Dr. Stephen Phinney put together a three-part video series on ketogenic diets and nutritional ketosis. You’ll learn the nutrition science behind ketosis, what the research shows regarding its safety and benefits (including if and when you should obtain medical supervision), and how to troubleshoot your eating plan to optimize your ketogenic diet.

  2. Excellent. In trying to maximise fat consumption, what is your view on eating large amounts of animal fat on beef or pork? Can I eat too much animal fat?

    I am 3 yrs on low carb and lost 32kg. need to lose another 20kg but have plateaued a bit I think because of higher protein than I need.

    thanks for your efforts.

      Sources of saturated and monounsaturated fats should provide the majority of your dietary fat intake with a limited amount from polyunsaturates. Many animal fats are great sources of fat. More on saturated fat here: https://blog.virtahealth.com/the-sad-saga-of-saturated-fat/

  3. Very good and clear information. I like this way of eating and it makes me feel good and energetic. I have lost a lot of edema. My problem is the term “satiety”. I have had a problem with binge eating and probably have destroyed my feelings of satiety so it’s hard for me to judge. Often, I feel full but eat more, so even though my fasting blood sugars and HbA1c have improved, my weight has not. I am on the Virta program.

  5. Hi there
    I have a question I wondered if someone could answer regarding Lipids, Particularly TGs and HDL.
    Why when doing Keto and in Ketosis would your TGs go up, when they were going down and HDL go down when it was going up. we have about 25-30g carbs a day, about 70 – 100g of protein and the rest is made up of fats.
    TC and LDL have both gone up slightly, there is a problem with inflammation of the gums awaiting dentist work.

  7. Hi,

    I am Type 2 and living in the UK. I am doing my Keto diet on my own, my DR say I have to stop sometime and hoping to find someone in my city to help me stay on this diet. Lost a lot of weight, off my insulin and still on my tablets. The DR is ok with this but no guidance from them at all. On the National Health Service you really can’t get any dietary counselling that would endorse this. Enjoy these blogs.

  8. I’v been low carb for 2 yrs and lost 35 lbs and moved my HbA1c from 6.4 to 5.7.
    I saw you had canola oil on the slide with good fats. You also mentioned safflower oil for cooking.
    I though veg oils were toxic for cooking so what makes those 2 oils healthy?
    Thanks, I appreciate what you and Verta are doing!

      Thanks for your comment! Here’s an answer Dr. Phinney wrote up on canola oil: https://blog.virtahealth.com/canola-oil-keto/

      As for safflower oil, Dr. Phinney was referring to high monounsaturated versions (also called ‘high oleic’) of safflower and sunflower oils.

  10. Thank you so much! I’ve been planning on going on Ketogenic Diet for some time now but was skeptical about the safety of it because there is definitely a lot of misinformation on the internet. Watching these videos made me much more confident.

    I was hoping you would comment on kidney stones because I’ve seen some comments about Keto Diets increasing the chance of getting kidney stones, and it seems to be quite prevalent in my family. I have read some information defending against this point but would like to hear your scientific opinion on it, if at all possible! Thank you again!

      Dr. Phinney said,

      “Kidney stones have many causes. The most common chemicals found in kidney stones are calcium, oxylate, and uric acid. Significant promotors of kidney stone formation are genetic (aka inherited) factors, dehydration, and low dietary magnesium. Although serum uric acid levels go up in the early adaptation phase of a well-formulated ketogenic diet, this is caused by decreased excretion, not increased production. And after a month or two, the kidneys adapt to maintaining normal uric acid excretion. At Virta, we devote considerable attention to hydration, adequate but not excessive dietary sodium and calcium, and despite plenty of green vegetables, nut, and seeds (dietary sources of magnesium), we supplement magnesium when there are early clinical signs of depletion. Our clinical experience is that kidney stones are rare during a well-formulated ketogenic diet.”

  12. Thank you for the great tutorial.
    I have been in ketosis diet for about four weeks or so . My total cholesterol shot up from 6.6 mmol/L (above the desired <5.2) three years ago to 11.1 mmol/L today! and my calculated LDL went up from 3.62 to 7.74 mmol/L. I am quite lean, and not doing this for weight loss, but for other health benefits. My HDL is about the same, and my triglycerides went up from o0.85 to 1.44. I understand that for a few people total cholestrol and LDL can go up quite a bit. My question is are these elevated levels okay, will they normalise. I have no idea how to explain this to my traditional doctor. Thanks for any clarification
