Anecdotally, to me it seems like my metabolism hasn't changed. I was overweight when I was younger because I overate. Now I don't, and my weight is normal, on the low end for my height. But nothing about the quantities turning into pounds changed, from my p.o.v. (mid 40s now).

Actually the main thing that changed for me is I started compressing all my eating into 1-2 meals per day. That way I could track it. Before I couldn't tell you if "I haven't changed my diet" because it was a continuum of eating from morning till night. I have no idea what changed over time, couldn't even tell you for one week. Once I "bounded" it I was able to bring my weight down quickly.

Btw, sorry if this sounds snarky, it seemed like flagging this as anecdotal was the right way to start so I copied it.
