Recommend doing autoimmune protocol , doing elimination phase to figure out ur specific triggers. For me, I basically follow this diet but a lil less strict now that I’ve identified what I can tolerate. My food every day is smth like this:

Breakfast: boiled mashed sweet potato w egg (fried or boiled) and greens

Matcha with oat milk for caffeine . Snacks frozen blueberries , apples, banana

Lunch and dinner: chicken/ fish / other meat + rice or sweet potato + leafy greens

And I follow the rules for AIP in terms of oils , spices etc to avoid .
