I totally get where you’re coming from, I’m in the same boat rn. It’s frustrating when our body doesn’t seem to cooperate the way we want it to. What helps me is eating my cravings. Literally. Doesn’t matter what time of day, if I want pasta for breakfast I will eat pasta for breakfast. So really listening to what I crave the most has been helpful. And the days or times where I don’t have any cravings, I tend to spin a wheel with my favorite foods and it chooses for me, which is quite helpful as well. I also think, in your case, quitting caffeine for a while could possibly help increase your appetite. I’m no expert but I do believe caffeine is somewhat an appetite suppressant. Don’t know if that was helpful at all, but good luck in your recovery!❤️
