since ketosis is determined by liver glycogen levels and you burn quite a bit of liver glycogen while sleeping and since both anaerobic exercise and fasting deplete liver glycogen stores couldn't you theoretically consume say 250-500grams of carbs at night to fully replenish muscle glycogen (using starch based carbs) and whatever spill over of carbs enter the liver deplete that by morning after your workout due to a combination of the overnight fast, anaerobic exercise, and post workout fasting (if necessary) with the end result being that you achieve a state of ketosis during the day while still maintaining muscle glycogen stores for exercise in particular weight training
this would essentially be a radical variation of intermittent fasting where you do a fasted workout followed by post workout fasting and then protein/fat meal at dinner time then a carb load at bedtime

I am highly frustrated right now because I know I've seen a study in which they took long distance athletes, who were already in ketosis, and had them exercise until their muscle glycogen was depleted. They were able to eat a post-workout carb meal and then return to the levels of ketosis they had before. I still can't find that study. I just don't remember what it was called or what to look for.
Anyway, what would likely be necessary for this to work is actual blood ketone testing, and a low-fat low-fiber carb source. You'd want any insulin response over and done with pretty quick.
I wouldn't worry about liver glycogen levels, because the liver has a tendency to make glycogen and put it into the bloodstream for the brain to use. Since it is regulating blood sugar all the time, regardless of whether or not you are in ketosis, it seems to me worrying about the glycogen levels in the liver is pointless. Create the deficit in muscle, where you have some control over things.
I am probably not in ketosis, because I am not being that strict, but I have found this seems to work, according to the scale at least. I had not realized how important it was to keep the fats away from the carbs before.

You make some big assumptions. I think you better question those assumptions first. http://www.jackkruse.com/emf-4-why-might-you-need-carbs-for-performance/
You would also do yourself a favor to Read Ben Greenfield's last few blogs and see what he is doing now.
