An eating disordered mind likes to fixate on other people's set point, and set point in general, and "why is there obesity?" They're all potential "this can't possibly work for me" loopholes that could justify continued restriction. How people get to whatever weight they are (which I now recognize as not my business) is likely a combination of genetics, environment, dieting history, mindset, stress management, all kinds of factors, and it continues to evolve. It's never static. There is no trap that you might fall into, no lightening bolt where a set point is permanently bestowed upon you and then you're either screwed or lucky. How you treat yourself is always what matters most in terms of health and happiness. When we treat ourselves like crap, we feel like crap, and then (surprise) we often turn to our go-to thing, whether it's restriction, overexercise, or numbing out with food, in an attempt to feel better. That can definitely influence a person's weight. It's not just a matter of luck or biology. It's not which recovery method, influencer, or study is right or wrong. How we treat ourselves is everything.
