Fasting Q&A with Dr Jason Fung: Smoothie...

The Fasting Method
About this episode

Episode #193

In this Fasting Q&A episode, hosted by Coach Lisa Chance, Dr. Jason Fung answers questions from the TFM Community:

  1. Are home-made smoothies and protein drinks helpful or detrimental as meal replacement when trying to lose weight or reverse type two diabetes? If so, what kind would you recommend? (05:14)
  2. Is it acceptable for someone 4’10” to eat 0.6 grams of protein per kilogram instead of TFM’s recommended 0.8-1.2 gram, since they are so petite? (08:32)
  3. How does iodine intake and storage work in the body from a scientific perspective? Since iodine is water soluble, what is known about how long the body can maintain adequate iodine levels between dietary intake? Are there any established research findings about the need for iodine during different eating patterns, such as an extended fast? (12:02) 
  4. Will consistently high uric acid levels from fasting adversely affect my health even if I don't have symptoms of hyperuricemia? (14:08) 
  5. I believe you addressed this at the time Dr. Peter Attia was a guest on Thomas DeLauer’s YouTube channel, but I can’t remember which one of our podcasts that was. Wasn’t he cautioning about extended fasts and muscle loss for people who were already in great shape - “shredded” if you will? Don’t you quickly regain any muscle lost once you start eating nutrient-dense food again? (15:21)
  6. Is there more autophagy happening during exercise or fasting? (21:17)
  7. What is the best fasting regime for someone with a low BMI but who has non-alcoholic fatty liver disease? How long should alternate-day fasting (just started two 42-48 hour fasts a week) combined with a whole-food, low-carb diet continue? (23:46)
  8. What are your thoughts on fasting while taking ADHD medication? (25:04)
  9. Do you have any recommendations for a diet that will starve or kill cancer? (26:23)
  10. How long does it take to reverse insulin resistance while doing fasting and low-carb and how do you know when you have? (27:42)
