Thanks for all the replies guys!
I kept testing and found some verrry interesting things. CampCook, I think you are right. My fasting glucose levels are much lower than "recommended" because I am very ketoadapted (I've been in ketosis for 3 months now with only 2 breaks at 5.5 week intervals for 1-2 days due to a cheat day). But I don't get hungry anymore and even when my BG is low, apparently my body regulates the amount of glucose it needs. No more no less. And it is around 65 because I run on ketones!
I tested all day yesterday and food only raised my fasting level of 64ish to about 76 max. Woohoo! But then, I did P90X plyometrics about 2 hours after eating my last meal. I was down to my baseline of about 64 again before I started. I let it get to fasting because I wanted to test Dr. Phinney's statement on one of the JM podcast that exercising while keto adapted usually has the affect of making someone LESS hungry. Well I can tell you, after the workout, I felt... unusually energized and still satiated. And p90x plyometrics is one of the most intense workouts I've ever experienced in my life. It is VERY intense. Very HIIT like. I tested my blood glucose right after finishing working out. And guess what. My BG shot up to 110! Thats 5x more than food make my BG go up. Still under very safe levels though. At first I was nervous that I had a big insulin spike as well (I wish there was a way to test this at home). But this test proved that the body DOESN'T need oral glucose to fuel INTENSE athletic activity afterall. The body's response to growth hormone and adrenaline speed up the gluconeogenesis process, created more glucose for energy and more ketones at the same time (at least this is my speculation). Honestly, before low carbing when I did this workout, I couldn't make it through the entire thing. This time, I felt like I could go for a light jog when I finished. Yay for this lifestyle!
Anyways to ease my mind about possibly having an insulin spike due to exercise, I researched. And found this article (can't find the link I'll try and dig it up in a bit). It was saying that blood glucose may spike during intense exercise but counter intuitively, insulin levels drop. So it was this odd X shape on the graph with glucose going up and insulin going down. And it stated that insulin isn't required for glucose to be taken up into muscles, there are other means of doing that. Free fatty acids are released, gluconeogenesis is ramped up to fuel the workout, and a whole bunch of other stuff was happening.
Anyways, within 2 hours right before bed, my BG went down to 70. Not sure what this signifies
. Maybe I am becoming more insulin sensitive after all and it had no problem clearing my BG.
I woke up this morning to find I was at 61. I checked 2 hours after waking up on the way to Easter service and was at the same. I had a dry (light milk) cappuccino and 30 min later I was up at 79 (not sure if it was the caffeine, or the milk, or a combo that made it go so high - I am going to do a control test tomorrow with black coffee after fasting). An hour later I was back down to 61. These numbers are lower than yesterday. But again, I feel totally fine, no hypoglycemic symptoms. And trust me, I know what that feels like to "hit the wall" and feel like you are gonna pass out from hunger/shakiness in my pre LC days. As mentioned, I think my glucose requirements are very low now since I'm pretty ketoadapted.
Anyways, I'm cooking a nice prime ribeye roast with all that goody fattiness for Easter tonight.
Then I'll workout and report my weird glucose rise once again
