Elevation

Set in the fictional Castle Rock, Maine, Elevation tells the story of Scott Carey, a man with a mysterious problem: no matter what he does, he continues to lose weight – and what only makes the condition more bizarre is that not even heavy clothes seem to impact the scales. And as though being a medical oddity weren’t enough, he finds himself embroiled in a controversy involving his next door neighbors, a lesbian couple trying to keep their restaurant in town afloat, but find their efforts impeded by bigots. Based on the 2019 novella by Stephen King

Unfortunately the movie Elevation is not yet available on HBO Max.
