    Glucose management is WELL within the interests of a nephrologist.

    This is a curious line of attack. Fung isn't a bariatrician or an endocrinologist so he's not entitled to comment on those fields... well are YOU a bariatrician or endocrinologist by chance? If not, what right do you have to opine?

    When someone who doesn't have credentials in a field claims that they know better than people who do have credentials in that field, I think anyone has a right to opine that that's shady.

    Fung takes a kernel of something that's in his wheelhouse, extrapolates it out to the nth degree, over dramatizes the conclusion, and then uses his own "case studies" as "proof", or cherry picks research that seems to support his claims while flat out ignoring research that refutes it.

    And I'd like to add, as others have, that none of this is a knock on IF. It is a great plan for many people to get their diets under control. There are some theories out there that it has other benefits, which may or may not hold up to the necessary further studying and testing. And then there's a lot of miracle cure, click-bait science fiction out there about IF trying to cash in on it's current popularity.

    Dodging the whole qualification debate but if he is suggesting a type of diet combined with intermittent fasting to reduce medication to control T2D and it helps in any way, isn't this a good thing? I am assuming that the individual would either be under a doctors care or knowledgeable in how to monitor their insulin levels so they don't exceed levels that could cause harm. I am very anti medication so if I am told I need medication I will try any method possible to correct the need for it if possible.

    he has basically said that the test subject could quit cold turkey with their insulin even before they start keto. ... as for some not eating for 3 days and being diabetic could cause severe issues.

    You’ve answered yourself here. Fasting and taking insulin is FAR more dangerous than accepting higher-than-average blood sugars. Obviously if you’re going to start fasting you should quit your insulin regimen (as a type 2 DM patient). Hypoglycemia kills in minutes, hyperglycaemia kills in decades.

    um no he said that insulin in and of itself is dangerous for the body and the more you take the more you body needs more and more and it harms your body and makes your diabetes worse. I said they quit cold turkey BEFORE doing keto. but he said a person had to be fasting 3 days before they started burning fat which is WRONG as you burn fat in a deficit. and it wasnt my question I also said nothing about taking insulin and fasting either.

    I said STOPPING insulin before doing KETO,not IF or anything else. as for those fasting while taking insulin I would not suggest doing anything unless under the advice or a dr and one who is monitoring the patient closely.many do find fasting though for a short time do have improvements in their IR and their glucose readings,for some its the opposite. I also wouldnt suggest not eating for 3 days either.



    you have hypoglycemia and hyperglyemia mixed up. hyper means too much sugar in the blood and it can also mean ketoacidosis- https://www.endocrineweb.com/conditions/hyperglycemia/hyperglycemia-when-your-blood-glucose-level-goes-too-high

    -hypo means low blood sugar -hypoglycemia-https://www.niddk.nih.gov/health-information/diabetes/overview/preventing-problems/low-blood-glucose-hypoglycemia

    oh and as for one killing you faster than another. try being in a car with someone whos sugar gets too low and they start hallucinating and pass out.

    oh and both type 1 and 2 can kill you if left untreated .also in type 2 patients there is something called hyperosmolar hyperglycemic nonketotic syndrome that can happen as well.while in those with type 2 KA is rare it can still happen. neither one is something to mess with. and many here with type 1 have also done keto and got their insulin to a level that works for them in a healthy way. meds are another thing that can cause issues in those with type 1 and 2

    I think some criticisms of Fung come because people tend to forget that people with IR are his audience. If you forget that, it can come off that he is saying that insulin = evil for everyone because the main focus on his diet is to reduce insulin levels (through diet, weightloss and IF).

    Books like "The Obesity Code" seem to be marketed towards everyone with a concern about their weight, not people with a specific diagnosis of IR.

    Obesity code is marketed more towards everyone than the book we were discussing in this thread, which is called Diabetes Code.

    I think you need to re-read my post. I know that hypo means low and hyper means high. I don't know why you think you're teaching me that hypoglycemia is dangerous when that's exactly what I wrote.

    Let this be clear: severe hypoglycemia, no matter the cause, is life threatening and an emergency. Severe hyperglycemia happens for hours per day, for weeks on end, in poorly managed diabetics. One is far worse than the other.

    Hyperglycemia doesn't CAUSE ketoacidosis, it is a SYMPTOM of ketoacidosis (in a diabetic).

    if you do 5:2 which means 5 days of maintenance calories and 2 days of like 500 calories you are creating a deficit whether you realize that or not. Ive done IF all my life and I have gained weight,lost weight and now Im maintaining all still doing IF. I at one point stopped doing IF and was told eating breakfast would boost my metabolism. nope didnt lose any more fat or weight compared to fasting. no one is saying that IF doesnt work for insulin resistance. but you still need a deficit of calories to lose weight. IF works for weight loss IF you are in a deficit of calories, I am living proof that you can gain weight and maintain weight by fasting. all due to intake of calories.

    and a plateau is 6-8 weeks of no weight so did you go that long without any weight loss? you didnt lose weight eating more calories than you burned. you created a deficit. if you didnt eat at all those 5 days (which is not how 5:2 is normally done) that means you had NO calories for those 2 days and had calories the next 5 which means deficit. you may have ate more the 5 days but the 2 days with little to no calories means you were in deficit wich means weight loss happens.

    if you were in a true plateau and lost doing IF then you were eating more than you thought before you started if and eating less.

    I obviously did not communicate well, since there is so much you asked about - I ate MORE calories overall during a WEEK once I started IF. I was previously on 1200 calories/day (8400/week). I went on IF 5/2 - fasted 2 days (ate 500 calories dinner), on the non fast days I ate up to 2000 calories (11,000 calories/week). Did not change anything else. Broke my plateau. During that time I was weighing and logging ALL my food very carefully. I was discouraged to say the lease.

    you ate more overall but the deficit was still there. many people go by a weekly deficit instead of a daily one. they eat more on some days and less on others. its still creating a deficit so thats why it worked. if you didnt lose weight before IF and keto then you had no deficit happening

    oh and then there is this saying that hyperglycemia may cause ketoacidosis not that its a symptom Diabetic ketoacidosis (DKA) is a serious condition that can lead to diabetic coma. May be caused by hyperglycemia (high blood glucose) or hypoglycemia (low blood glucose) in people with diabetes http://www.diabetes.org/living-with-diabetes/complications/ketoacidosis-dka.html

    That link doesn’t say anywhere that hyperglycaemia can cause DKA. In fact that link has a section actually titled “what causes DKA” which says the following:
    Here are three basic reasons for moderate or large amounts of ketones:

    Not enough insulin

    Maybe you did not inject enough insulin. Or your body could need more insulin than usual because of illness.

    Not enough food

    When you're sick, you often don't feel like eating, sometimes resulting in high ketone levels. High levels may also occur when you miss a meal.

    Insulin reaction (low blood glucose)

    If testing shows high ketone levels in the morning, you may have had an insulin reaction while asleep.

    Even if you're insulin resistant, insulin isn't evil. That's like testing someone for a virus by looking for antibodies to the virus, and then blaming the antibodies for the illness. It's IR that's the problem, and consuming more carbs than your body, with its particular degree IR, can handle. The insulin response to blood glucose levels is not evil.

    I never said insulin is evil. I said it can seem Fung is saying IR is evil - mainly because he is constantly preaching about how to reduce it.

    I know for me when I was obese I was neither pre diabetic or IR. my daughter is very obese(she has a thyroid condition) and she doesnt have IR,and she is not pre diabetic either. she is more than 100lbs overweight.all her other health markers except for the thyroid issue are fine. no high blood pressure. nothing like that .she tried doing low carb per the advice of her first endo. it did nothing for her at all. not saying it doesnt work for others.she also lost no weight but then with her thyroid still not under control that may be a big part of why.

    my sisters are overweight and none of them are IR or have pre diabetes either.we were all thin as kids too and as we got older we started packing on the pounds. for me having my familial hypercholesterolemia,if I dont treat it with diet,exercise and meds I can develop type 2 and thats a route I do not want to go.many of the people on my moms side are heavy(even though my mom and brother were thin and my aunt was overweight,yet my granpa was thin and my grandma of a healthy weight) and only 1 or 2 of them are actually diabetic.I had a great uncle who was of normal weight and had type 2 but he didnt take care of himself so he was always"losing" body parts.

    a friend of ours was over 500lbs and weirdly enough he was not IR or pre diabetic but many in his family were. he had WLS and not sure what he weighs now(I dont ask). so I would say its probably a split amount of people who are overweight/obese who have IR or are pre diabetic. and the other half who dont have it. as for the ones that dont know they are IR or prediabetic I would say that possibly is a small percent as most of the obese/overweight people I know all go to the dr for one thing or another at some point.
