It’s the suburban mom (or dad sometimes) who wants help losing a little weight. Instead of being 300lbs like your example, she’s 160lbs and wants to be 140lbs.
I do want to get back into biking though. Haven’t ridden in a long time.
Those that still want to reduce their weight: All of them are on GLP-1s now (and losing weight!)
Those that had totally given up: They had long since stopped attempting anything to reduce their weight
I suspect that the larger you are, the more likely you are to fall into that second category - getting to 300+ lb involves a certain level of accepting defeat to begin with.
