Yes, human nature hasn't changed but there is a reason why only recently obesity epidemic has developed.
Cheap unlimited access to stuff that was always scarce during human evolution creates an 'evolutionary mismatch' where unlimited access to stuff bypasses our lack of natural satiety mechanisms.
That is completely discounting the effects of PFAS and plasticizers on the human endocrine system and the downstream effects on obesity.
