Morning appetite/night appetite switch, now with a skinny person gut?

Anyone else noticing that their appetite (what there is of it) is louder in the morning than in the evening now, ... if you (like me) pre-sema had a larger appetite in the evening and a more ignorable appetite in the morning?

I ask because it feels, anecdotally, like I've often observed the "naturally skinny" people in my life also report a higher appetite in the morning. Got a thought in my mind that the old advice to eat like a king in the morning, prince in the afternoon, etc, has some basis in antiquated fat-shaming and a blindness to the experiences of others.

Are skinny people just like this?? Does anyone agree re: morning appetite observations of themselves now/skinny people in their life?
