About this episode
Episode #227 In this Fasting Q&A episode, hosted by Coach Lisa Chance, Dr. Jason Fung answers questions from the TFM Community: 1. Can people tweak the 5:2 diet with the two non-consecutive restricted calorie days as full fast days (water only) and reap the same if not better results, or must food in the form of nutrient dense and low calorie be consumed? [09:21] 2. I have seen videos of Dr Fung endorsing the Fasting Mimicking Diet (FMD). Does he, Dr Fung advocate it for T2D? I am asking because of the plant based (carb) items in the kit, like the soups, crackers, and bars and the potential spike in insulin and glucose consuming those items? [14:30] 3. While an individualized approach to managing and/or reversing diabetes is best, from a diet perspective, is it generally better to have a diverse diet and manage diabetes with medication if needed, rather than restricting your diet to avoid medication? [18:55] 4. Can one - or more importantly should one - practice OMAD to reverse IR or T2D? Is there a nutritional concern here? Is the length of time that you do OMAD a factor? [21:12] 5. Do I have to leave the weights workout for the last day of prolonged fasting and eat after the workout or can I work out with weights every day during a 5-day fast without problem and continue fasting AFTER the heavy weights workout? [27:01] 6. Is long term ketosis bad for the body? Some doctors are saying it is and you should carb cycle, but are there any studies supporting this?
