Hey, I love If and EF. I'm 100% sure that the right way. But I see quite a few people hate on it and specially on Dr. Jason Fung. It's quite frustrating to people tell you you're stupid for believing...
I'm interested to hear what the overall take on this from fasters who understand the hormonal impact of fasting on the body. Dr. Fung rarely qualifies this statement and uses black and white terminology such as "the CICO theory has...
Books can help a lot of you with the tips and tricks they contain. Here is my selection, hope it's helpful: * ***The Scientific Approach to Intermittent Fasting.*** Dr. Michael VanDerschelden. September 9, 2016 Dr. Michael VanDerschelden is a Doctor...

Received this email today from Dr Fung: Fasting and COVID-19 A lot of people are worried about how fasting affects the risk of COVID-19 virus infection. The truth is there is no good information on this subject at all, so everything is...
EDIT: Alrighty, everyone, that's a wrap! Thanks so much for the excellent questions. If you have more questions, check out the Fasting FAQ at my website, https://www.stevehendricks.org/fasting-faq, which has about 10,000 words of answers to the most common questions I...
So I know that Dr Fung believes in not calorie restricting (at least that's the only info I've been able to find). He says if you do a smaller eating window every day, you should still get the same calories...
I am currently reading *Why We Get Fat* by Gary Taubes, after having just finished *The Obesity Code* by Jason Fung. I'm about 40% done with the book and while there are striking similarities (e.g., fat accumulation is a symptom...
Hi- quick question to everyone who read Dr. Fung's Obesity Code: What did he say about weight loss and breaking long term fast? I know that after day 3, we burn our fat and maintain good metabolism. I am so bored...
I have read all of Dr Fung's books and watched various seminars. There is something I am confused about and which I'm hoping someone can help me with. He talks about his patients doing extended fasts in order to lose weight...
For example, sometimes my family will make ice cream (generally healthier than store-bought, but still, it's ice cream) and I know it has added sugars etc. It's hard to completely stop participating in any desserts with my family, so is...

I recently read and enjoyed "The Longevity Solution," a book Dr. Fung co-wrote with Dr. James DiNicolantonio. It expanded my understanding of the tension between growth and longevity, and dug into some theories of health that went beyond insulin, obesity,...

Has Dr. Jason Fung provided his opinion on the Snake Diet (and/or on rolling 48s, 72s, and 96s)? I'm *very* interested to know what his thoughts are. I'm not exactly following the Snake Diet, but I've recently started a 2MAW...
This isn't specifically related to Dr. Fung, but I wanted to let folks know, in case they didn't already know, that the r/loseit subreddit is **actively hostile** towards any discussion of intermittent fasting that is for a period longer than...
I've been surfing at /r/diabetes lately, and I've responded to some posts with "type 2 diabetes can be reversed. Try a low carb diet and fasting. Check out Dr. Fung on youtube and his website." I haven't gotten into any heated...
He mentioned not overeating, like just eating one meal and slightly more, don't try to compensate on breakfast lunch and dinner on omad. Just one meal and a little more. Does he actually mean we get to eat something like 500-600 calories?...
Edit: "This video has been removed by the uploader" Original post: This cringey spam video was uploaded 6 hours ago. Let's dislike and report the video as spam before people get taken advantage of. Hopefully Dr. Fung will see this and remove it...
I realize that although I’ve had some success with IF, I don’t REALLY know what I’m doing lol. I want to learn more about the science and how to maximize weight loss doing 16/18 fasts. I snack a lot too,...
From my brief research, I see that people say xylitol doesn't raise blood glucose or insulin, but I don't recall Dr. Fung mentioning it in the sweetener section in his book The Obesity Code. The reason I'm asking is that...
I genuinely thought whole milk will break a fast however, I am reading the complete guide to fasting by Dr Jason Fung and it seems to list whole milk as something you can add to coffee. Here is the list...
On keto when insulin is low, in theory, it circumvents to 2 compartment model so the body can access its fat stores. However, despite having fasted 20 out of 60 last days (OMAD on eating days), I've actually gained about...
Hey all. Ive been practicing IF inconsistently for the past two years and am really trying to commit myself to being more consistent about it this year. I recently re-read dr fung’s complete guide to fasting and there is a...
I've decided to make some changes to my lifestyle and eating habits and educate myself so I'm looking to buy one of his books, one that contains all the necessary information. I might buy more later but I need one...
Dr. Jason Fung promotes fasting longer and fewer meals to increase insulin sensitivity. My understanding is that the way to increase insulin sensitivity is to reduce your total insulin secretion. Why would one meal/day lead to less total insulin secretion...

Hi Everyone, After read both of Dr. Fung's books on fasting/obesity and buying his cookbook, I have been fasting for about 20-24 hours a day for the past 2 weeks. I'm liking it a lot. I have one question about BMR....
I'm just worried it's outdated, since it was written 9 years ago. And Jimmy Moore helped with it, and he's... um, a famous weight loss failure to be honest. ​ Cheers for opinions.
I'm wondering if anyone has had any luck reversing PCOS and/or insulin resistance on a particular type of fasting schedule? OMAD, 16:8 or extended fasts for example? I've been insulin resistant for 15 years and started fasting a few days ago...
I had never been committed to diets or sports before. I once tried the most common way to lose weight: eat less, move more. I dieted, I took up some minor exercise and walking for a few weeks. My weight...

Hey everyone! I’ve read through this sub’s wiki/faq and understood that anything with calories essentially breaks a fast. Then I listened to a video by Dr Fung that having some cream in coffee is ok during a fast? I use...
I'm 55 years old, male, reasonably fit. Diagnosed T2 diabetic in 2019 with an A1C of 7.9%. Found Dr Jason Fung while researching T2 diabetes, quickly moved on to OMAD and dirty keto which I've been doing for the last 2...

How does Dr. Fung go about transitioning a type2 patient from traditional insulin-based treatment to his low carb/fasting protocol? It was easy for me because I wasn't taking much insulin. About 2 months of low carb and OMAD and I'm down...

I really like OMAD because it's consistent & is an easy habit to get into. I'm sure I could just eat like this forever, until I hit my goal weight.

In this video https://youtu.be/T7o_hF1XB84 doctor Jason Fung mentions that ketosis begins after 2 days but many place I read it starts after 12-14 hours. What's the correct answer?
Hey everyone, I wanted to create a post because I feel like I have seen a bunch of posts recently from people who have started fasting to lose weight and are struggling with either not losing any weight, or plateauing very...
I notice DR. Fung mostly recommends alternate day fasting such as fast for a period of 24or 36 hours every other day of the week. Somewhere I remember him saying eating once per day would cause a person to plateau....
I've been on and off fasting over the last two months. Both intermittent and extended (about 4 days'ish). I learned about it from Dr Jason Fung. I find it doesn't seem to matter how I eat coming off of a fast,...

I find stuff like this interesting. This youtube video was posted around 5 years ago on youtube: https://www.youtube.com/watch?v=MzrYOPENuHY It's a woman who was losing weight by eating just 1 meal a day (unknowingly fasting). She was doing well. Then, as she says...

Hi, I was wondering if anyone had stumbled across any documents/literature by Dr. Jason Fung relating to fasting and Endometriosis. I couldn't find any. I found some on PCOS.

Hi, so I heard doctor fung talk about how fasting for periods of 3-4 days won’t slow your metabolism. He showed a chart of someone’s metabolism when on a traditional low calorie diet wich included carbs compared to someone fasting....
I am pretty new to this, and understand that dietary fat will not create an insulin response. Hence, Dr Fung has said that a "bulletproof coffee" "fast" (a couple cups a day, to prevent hunger) will not reduce the...

How did you present this to your doctor? I want to start a regime that will work for me but I need to be cautious since I am on Metfomin. Have you found that you had to find a new...
In one of his sample 24 hour fast protocol, Dr Fung has cottage cheese on the menu for breakfast on a non fasting day. Made me wonder....does cheese raise Insulin?
Let's say I'm doing a 16:8... Do I eat what I would normally eat in a day/the same number of meals in that 8 hours? So three meals? Or cut out a meal? (I understand the concept of calorie deficit - let's...

I've seen Jason Fung say that keeping the refeeds in between rolling are best kept keto. I'm a vegan. Does this mean I should just eat a lot of avocados and then go back out into the next rolling fast?
Pretty much what the title says. I’m planning to do an extended water fast (with electrolytes/vitamins) and wondering if anyone else is planning to do the same? Would love to have someone to chat with during this. Additionally please feel...
