Quick question, do I need to worry about the low blood sugar measurement?
And are these measurements proof that I am ketosis? Would blood sugar go down as ketones go up or how do they “correlate”?

No comments on this?

From what I understand, even in ketosis, your keto readings can be all over the place so I’m not sure it’s worth looking at besides to confirm you are indeed in ketosis.

I use a blood glucose monitor but I don’t know how your number correlates with my monitor which measures 0-300+

I will say that on my urine test strips the directions indicate ketosis. Did your monitor come with that information?

A ketone measurement of 1.8 means you are definitely in ketosis. The definition is a reading of 0.5 mmol/dL or above.

As long as you feel all right, a low glucose reading is not a problem when you are ketotic. The brain does just fine metabolizing β-hydroxybutyrate instead of glucose, so your glucose level can drop quite low without causing a problem.

Dr. Phinney talks about a friend of his who was conducting a study on some fat-adapted athletes. One afternoon, the researchers decided to manipulate the athletes’ glucose levels, and drove them down to levels that ordinarily cause coma or even death. As Dr. Phinney put it, “The only people who were sweating and having palpitations were the guys in the white coats.” The athletes were fine. Of course, the researchers eventually realized that what they had done was highly unethical, but the story at least illustrates that the fat-adapted body behaves differently from the sugar-burning body.

Thanks, could this measurement also indicate that I am fat-adapted? I could add that I prefer and think about fatty food when I am hungry and do not even miss carb food or think about it. When having days working out (usually every day), I have a good energy level (as in for two weeks ago), and I am not feeling hungry before I actually eat something. I do IF or 23:1 but the problem to me now is that I do eat a lot in this one meal a day. Way over my calories for a day. I am considering spreading my meal in two or three.

“…quite conveniently, they realised this once they had the results they were looking for.”

Pretty sure that’s how that ends :slight_smile:

Well, they ran a terrible risk, given what they knew at the time, but on the other hand they discovered something valuable.

I remember seeing a lecture in which Dr. Westman complains that no review board will authorize an experiment to show the benefits of a true low-carb, high-fat diet, because a high amount of dietary fat is “known” to cause cardiovascular disease, so such an experiment is ipso facto unethical. So you can’t prove the dogma wrong, because the dogma makes any experimentation unethical. The Stefannson/Andersen experiment would probably be considered unethical today, despite the number of documented traditional diets that were almost exclusively meat-based.

Fortunately, we are reaching the point where so many people are doing LCHF/keto with no ill effects that the review boards will eventually have to change their tune.

Maybe. Universities are hide-bound institutions (much as I love them).

The key is: do you feel bad? If not, it’s ok. On the keto hacking md podcast, 3 of them went on a week of fasting, and 2 of them got really low blood sugar values but felt fine. Even Jimmy Moore got into the 50s.
