My experience with AF was different. After years of doing all kinds of Fasts (2-12 day, dry fasts, OMAD, 16-8 etc), I experimented with AF. For approximately 3-4 months I did AF with a 1800 Kcal refeed (1 meal). What I experienced was a lot of muscle loss and a messed up metabolism, always starving and feeling like complete shit. It took me about 8 months to fix. What I surmised is that with AF you don't enter a true fasted state but a gray zone, so it's more like starvation than fasting where a multi day fast (48 hours or more) seems to get you into a state that is muscle sparing.
