Fasting Q&A with Dr Jason Fung: Off-Label Use of GLP-1s, Double Diabetes, Seed Oils, and More.

Episode #206

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

1. Are there common strategies that help to avoid the common pitfalls of Ramadan, like late night eating, overeating, or accidentally doing OMAD for too long and slowing down the metabolic rate? [01:07]
2. Concerns about off-label use of GLP-1s. Some medical professionals seem to be prescribing GLP-1 medications for anti-aging/longevity purposes in people who aren't overweight or diabetic. What do you think about the trend of “microdosing” GLP-1s as a preventative health measure? [02:36]
3. Are there further short and long-term side effects of GLP-1s coming to light? [06:36]
4. Are there ethical concerns around supply issues with GLP-1s due to increased demand from off-label use? [ 10:12]
5. Are there bioethical concerns about GLP-1s that doctors should be discussing with patients? [12:03]
6. Can you address how people with Type 1 diabetes can develop insulin resistance similar to those with Type 2, sometimes referred to as ‘double diabetes’? [16:21]
7. How concerning is an elevated Lp(a) and how can you lower it? [20:47]
8. Do you know of research or trials with fasting to reduce prostate size?  [26:28]
9. Can someone who is considering kidney donation fast/fat fast? [29:08]
10. I'm seeing many reputable sources saying that the claims against seed oils aren't actually based in the science. I'm curious whether Dr. Fung's opinion has evolved on this? [30:51]
