Welcome Simon I’m glad you could join us.
Depending on what your diet was before carnivore it could be oxalate dumping. If you were a big vegetable eater in the past your body could be trying to get the oxalates out of your body. Then again it may be histamine reaction. It’s hard to say. The way to find out would be to change your source of beef. Find a butcher or store that sources its beef from local farmers if you can. While you can’t always trust the labeling, try to find beef that is labeled as organic, grass finished. Histamine intolerance comes from beef that has been aged so in your case the fresher the better. while most people don’t have any issues with eating beef from Wally World is best to remember that much of their beef is imported from other countries, especially the ground beef found in tubes. In one package of ground beef there may be a mixture of ten different cows in it. Thats not necessarily a bad thing in and of itself but it may contribute to histamine intolerance.
I wish I had better advice for you but not having any real experience with it I can only go by what I’ve read. Give it time and good luck.
Btw, be careful about reducing your fat intake as that is your only source of energy.
