I’m pretty sure that people who are super thin and fit don’t have any one weird trick, they just have been constantly exercising and counting calories and monitoring their weight for years or decades. There’s a fine line between being a health nut and having an eating disorder, especially in an environment where you are constantly surrounded by dirt cheap junk food. I mean I’m always, always dieting and running just to stay the same weight. It’s a red queen’s race. It's not all or nothing though- put in a moderate effort and you'll be rewarded by being moderately fit. And that's worth doing, for sure. You do feel a lot better when you’re thin and healthy. But there's no magic bullet. Don't beat yourself up for not looking like a movie star- those people spend an inordinate amount of time and effort being good looking, because that's their job. Also don't imagine it's easy. But it's definitely worth doing anyway, even just a little. You get moderate results for moderate effort, and that's ok.
