Listen to your body when fasting, and work up to longer fasts don’t try and do too much too fast. If you’re healing a problem like that you’ll want to really monitor how your body reacts to go back to eating. I suggest getting a notepad and document all your symptoms and how they go away and come back and reactions after you eat certain foods. I highly suggest not going plant based and to use high quality animal products .
I had something similar happen to me in my life and fasting also healed it. I have one rule, I don’t eat after 7:30pm. I wake up and some days I push that out to one meal only but many days I eat about 12-16 hours from my last meal and do a workout then eat 2-3 more meals through the day. I make a huge focus on frozen and fresh veggies. I’ve given up dairy 6 -7 days out of the week. I try to give up wheat but it’s hard. I’m allergic to soy, it makes me very upset. You wouldn’t like me when I’m very upset. So I don’t eat it at all. And I only drink water. Usually alkaline since it’s got a sweeter taste and kicks my mood up a notch by the end of the working day If I’m consistent. I take probiotics and I take a daily supplement and I can’t help but feel amazing when I give my body time to do it’s thing in between meals and make those meals as nutritious as possible. I say screw the doctors, if what you’re doing is feeling good/healthy and it isn’t because you’re dosing yourself with chemicals (sugar,caffeine,drugs) then more power to you!
