Mammal meat allergy (MMA) is very uncommon. Uncommon enough that I’d be shocked if you and OP had it. Regarding your keto struggles though, feel free to make your own thread in the newbie section (you don’t have to be a newbie to get help) with your stats, food intake, medications, etc so we can try to help you tweak to see the changes. And, this information below might be of use to you.

Thanks for the link @J_A-M.
Unfortunately MMA is becoming more common on the east cost of Australia where I live.
To be honest, my symptoms don’t qualify as severe but are definitely noticeable.
Only way to tell will be through testing.
It is something I am considering.
If you do get an allergy test and learn more about how you’re reacting overall, I’d encourage you to make a post in the Progress n=1 forum. As I said, an allergy like that is fairly unique and having celiac (while obviously easier to manage with keto) is also unique.
