I’d stop the fast. Think of it like this: extended fasters abstain from heavy lifting because it doesn’t build muscle so why would what you’re doing give different results. Plus, even though you’re a month post op your immune system and tissue cells are still working in overdrive rebuilding tissue and hopefully muscle from your P.T. Don’t risk it. You’re body needs all the nourishment it can get now. Good luck:)
I had Achilles surgery and my surgeon didn’t have an issue with intermittent fasting, but I’d guess he’d be against extended fasting. If you’re worried about maintaining muscle, the fast will not help. Recovery from surgery is a drag, and it’s not worth making that any harder than it needs to be.
Ask your doctor, s/he is a much more knowledgeable source with your best interests at heart.
growth hrmone increases by over one thousand percent during a fast so you will be fine. Secondly your body will only really eat up your muscualr glycogen/carb stores, then fat, then once all metabolizeable fat, such assubcutneous and visceral fat is one, then muscle is finally catablized. In order to reach muscl catabolising, you would have to be be fasting for significantly over a week. even if you are skinny, your body can us fat stors for quite a while. if you have more excess fat tissue than a skinny person, it takes even longer. you will be fine
