I'm parasite free for sure since I had to go through a lot of testing when I first started having issues years ago. Idk about Candida though. TL:DR; from doctors was "IBS" ie. we don't know but it isn't a known allergy or disease related.
I think I need to somehow make my eating day calories around ~4200 to average 2100 a day. That would probably keep my weight stable. I just can't figure out how to shove 4200 calories into a single meal (while keeping it pleasant).
