My opinion is you were eating TOO MUCH protein, and it was not getting digested and causing gas/bloating/brain fog etc. While unrelated to Candida these symptoms mimic it very closely.
I can mimic those symptoms if I eat meat within 2 hours of bed time.
This is my personal experience, and opinion, but I'd suggest doing a test run of protein for breakfast/lunch then veggies and something light for dinner.
Eating a lot of meat especially a meal before dinner w/meat will puts stress on an already stressed digestive system like those found in Candida suffers.
Again just my opinion, and experience but I mention it so you could potentially test it and see if it's candida or the meat/fat.
Once you STOPPED the high protein/fat diet within 3-5 days were you back to normal ?
