Question is as posted. Years ago messing around with a very high protein/low carb/low cal (PSMF) diet I would get woozy after workouts and squirt about a tablespoon of honey in my mouth post-workout to "clear my head". This did not affect my ketosis, but argueably a small tablespoon of sugar over the course of a day where meals are protein powders and chicken/tuna wouldn't really be enough to kick a person out of ketosis.
However, I would like to have some understanding to see if an individual, properly fat-acclaimated (as I am, I get tons of energy eating fats currently) and in ketosis, would have any problems downing some sweet potatoes post-workout.
I know currently if I have a "meat and potato" meal, my next day tends to result in a carb flu, but I've yet to experiment post workout.
