For those with good blood sugars, a cold shower causes your liver to release glucose into your bloodstream, and your white fat cells to release lipids, in preparation for thermogenesis. So your brown fat cells are burning everything they can get: glucose, lipids, ketones, to maintain body temperature. Those in ketosis prior to cold exposure could very well see a temporary drop in ketone levels because the liver will replenish blood sugars faster than it will replenish blood ketone levels.
Ice bath affects on ketosis test for fun
and ice bath for fun! One poster said it it all----CAN NOT COMPUTE!
old thread but too funny and wow on that experiment, takes guts and glory I donāt have
Ahh I see. Thanks for the insight and if I have anything else to add through noticing something out of the ordinary from my personal experiments, Iāll be sure to share them with the community.
Like pretty much everything I suspect thereās at least some genetic predisposition as well. Those of us with the āpredispositionā burn everything available to keep the temp up via thermogenesis. My experience is that I will get hungry before feeling cold. When I start to feel cold itās because I didnāt eat soon enough to refuel. I suspect those without the āpredispositionā tend to add insulation rather than āturn up the heatā.
I donāt have the science on the genetic predisposition, but what youāre saying makes sense to me. My ancient ancestors are from the North Sea in Europe, and I live in Phoenix AZ. Iāve become convinced that I need cold exposure to maintain metabolic health because (for whatever reason), Iām not built for the desert climate.

This seemed pretty relevant to this discussion. Iām particularly interested in the part at the 12:15 mark where they speak of females doing one arm cold plunge therapy. Thatās all that Iām set up for as of now. Iām definitely finding that my glucose goes up after I sleep, workout & it seems even after eating too much protein. I know glucose is stored in fat and that protein can trigger a release but Iāve been insulin resistant for so many years, I guess that itāll take a year or more to reverse it & get consistent high ketosis/low glucose numbers after Iāve eaten anything. Iāve just started arm plunging so Iāll get back with my results.
So, plunge one arm only into an ice bath? That is a lot easier than finding something where you can get your whole body in.
Heck yeah man. Iāve only whole body once but hauling all that ice, etc was time consuming & heavy. Now it mentions females-which I am, & using the non dominant arm. I wish I could find more info on the study. But for now, 10 frozen water bottles & a plastic tote & Iām trying it out. Iāve been testing with my keto mojo-but Iām new at that too-only had it 3 weeks, so just figuring out when I naturally dump insulin has been tricky, plus determining if itās what I ate that spiked it or not, so I wonāt know if it helps me for a bit. Plus, I only lasted 15 seconds the first time, then 20, now 45 so Iām working my way up-lol This was the only place on the web I could find anyone talking about plunging & ketosis time correlations so I figured itād be a good place to post what I heard. Anyone else have any idea how long it takes from the time you plunge-ALMOST or lightly in ketosis, to get to a moderate or high ketosis & water temperature & length of plunge? Iām not against getting a horse trough if anyone has specific information that itāll helpš
Glucose going up in the morning is called glucose sparing. Iām still not entirely sure why the body does this, but itās common for folks on low carb. My blood sugar is highest in the morning and lowest right before bed.
My glucose goes up during exercise too, though supposedly lower intensity exercise like walking makes it go down. I havenāt tested that though.
I looked into getting some cheaper ice baths, but even a ācheapā one for the whole body isnāt that cheap, and then you have to get enough ice for the whole body. Iāll be interested to see if you notice anything with a single arm bath.
I stopped looking into this area after I realized it was too expensive and too hard to do a whole body ice bath. So, Iām not sure what effect this is supposed to have. I know Iāve listened to podcasts about this, but I think I blocked it out since I knew it wouldnāt apply to me.
Interesting, I havenāt been having ice baths but I have recently been swimming in our local lake which is pretty cold. To the point where my hands and feet started to go numb. Once home and after a warm shower and tea is seemed to take forever to warm up. It didnāt occur to me to check my bloods , I must remember the next time.
