So here’s the thing about long-term, sustainable weight loss: it’s not real. The statistics are extremely clear that virtually everyone who deliberately loses weight gains it back (and sometimes more) within a few years. And cycling between weights (as commonly happens when people try to lose weight) is really bad for your body. Pretty much the only way to lose weight and keep it off is to develop an eating disorder or weight loss surgery, which are also really bad for your body.
On the other hand, your boobs, once removed, will probably not grow back. Long-term sustainable boob loss is possible.
It’s not fun being fat. We live in a society that places a high value on thinness and equates being fat with laziness, poor health, and immorality. But there’s also no way out of it that doesn’t severely damage your body. I’d love to be thin again, but I also don’t want to sacrifice my health for the sake of looking healthy.
(As a footnote I want to add that there’s nothing wrong with being fat and that our desire to be thin is a cultural imposition that is not universal, but I’m also not convinced that the desire to transition isn’t at least in part the result of cultural impositions regarding ideas of sex and gender, so it’d be hypocritical of me to say that the desire to transition is innate/biological while the desire to lose weight isn’t.)
