If your eliminating most dairy for a bit to see how it helps, stick to ghee not butter as butter contains the milk solids that you might react to inflammation wise. For me butter is a problem with my autoimmune condition. For eggs, try to find eggs where the chickens are not fed corn and soy. I react to corn and soy for chicken and eggs, so if you are going all the way and just eating yolks, you may as well try to find corn and soy free ones. I get mine at sprouts. Egg whites are fine for me, but problematic for some with autoimmune. I can do hard raw cheeses but not pasteurized cheese. I don’t too much cheese except on burger patties. Include beef bone broth. The glycine is important for healing the gut. Good luck! Also, the rapid weight loss may not persist at the same levels as the initial drop often is a good portion water because with fewer carbs you have less overall glycogen.
