I did a 25 day fast when I was in my 20's and I lost 45 lbs. I felt great. Now I'm 63 years old today and I am going to do intermittent fasting to control my diabetes and hopefully I will get rid of alot of health problems that I have acquired over the years, Wish me luck!

This five minute video completely changed my life on 1/13/2017. I have been living the Keto and IF lifestyle since that day. Lost over 100 lbs and have maintained my healthy weight for over a year now. Not to mention the overwhelming JOY! Thank you Diet Doctor and Dr. Fung!

I am a Buddhist and we can’t offer foods to monks after 12 pm. To until sun rise the next morning. 16-17 hours gap. This practice been done over 2500 yrs ago. For energy and mental heath.

IF has changed my life. I cannot imagine living any other way. I have never been healthier or felt better. I love your book!!

[SunnyIlha]

Oh man. It feels so darn good to not eat anything eleven hours. Being totally completely empty.

And, OH! To eat after that.
Is HEAVEN.

One of the good things of IF for me is that i appreciate tasty and healthy food better
Strange but true

This quarantine had made me gain so much weight. I'm prediabetic and I've been noticing new dark spot on my body. I'm worried for my health so I'm gong to try this 🥺

[krisiephillips]

I like the quote from the Bible about only fasting and prayer. This is a powerful truth.

Sad to see that nowadays, when it's free and spiritually good, people starts to laugh at you or don't trust you.
They prefer to pay modern medication while you got something free and natural.

Hi guys, I’m Lara and I’m Lebanese Muslim and I’ve just been attracted to intermittent fasting/Keto diet. Since Ramadan is coming soon i found it another reason to hit this combination. I’m 163 m 73kg and I’ll keep u updated with the results ❤️

I followed Jason Fungs advice and reversed my type 2 diabetes. Lost 28lbs and reduced my high blood pressure. Lots of people I have directed to Dr Fung have done the same as they had seen my results. My sister and ex-partner were the first to ask me what I did. I told them and sent them what diet I had created for myself. I always said look at Jason Fungs posts on YouTube First. I have put back on the weight after Christmas 2020, but I'm going to start again and try to keep it off. My last blood test only showed me as on the border of Type 2 so although I have put the weight back on I have kept eating very healthy food most of the time so this change was obviousy very important to the overall changes. I will start my excercise regime back from today. I shall get back to my intermittent fasting. I will also restart my daily weight, blood and blood pressure testing. Thanks Dr Fung.

It has done miracles for my arthritis. Now I am adding Keto to the mix.

I love fasting! It’s been a game changer in my weight control and over all well being. I didn’t think I could get through my 12hour shifts but I started slow, and now it has become my way of life in less just 3 months!! People need to be open minded about different diets and be willing to push past the fears, doubts and negative comments. Thank you dr for this wonderful video! Lol about Starbucks and Ronald McDonald 😂

I’ve read your book The Obesity Code, even summarized the whole book, then bought your Complete Guide to Intermittent Fasting, loved that as well.Now I am really ready to get going, just wish I could get my husband on board. Thank you Dr Fung for caring enough about people to do all of this. I really feel in my heart that you want to make a difference in the world. May our Heavenly Father bless you for your efforts.
