make lots of skinny friends and hang out with them as much as possible. You’ll naturally adopt their habits, lifestyle, and mindset, and the weight will come off without even trying.

That might not work as well as you think. I’m (I was?) one of those skinny people who would eat a lot more than others when with friends and eating out, but on my own, I’ll hyperfocus and forget to eat entirely. It averages out to a pretty low Calorie intake. Neither of these are exactly good habits to pick up, and you’re likely only going to see the big meals when we hang out together. The mindset is just doing whatever you feel like doing. That’s the case for all of my skinny friends. I think it’s the muscular friends that you want to follow since they’re more intentional with everything.
