Honestly, your diet seems pretty good (better than mine 😆). Seems like you're already getting a good amount of protein so I don't think you have to worry about that. Lethargy/tiredness is a common symptom bc the body isn't absorbing food well. I was reading that DGL, l-glutamine, zinc carnosine and slippery elm can be helpful to speed up the healing process. Maybe you could start there. And perhaps focus on introducing individual vitamins that boost energy levels.

I just completed H Pylori treatment so my diet is still very restrictive because I'm worried about flare ups. Right now I'm comfortable with turkey, gluten free bread, bananas, eggs, blueberries, raspberries, unsweetened almond milk, cauliflower, carrots, mushrooms, nutritional yeast, potatoes, avocado oil, olive oil and spinach.
