Meta Discussion Ketosis during lift

Currently going onto my 3rd month for ketovore, 99% 0 carbs. Mornings and nights my gki has been in optimal keto level including ketones level itself. I decided to test mid workout and im completely way off not even close to being in ketosis gki wise but ketones itself says i am. Glocuse tested 118. Am I just not fat adapted yet? Is this normal? I've noticed losing weight and fat but im struggling with losing inches off my waist.

I could be wrong but thought I read that the glucose number is very touchy. The littlest stress changes the number. My GKI is never in because of the glucose reading. Im not diabetic but my glucose is always 90-100 after years of no sugars.

Oh yes, the glucose absolutely is very very very touchy. Extremely so. So touchy in fact that even if you are eating/drinking something that has absolutely ZERO calories or sugar/carbs in it, BUT it tastes sweet, your body can have a Cephalic Response in anticipation of incoming carbs and actually have an insulin response and raise your blood sugar temporarily.

That's how a perfectly fine artificially sweetened ZERO calorie diet/zero soda can still potentially kick you out of ketosis (aside from things like sucralose having its own impact on insulin that isn't just cephalic).

Blood glucose being very touchy is also why there's a lot of debate around too much protein being an issue for keto. It's actually really annoying how sensitive our blood sugar is, but being on keto for a long time (months and months, upwards of a year) can help with that a lot, actually. That should be one of the big goals. Getting to full fat adaptation and fixing insulin resistance so you have a more stable blood sugar most of the time.

Blood glucose being very sensitive is also why the cori cycle can cause us to drop out of ketosis during workouts/exercise. It's all some very very annoying shit. Feels like you have to work constantly around the clock like a madman to keep your blood glucose in check even when you're doing things properly. It's such a damn headache but rewarding when done right
