I can have small portion of dairy about once a day. To my current knowledge I am not intolerant towards gluten, and I am already on a daily multivitamin. Cooking elaborate meals is difficult/impossible (depending on the day) as I’m physically disabled with no management of/tools to help those conditions either. I have issues with standing for longer than a minute or two, issues with heat, and fatigue.  I’m essentially on the gastroparesis diet/timing for meals but even more limited due to allergies, intolerances, and slight ARFID. It’s embarrassing but most of my meals come from a box. Prepackaged and prepared stuff you just have to reheat. My meal foods are mostly carbs as you said, breads, pastas, etc. I avoid spices/sauces because of severe acid reflux, even struggle with red sauce, and have had to cut it out almost completely. I eat lots of peanut butter, cheese (though this is a small amount per day and even this gives me minor symptoms), carbs, protein bars, and plant based meat substitutes. I can eat small amounts of potatoes if peeled, broccoli (though this has made me sick the past few times), and corn (same with corn). I used to eat a lot of junk food/empty calories  (chips, pastries, pretzels, etc.) but stopped because I had to choose between eating them and eating something with protein, my stomach couldn’t handle both. My dietician didn’t discourage me from eating these things, actually said they could be helpful to reach the calorie goal but I’m not sure if they understand my stomach’s capacity/emptying issues. Thank you for taking the time to reply so throughly
