Stick to your diet even though everyone else isn't
One great thing about parties? The food, no duh. But what's a woman who hasn't eaten a carbohydrate since the '90s to serve at a function? Even she wouldn't subject people to eating wheatgrass and algae at a party where you're supposed to...ya know, let loose. So don't subject people to your insanely strict diet! Be sure to provide a smorgasbord of carbs and sweet eats for your guests, but don't you dare touch any. Instead, gorge on steamed vegetables, like Gwyneth did at her 2013 Hamptons soiree at chic eatery Serafina. Honestly, this isn't dumb on her part. This is extremely brilliant. Gathering the creme de la creme of blonde socialites with waif like figures to fatten them up so she ends up being the hottest of her crew. See, it turns out a University of Spoiled Children dropout is infinitely more genius than those "scientists" and "doctors."
