Summary
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? [32:27]

| 0:00.0 | remember fasting is a stress that's not necessarily a bad thing exercise is a stress on the body too |
| 0:05.4 | but you have to sort of balance it you don't want to stress yourself all the time so when you're |
| 0:10.2 | going longer and that's like five days then perhaps a little bit of calories may be okay always stick |
| 0:17.3 | to natural foods low in carbohydrates, especially refined carbohydrates. |
| 0:21.8 | But when you're going only a day, then it's no problem. |
| 0:24.7 | So the last fasting reset, what I typically do is I don't eat anything for the first two days. |
| 0:32.2 | And then the last few, then I'll have a little bit. |
| 0:36.5 | Usually I take like three to 400 calories. Day three, day four, |
| 0:39.9 | I typically take a little bit of vegetables. And remember, I'm taking a little bit of bone bra. So I'm |
| 0:44.3 | probably getting like 50 calories of that. |
| 0:52.6 | Hello to our podcast listeners. |
| 0:55.1 | This is our monthly Q&A with our very own Dr. Jason Fung, where he tackles questions submitted by our TFM community members. |
| 1:03.6 | And I have an exciting announcement for next month. |
| 1:07.4 | Patrice Mitchell, who is one of our fasting methods community mentors, will be joining us for our |
| 1:14.3 | monthly Q&A with Dr. Fung. Five years ago, Patrice and I had the opportunity, the honor, to interview |
| 1:21.6 | Dr. Fung, about his then newly published book, The Cancer Code. That was before these webinars became podcasts. |
| 1:31.1 | With October being Breast Cancer Awareness Month and marking the five-year anniversary of this |
| 1:37.2 | important book's publication, we thought it was the perfect time to revisit this crucial topic. |
| 1:48.0 | So, Dr. Fung, I'm excited to talk to you about the new bone broth. Yeah, this is very exciting. We've been working on it, Megan and I. |
| 1:53.8 | I got my son to help Matthew and his friends. So what we've done is, so I was just doing fasting |
| 2:00.2 | the other day and I thought, oh, I really needed this product. But what it is is a powdered bone broth. So I make my own bone broth normally. Okay. So I'm making some now actually, but it's a pain because it takes 24 hours. Actually, it takes me a little more because I throw in the chicken and then I throw in the salt and stuff, but I cook it for like 18 hours. |
| 2:18.9 | And then I stick in the fridge to take off the fat because I don't like it. So it's almost like three days from when I start the whole process. You know, and I do make enough so that I can freeze it. But it's a pain. So I find it very useful. But the problem is when you look at a lot of the bone broths that are out there, they have all this other stuff in it. You know, and that doesn't give you control over it. So, you know, we're talking Megan and I about how we're going to make fasting easier for this five day. Reset challenges and stuff, which I actually think are super, super useful for people to do because I'm doing them |
