Alcohol suspends ketosis.....when the alcohol is burned off....ketosis resumes. Does not "knock you out" as if you were to eat a high carb food (like a piece of real chocolate). You see this because getting "back" into ketosis can take you 48 hours or more whereas the suspension gets you back as soon as alcohol burns off...usually a few hours.

BUT alcohol will slow down your fat burning....because each one of those "suspensions" sets you back a day.
