   His argument is not at all weakened by including the experience of religions with fasting. The point is to show that millions of people fast on a regular basis very successfully and without damage. And they have done this for hundreds of years. Thus, anyone can fast based on any reason they have used to decide to fast - whether religious or nutritional.

   There's tons of science to talk about as well, and he does, check out Jasons other talks – in high quality above or worse on YouTube – or his blog.

   If Jason ONLY based this on religion I would absolutely agree it's not enough. But this is only a 5-minute introduction and I think it's a good one. I don't mind that he spent a few minutes of it on the long history of fasting.

   There's something to well-tried experience as well. No matter what kind of modern scientific study you dig up it can never match the long term (thousands of years) or the massive number of people (hundreds of millions) of the big religions.

   If you can't advance beyond the first video in a series, then you probably need to become a member to see the rest. (It would be nice if it told you that instead of simply returning to the first video.)
   I resisted joining for a while, but finally did, and I think it's a great value. There's just a ton of new info added frequently, plus being able to ask Dr Fung questions directly.

   My daughter is 15 years old, She is diagnose with insulin resistance. Since she was 10 years old she started to gain weight, eating more was not the reason for this problem. She was premature baby (34 weeks). Her height is 5 foot and weigh 163 pounds. Is it true that being premature could be the cause of insulin resistance?, Is it ok for her to be on a low carb diet? Is she too young? Could she fast? Does she need to be monitored by a doctor?
   I cook from scratch, we tried to eat organic products as much we can, few processed foods. I have started to remove even more carbs and fats since 3 weeks ago She really doesn't eat much. I am pushing her to exercise. She doesn't loose weight. I am very worry. I don't know how signing up to this site could help me to get my daughter healthy.

   Just a tip. Use a teleprompter so that you don't have to look away from the camera. It's better to keep eye contact with us to better keep us engaged instead of looking down at your notes. Also, wear solid colors instead of something striped or checkered to prevent moire. Other than that, great info and thank you for putting this information out there. This is a wonderful site.

   Thank you, the first thing I thought when I viewed this video is "I finally found what I'm looking for, IT MAKES SENSE".
   I'm so impressed with your speech. It's fair and beautifully explained. Thank you for making the video for people like me. God bless you.

   I love fasting! All my life I have yo-yo dieted and my weight of course has gone up and down with it. Counting calories made me hungry and for some reason even when I wasn’t hungry I wanted to eat. And eat rubbish! I could binge on two pies, a king size block of chocolate, a bottle of coke and two cream filled donuts and it was not enough. Now I have learnt to fast it has changed my life. I can sit and watch my family and friends eat delicious burgers and other foods, which I love, and I don’t mind at all as I am fasting and choose not to eat. Combining fasting with LCHF has meant in the last two months I went from 94kg to 79kg! I was born with a heart condition and my cardiologist was so amazed at my weight loss he and other colleagues at the clinic have decided to try fasting themselves. I occasionally have something special as a treat, dark chocolate, a pie, or even a donut but I don’t make a pig of myself any longer nor do I desire to over eat and these things are just treats and not regular foods for me. My cravings now are for fresh green vegetables! I cannot praise fasting and low carb enough and I have paid nothing for this information. I simply found Jason Fung on YouTube by accident and then stumbled on diet doctor. Thank you for all the free help. It is changing peoples lives and for the better.

   I am in day 6 of the keto diet. I do not have a gall bladder and I am finding all the fat is creating havoc with my stomach. Nausea, diahorrea and belching. I have lost 2.5kgs in that time. Any tips on how to manage this?

    Jason Fung,

    I'd like to challenge you. You've made quite a bit of money on the premise that insulin is the x factor. Why don't you sponsor or lead the sponsorship of getting more foods tested and added onto the insulin index. I appreciate all the information you provide and this is not a derogatory comment but a challenge to take your dedication one step further.

    Thank you for considering.

    I don't see the point of this challenge : it's pretty clear that carbs are the main driver of insulin. People just need to stay away from carbs to see their insulin going down and that's a simple message !

    I'm just about finished reading"Obesity Code," and I must say that everything in that book makes TOTAL sense. I have been dieting since I was probably in my 20s, only to gain back the weight and then some. The perpetual hamster wheel that I've been on with the "eat less, move more" mantra, stands to reason why I've NEVER been able to keep the weight off. So far, I'm a believer. Thank you Dr. Fung (and to my own doctor) who turned me on to this.

    Sharon, That is going to vary from person to person. Many people find they have the best results with only black coffee.

    Why does the advice here suggest artificial sweeteners are ok when Dr Fung's book explains it's detrimental effects in detail. Artificial sweeteners produce a large insulin response and break the insulin lowering effect of fasting, according to the book. Can someone please clarify this for me?

    Monk fruit is not an artificial sweetener, it is natural. You can read more about our 3 approved sweeteners here - https://www.dietdoctor.com/low-carb/keto/sweeteners#top3

    Dr Fung says that water, tea and black coffee are acceptable during a fast.

    what foods should you avoid when breaking a fast? Also is it different if you fast only 24 to say 3,4 days of fasting?

    Thank you for this info, Really Love all that ive read on Diet Doctor. Ive been keto for about six weeks and initially lost weight, but now i have plateaued, which I’m sure is due to Leptin as I have high Leptin in blood tests. I am trying intermittent fasting, but how do I control the hunger pangs which are really bad at the moment? Keto is supposed to stop these and you don’t feel hungry but some days I’m ravenous. Help :). Thank You

    As your body adapts to a ketogenic diet and you consume meals that are very low in carbs, have adequate protein and fat added for satiety, hunger should be minimized. Check out our guide to hunger for considerations about your hunger and how to determine next steps. https://www.dietdoctor.com/low-carb/hunger

    Just under 2 weeks of doing OMAD and I'm already down 6 lbs. I had lost 11 lbs after 4 months of Keto but plateaued so I decided to look into intermittent fasting and came across Dr. Fung's videos and articles. It all made so much sense, there was science behind it and he wasn't trying to sell anything. It got me over my misguided idea that fasting would destroy my already sluggish metabolism, so I tried it. I'm now amazed at how efficient my metabolism has become and all the energy I have. Being postmenopausal and about 70 lbs overweight I have renewed hope that I can finally take it off!
