it's not that i like the whole “uwu-harry” trope or whatever, but you can acknowledge the fact that he's not exactly the tallest or sturdiest and still think of him as badass, master of death, one of most skilful aurors to ever live, etc. whichever headcanon people prefer. i've seen my share of people who have been starved, whether it was because of their abusive households leading them to be malnourished, or because they had an eating disorder. during the 90s, under the influence of international sanctions, there was a major economic crisis in my country and the emergence of hyperinflation. the said sanctions had a devastating effect on the economy of it and the period is remembered for the drastic drop in living standards and the shortage of basic foodstuffs, medicine and energy, and so my family (even my parents at a time), have often suffered from poverty and therefore hunger and let me tell you— yes. it most definitely can have lasting consequences on somebody. that's not to say that harry never ate or anything like that, (though he only ate properly during his hogwarts time during the time his body was just starting to develop) just that it's perfectly reasonable for him to be portrayed that way in the fan fictions. him wearing evident testament of his abusive childhood doesn't make him weak in any way.
i know there's people out there who often depict him that way in order to make him more submissive or whatever, but other than that, i really don't see the issue y'all have with him being shorter than he'd be in other circumstances.
