Honestly I was more wondering about the 48 hour fasts. At first glance, I'm assuming it might impair recovery over the long term if the regimen is high enough intensity. I would assume if you're in more of a maintenance mode it could work better or even in a deficit
I don't train particularly hard and mostly just do cardio stuff, like lots of pushups daily.
Based on what I have experienced I think it's fine provided you're still maintaining an overall balance in the long-term. As in, on the non-fasting days you're eating enough of (if not more than) everything your body needs for your training regimen.
