I’ve been doing IF for 10 months and never stopped my regular binge-drinking on Saturdays. I still have had great results from IF. I do tend to stick to vodka lime sodas and only start drinking after a nourishing meal. 34F for reference.
I fast 16:8 religiously but I do allow myself the occasional whisky during my fasting window (preferably scotch). I could see this being a problem for someone who drinks alot but for me I rarely drink.
PS my one other cheat that I allow myself is a low calorie pre workout drink (like a C4). Other than that no other cheats
I usually only have an alcoholic drink on my weekends, and then it could be a variety of mixed drinks, beer, or wine. I generally have 2 on those days, and my fasting period is much shorter as well (14:10).
I do drink but limited to only a few choices. I generally either drink straight bourbon or whiskey, gin and seltzer, or red wine. On very rare occasions I have a beer, but that’s probably only two or three times a year when I end up at a brewery and beer is all they have.
