    I lost not only 57 lbs, but also skin disorders, neuropathy, asthma, GERD and high blood pressure. ****** I just got back from my eye doctor. My retina has healed cotton wool spots and damaged blood vessels (in the last year) that had been present for multiple years prior. ***** I know I sound like a total snake oil salesman but there is no way around it. I can barely believe it myself. And I'm not even that strict on the keto; my ketones are 0.4 most of the time and I cycle in and out of ketosis often (I eat a lot of fruit and carrots). I also can't be sure my results are due entirely to the keto diet because I also do intermittent fasting as well. What I can say for sure is that I have never seen this kind of health response to a "diet" before and I've tried countless variations of high carb/low fat diets.
    So, in summary, I'm on the fence with dietary ketosis but I'm fully on board with low carb, high natural fats and intermittent fasting. I have multiple, well documented, measurements that prove that, for my body, a low carb diet, coupled with fasting, exercise and weight loss can heal degenerative disease.

      Last time I had an eye test I had a similar experience. My optician also was slightly surprised as my eyesight had an fact modestly improved. I'm astigmatic and additionally in my 40's at the point where often near eyesight also starts deteriorating, she was slightly surprised that there's no sign of this and that in fact my eyesight had improved. This correlates with me starting a ketogenic diet now some 2 years ago. (Additionally people have commented that I appear younger than I actually am. My skin and face is a lot more youthful than it was several years ago.)

      Ketosis is not a magical condition it's just a label given to how much ketogenesis happening in your body and how many ketones are in your blood. It's just your body's natural way of using fat for fuel in the absence of eating carbohydrate, so if you're on board with low carb, you should automatically be on board with ketosis! You have to get your energy from either carbs or fat so if you're not getting it from carbs then you you're going to be in ketosis at some point especially if you're doing intermittent fasting, otherwise you'd starve!

    I love keto. Its been a consistent for ten years. But I cannot stay in ketosis for longer than a few weeks or I become almost manic. Meaning I am soo high energy and so efficient that I don't sleep for more than a few hours a night and I feel very wired. This is why I began intermittent keto. 7-10 days, cheat and repeat.

    If you sweat a lot, exercise or get dehydrated - check you potassium. I ended up in hypoKalemia due to this on the keto diet. Now I add a potassium salt to my cooking.

    Open question to the group: does home-made chicken bone broth have dangerous or concerning levels of lead? I would enjoy making this without the risk of lead toxicity, but have heard others, like Dr William Davis, warn that chicken bone broth is too high in lead to be considered a good idea.
    I'm interested in getting adequate potassium in my diet. Does anyone have success using other forms of potassium supplementation, such as potassium bicarb or potassium chloride?

      Once the body is keto adapted, you become efficient at using fat as your primary fuel. This post explains how adaptation works: blog.virtahealth.com/ketone-ketosis-basics/

    Moving to a ketogenic diet (KD) is a significant jump from the standard American diet - time restricted eating/intermittent fasting (TRE/IF) can help control hunger and advance satiety sensitivity which is important for Type 2 Diabetics (T2D). The use of healthy fats and avoidance of carbohydrates/sugars in a ketogenic diet can advance satiety and limit caloric intake/glycemic load.... electrolyte mineral nutrient monitoring (EMNM) is the most important risk factor in fasting and in the ketogenic diet. The ketogenic diet is more difficult to support in *food deserts in North America* . Shifting a T2D metabolism with a KD takes time but can be accelerated when used with TRE/IF but requires EMNM to prevent the risk of refeeding syndrome.

    22:21 - 'There is some carbohydate in protein foods. When an animal is slauhtered there is glycogen in the muscle.' At the 5-10 grams per day Phinney estimates, this is negligable. However, it is my understanding that the glycogen in the muscle meat of animals is quickly converted to lactic acid. Does anyone out there have info or references on this??
    Most muscle meats were traditionally hung in a cool location for awhile before being consumed. Beef that has been aged for a month or longer is a hot 'new', but really old, trend.
    Organ meats, on the other hand, are best fresh. Or frozen immediately after the animal is harvested.

    9:40 if I'm already in ketosis from a low carb diet, does that mean I shouldn't intermittent fast so as not to reach "starvation ketosis" ?

    • @yvandaniel8050
      @yvandaniel8050 4 роки тому +1

      for diabetic people in crisis, "starvation ketosis" is usually associated with high glucose levels. That is not the case for healthy persons since the glucose is low. High ketones might render the blood/body slightly more acidic. Vegetables and/or carbonated water can compensate for that. So, there is no danger associated with high ketones if glucose is low: www.virtahealth.com/blog/ketone-ketosis-basics

    Dr. Gundry claims a Keto Diet is not recommended for those carrying the APOE4 allelle(s) - has anyone studied this?

    • @VirtaHealth
      @VirtaHealth  6 років тому +10

      Hi Sherri, thanks for your question. The human research data on this are spare at best. Dr. Gundry is a cardiothoracic surgeon who has published papers and books about the risks of plant-based lectins and coronary heart disease, but he has published no peer-reviewed research on the topic of ketogenic diets. Based upon this review of the literature, his views on the interaction between the ApoE4 allele and nutritional ketosis should be viewed as a hypothesis until proven otherwise.

    • @ldean8360
      @ldean8360 6 років тому +15

      I have a fitbit as a first approximation, but my best strategy is to weigh myself every day. If I'm out of my 3 pound window I make an adjustment. Using this method I never have more than 2-3 pounds to deal with. (I recently lost 57 lbs, so I have first hand experience with obesity and pre-diabetes). Maintaining weight is much harder than losing weight. On a keto diet losing weight is basically a no brainer.
      In my opinion the main benefit of a keto diet is that it facilitates fasting. Fasting was key to my weight loss. I am older and my system has been seriously damaged by the conventional nutritional advice of the past 40 years. I may never be able to eat the "normal" three meals per day no matter what the composition. This is not so bad as it seems. I spend far less time dealing with food. That's time I'm not cooking, cleaning dishes etc....

    • @donaldreitsma6419
      @donaldreitsma6419 6 років тому +1

      That's a good question and if anyone thinks they know then they don't understand metabolism, because it vares. Having said that, it is not about counting calories. Keep carbohydrates at 20g or less per day, 1 - 1.5g of protein per kg of lean mass ( used you target weight) and then eat enough fat to be full. DON'T COUNT CALORIES!

      @@ldean8360 I appreciate what you are saying and congrats!! I have Fitpants and Fitring. I don't weigh myself very often. Close to you, I lost 50 lbs and had all the metabolic syndrome markers which are now gone. I am now up and down around 45 lbs less because that's where my body wants to be. I don't worry about a weight window because I maintain a fairly consistent diet and eat to satiety so trust my body to know what's right for it. If I gain or lose a few lbs (some days it is up to 4 lbs a day!) it is probably due to water and the tell tale sign is how tight my wedding ring fits (because I did test against weight and seems to be a correlation). I mainly go by how my pants fit. LOL!
