About this episode
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?
