Dextrose in post-workout shake on keto?

[Deleted member 33117]

Alot of the top minds on the ketogenic subject, inlight of new research, no longer believe that it is ketosis that makes the diet work but more the caloric deficit that is created and the refeeds that aid to replenish leptin levels.

There is the fact that when in ketosis, one expells alot of unburned fat calories int he form of ketones in one's urine, feces, breath, sweat, etc. Ketosis AIDS in creating the calorie deficit by its very nature.

IMO the amounts expelled throught these methods would have no significant impact. Alot of research indicates that just because you are turning the ketostix the darkest purple possible does not mean that you are burning more fat. In fact it is better to be showing trace amounts of ketones.(stix are not good measurement of ketosis IMO though either)

No signifigant impact? I think not. The impact is huge when one takes into account the ketones expelled of the course of a month, and the corrisponding fat calories they represent.

I stand corrected. Was just doing some reading and and the number of calories lost in the urine as ketones amounts to approximately 100 calories at the most, adding in those excreted throught the breath and through other sources it may be a little higher. Now for one day this is not much but over a period of a month (as you pointed out) can have a significant impact.

Thanks for the info BBF.

I found this very interesting.

" Higher levels of urinary ketones seem to be indicative of slower fat loss. Individuals who maintain trace ketosis seem to lose fat more efficiently although there is no research examining this phenomenon. A possible reason is this: high levels of ketones in the blood stream raise insulin slightly and block the release of free fatty acids from fat cells. This seems to imply that higher levels of ketones will slow fat mobilization."

Interesting, but again not real research, and this could vary from individual to individual. Where did this paragraph come from? Ketones do not cause an insulin response to my knowledge though. If they did, it could be an issue, though maybe not. The slightly elevated insulin level in a state of ketosis could lower blood glucose levels slightly, thus requiring the body to rely more on ketones as a fuel source. On the other hand, it could block the release of fatty acids. Its debatable. There is some evidence that deeper ketosis does increase fat lose in some individuals, but not all. None the less, this is still interesting, and worth looking into.

This came from lyle Macdonlds " ketogenic diet", this is news to me also, thats why I found it so interesting and had to post it. I missed that the first time I read it through.

I don't have access to a scale... is 40 g of dextrose equivalent to 1/4 cup? I did a "google" search and that's what I've come up with...

the C in CKD, meaning cyclical... is referring to the refeed day. Personally, I get kicked out of keto even with too many green beans.... approx 20g´s very low gi net carbs... If i were to consume dextrose, it would defeat the purpose of a keto diet
