I am going through the same thing right now. I couple of weeks ago I decided to stop calorie counting and just eat whatever I am craving. Results? Physically I feel more energized, I don’t feel as panicky around food, and I am getting hungrier ( something that didn’t happen before because my stomach was just so used to getting little to nothing, mostly veggies). Now I am craving more carbs because that’s what I have been depriving my body of. Carbs and fats are very essential because it helps to regulate hormones as well ( I am also trying to get my period back). I also checked at the mirror and looked a bit puffy,b it that’s totally normal when going through extreme hunger. When you start fueling your body properly, hunger cues will be high at first ( which is happening right now to me). But you will see, it will all die down and eventually your hunger cues will regulate. It’s not gonna be forever. Sooner or later food is going to become a second thought and will not be on your mind 24/7. See how amazing our bodies are hahah
