Stage 2 is meant for later in your treatment, stage 1 is meant for earlier in your treatment. I would look at your picky food problem as one of the reasons you are here in the first place and you’ve gotta change your mental outlook on it. I am also a picky eater and my picky eater problems created nothing but troubles for my recovery.
The reason you aren’t recovering as well as you’d like is because your diet isn’t strict enough. Stage 2 is meant for later in your treatment when you are mostly symptom free. I started stage 2 after 9 months on the diet when my leaky gut healed.
You need to eat lots of veggies on the diet. Low servings of meat, and tons of prebiotics/probiotics. No rice, no molds, no fruits, etc.
What supplements are you taking as well?
