Need breakfast ideas that are gluten and dairy free

Most noticeable thing from what you said is that you feel fuller with protein whereas cereal and fruit definitely lacks a good amount. Smoothie is my go to- collagen peptides for protein, add fat (hemp seed oil, coconut, or macadamia nut oil), frozen fruit, add fiber (no blood sugar crash). If I need more carbs I’ll blend in some overnight oats. That stabilizes me and is easier than deciding what to eat. I mix up the fruit and oil variation to get more variety so I don’t get tired of it.

Oatmeal or Cream of Rice cereal?

So, there’s lots of reasons you could still feel hungry even after eating. One thing that for some reason a lot of people don’t know: you might not be hungry. You could instead be dehydrated. So drink a large glass of water and see if you’re still hungry after that. Also if you have low blood sugar or for whatever reason there’s a drop in your blood sugar, even after eating a big meal you might feel hungry. To combat that, you just need to eat foods higher in protein, fiber & fat. Oatmeal, bean burritos, or lots of fruits and vegetables can solve that issue. Avocado too.
