Here’s the forum diet that you sound interested in:
It sounds like you have a stomach acid problem and this is why you have gas and belching. This isn’t a good thing because your body is having trouble breaking down the foods you eat. Check out this post:
What meat are you eating other than fish and chicken?
I would only have yogurt if its goats yogurt, whole milk yogurt, or european yogurt. The cow should not be a black and white cow like we have in america but a brown cow like you have in europe.
If you are having diarrhea I would reduce antifungals.
