Epigenetics does play a role in a way medications are starting to be able to address (basically there’s extra little hormones and stuff your DNA makes when recent generations have been stressed, so if the great depression hit your great grandma particularly hard your genes might still think you need to hang onto some extra fluff just in case). But yeah a lot of it is social stuff that just isn’t going anywhere like McDonald’s being the only place you can get calories at after job #1 and still be on time for job #2.
The crazy thing is is that epigenetics plays such a massive role that even a single generation of intentional change can produce astronomical differences, like when you see a third-generation Mexican immigrant who is like six foot five, and they go and hug their four foot four grandmother.
That early childhood supply of abundant calories in an active environment with low stressors can make such a huge difference on how your kids end up looking and how their entire lives play out, and those changes will likely propagate down through the generations.
