episode, hosted by Coach Lisa Chance, Dr. Jason Fung answers questions from the TFM Community: I realize the relationship between bitters, incretins, and autophagy is more complex than a direct cause-and-effect relationship. The incretin response doesn’t directly “promote” autophagy - it primarily regulates blood sugar and satiety. Autophagy is mainly triggered by nutrient scarcity and low insulin levels, not by bitter compounds themselves.  Can you weigh-in on using bitter greens during this reset? [16:07]  I have had some success lowering weight a couple times using fasting and time restricted eating but the weight creeps back up after a while even with doing TRE. What's nice is that I can get it to go back down again with discipline. I'm wondering what scientific evidence exists that your body set weight can successfully be reset for the long term as mine holds for a while but then wants to creep up and if there's a foolproof method to resetting your body set weight? [19:26] Your kidney patients who are T2D and close to needing dialysis, but are skinny, I’m assuming they need to fast for about a year to reverse the kidney damage, but how do they do it with so little fat mass? [26:56]  I know that vitamin D is fat soluble and best taken with a meal. I’ve also heard that all supplements are better absorbed when taken with a meal. Is this true? What timeframe is considered “with a meal”? Is it before, during or after the meal? Is vitamin D a stimulant and can disrupt sleep so best taken in the morning? [30:32] How do you rate the risk of new gallstones formation if a patient already has one or more when it comes to fasting protocols?

Episode #218 In this week’s Turbo Talk episode, Terri gets real about a truth we often overlook—every goal has a price tag. Whether it’s time, money, energy, risk, comfort, or emotional resilience, every transformation requires an investment.  Terri challenges you to ask yourself three powerful questions: 💡 What do you truly want? 💰 What is it worth to you? 🔥 What are you willing to invest to make it happen? This is your invitation to step into honest self-inquiry—and to stop waiting for change to happen without currency on the table. If you’re ready for results, this episode will help you clarify the cost of your commitment—and whether you're truly ready to pay it.   🚀 Take the first step!
