Theres one thing i still dont quite understand about ketosis you might be able to help with.
Today I'm in the middle of an intermittent fast. for convenience sake lets say my resting TDEE is 2400 calories. therefore I burn 100cal / hour resting. Last night, 8PM was my final meal. It's likely than after that meal I had totally filled my glycogen stores.
fast forward 16 hours later and I havent eaten anything so a good part of my energy consumption has come from glycogen. Lets say I've burnt up 1000 cals. 1600-1000 = whole body glycogen stores of remaining ~600cal.
I then did a combination of cardio and HIIT over the next few hours that by my estimation would've burnt about 1000 calories - still havent eaten. I have well and truly depleted all glycogen stores and are now burning primarily my body's fat reserves - I've been eating lowish carb for a year or so, and IFing for a few years so I'm pretty well fat adapted.
Why arent I now in ketosis? What is my brain living off?
Without knowing exactly where you are at and your ketone numbers it sounds straight forward, you are not yet in NK and you brain is using both glycogen and ketones.
You said "It's likely than after that meal I had totally filled my glycogen stores." so what did you eat to fill them? and if you are aiming for NK you dont need to do it anyway.
Also remember Protein is the hidden enemy of Ketosis, your fat has to be a bare minimum 75% of your macros. A good rule of thumb is 30g carb to start with, 1g per kg body weight of protein and the rest (75% or more)l fat. Above ground greens should fill you until you are full as a boot.
And as posted somewhere about Gaz carb loading for filling glycogen, remember he is Paleo not Keto.
