Hockey fandom has gone through a couple of phases on this. You don't see egg white omelettes and diet food like you used to, now that people better understand calorie requirements, but you still get the obnoxious self-shaming and "indulging." I get that it's people/women putting their own cultural programming onto their characters, plus it's just something to talk about in a fic besides "they ate a huge pile of chicken and pasta for dinner," but it's a lazy go-to for a lot of long-time writers (there was a recent offender) that's both inaccurate (dudes just eat junk or they don't IME, they don't angst about it) and also drags in all this stuff I don't want to see.
