Because we've actually read the research, understand what it means for people like us, and we're done pretending we can just avoid regaining like we always have before, if we simply believe hard enough that 'this time will stick.' No, realistically it wouldn't. If doing this without medication were possible for me, I'd have already made it happen. Wanting this desperately my entire life and never once managing to hold onto it, even as a teenage girl in the late nineties who could recite the calorie count of literally everything I ate, never taught me how to stop the compulsion to overeat too often. Gritting through stretches where I resisted only taught me one thing: eventually I'd always run out of mental energy to keep fighting it.
My BMI sits comfortably in the normal range now, genuinely fit. This is something I've chased my entire life, and reality lives up to what I always pictured it would feel like. Won't gamble with losing that, and if holding onto it means staying on the medication forever and keeping a stocked freezer as backup against losing access, fine by me. I'd have made almost any sacrifice for a body like this, and a weekly shot that keeps me sanely balanced honestly feels like a small price
