Ironically, he'd look ten times better if he did the opposite of what he's doing now (living on carbs and sugar) and switched to the keto diet which is mostly proteins and fats. It'd get rid of the chub while making him look slightly more muscular/cut because unlike with most diets, keto really helps prevent the loss of muscle mass that often comes with weight loss. It's the perfect lazy-man's diet as the weight just falls right off but you don't look gaunt or weakened even if you don't work out.
But Gurg would never do this, because that would mean sacrificing woke vegetarian internet points AND admitting he was wrong AND adjusting his behavior accordingly, AKA three things Greg is entirely incapable of doing.
(Not saying vegetarianism is wrong, just that his version of it is, and if he's going to be a lazy fuck with food, he might as well be one in a way that helps him look better, especially if he's going to insist on pursuing this porn "career.")
The spiderman suit freaks me out. Makes me think of those creepy pedo-baiting youtube channels "for kids" that would show Spiderman getting Elsa pregnant or whatever else degenerate shit to groom children. If I'm not mistaken, these videos played a huge part in the original YT adpocalypse. Using a character kids love to do your porn is just gross.
