Food is different for me. When I first got diagnosed and medicated for ADHD I realised that I was ALWAYS hungry. Like always. I had never not been hungry in my life. I had been full/stuffed but hunger just does not work properly for me. Meds just suddenly made me recognise it. So I can eat my breakfast and not be craving food in ten minutes again.
Not a doctor but I reckon what I had thought was hunger was actually craving dopamine. So I was eating because I thought I was hungry and looking for the kick of sugary foods but I really just needed balanced dopamine levels
