    I have a question -- i am diabetic this time i stopped taking medication i fill much better
    the reason is i am fasting . the first day i was fasting 72 hours after a week again i did the same
    thing i loose 12 lb with in 2 weeks. the way of fasting is no solid food but only water/liquid/.
    when i measure my glucose before fasting it was 300 after fasting it comes down 180 .
    is there a way of standard fasting system; like taking diet foods ones a day, ie.. salad i need your advice
    piease . i have been with diabetic for 16 years.

    There is no standard way of fasting, there are several different "methods". When you do eat, try to keep the meals low carb/high fat. We have many lchf recipes available!

    At 1:23, Dr. Fung says, "...Insulin...turns on lipolysis. You burn fat..."

    What is he talking about? Insulin inhibits lipolysis.

    Even our side censors comments. Why would
    Dr. Fung say, "...insulin...turns on lipolysis. You burn fat..."
    Why would he say that? Does anybody listen critically?
    Why, again, was my second comment about this removed?

    Why just take my comments down? Why not
    address my question?

    I am not sure what happened with your other comment but I did not remove it. I apologize for the delay in responding to you. I have reached out to others to find an answer for you. It may have been a misstatement and if so, we will work to clarify it. Thank you!

    I think he simply misspoke and missed a word – that happens to the best of us.

    Right before this sentence he was talking about lowering insulin, and I think at 1:23 he meant to say that again ("lowering insulin", rather than "insulin"). Otherwise it clearly makes no sense.

    Thank you.

    I’m very very thankful about this team of professionals, the world must know this truth; my husband is a type 2 diabetic, and we have struggled for 3 years to find a solution.... I Believe Dr. Fung has the answer.

    I just have this question.....my husband decided to stop insulin and metfomin.
    His sugar is an average of 430, can we bring it down with intermittent fasting and keto diet?
    About how long will take for sugar levels to go down????

    Thank you very much!

    Please don’t stop the meds. Consult your doctor first
  12. Kristin Parker Team Diet Doctor
    A blood sugar reading that high is extremely dangerous. Please do not discontinue medication without specific consultation and approval from his doctor. He can get started with keto and fasting but his doctor needs to know and will help adjust medication as necessary.

    so i did the 7 day fast it took the last day for my sugar to be 83 in the am. but i eat a sauage and avacado and the next day i was 143 and i only ate once. what am i doing wrong
  16. Maree
    wondering how fasting blood sugars could be lowered (currently between 5.5 and 6.5) during gestational diabetes to avoid insulin injections if day time sugars are fine?
  17. Karen
    Maree, I would suggest not fasting at all but instead eating a very low carb diet. And by low carb, I mean below 20 net carbs per day. This will definitely lower your blood glucose levels and keep the baby safe. There is a short list of people who should not be fasting and pregnant women and breastfeeding women are on that list.

    The second time he said increased insulin turns on lipogenesis i e storage of fat. The first time I think he meant decreased insulin turns on lipolysis. Perhaps a slip of the tongue? We all know what he believes because he has said it a million other times elsewhere. Decreasing insulin stimulates lipolysis ans increasing it causes lipogenesis.

    In November 2019, my hbA1c was 12.4 after I decided to go for a regular blood test which was 2 years overdue. I weighed 157kg at the time my blood test was done. The doctor recommended 2 metformins twice daily and to see an endocrinologist who might have to prescribe insulin injections due to my high hbA1c. That was a death sentence for me and I decided to change my life from that moment onwards. I started OMAD (One meal a day) and despite of the doctors recommendations, I only took 2 metformins everyday before the 1 meal. After 3 months, I went for another blood test and my hbA1c was 5.8 (Weight 137kg). I continued the OMAD and after 3 more months, I recently went for another blood test, my weight is 121.7kg and hbA1c is 5.4. I’ve been doing 10 mins of HIIT cardio everyday for 6 months which is very manageable. Not only did my hbA1c drop, my lipids and everything else is in optimal range now. I continue to take 2 metformins before each OMAD meal until I get to my target weight. The doctor was dumbstruck when he saw my results and said I’m part of the 1% who have achieved this. Thanks to Dr Jason Fung and others who teach about IF, my life is completely changed. The food I eat is also great and this lifestyle is easily sustainable for me. I feel energetic and great throughout the day.

    Hi I have medium body of 60kg and height of 165cm. I am type 2 diabetic. I am taking a one tablet of 30mg Gliclazide before breakfast and one tablet of 500mg metformin tablet after lunch. So far my sugar is controlled but I wanted to try this low carb diet or even the intermittent fasting to reverse my sugar level. Thanks for the help
