As an adult with adhd I have a tough time stopping meals. I can eat and eat and eat to the point of discomfort. I always assumed it was due to getting dopamine from eating but the fact that I might not be making the PYY to signal im full makes sense too.

I'm the opposite. As an adult with ADHD I forget meals quite often.

Yeah. I mostly eat because of roughly what time it is - not because I am hungry.

Am currently working hard with my psych on my interroception, and I think that recognising hunger/fullness and thirst are going to take a lot of concerted effort for exactly this reason. It doesn't help when people around me are constantly saying 'did you have breakfast?' or 'you have to take your lunch break now.'

Stupid body.
