some people call it "starvation mode" and it's also related to "set points". The scientific term is adaptive thermogenesis. Sometimes starvation mode refers to something else entirely, but otherwise, I think they all more or less refer to the same thing. Giving it more names just adds to the confusion! (As far as I can tell, it's not particularly well understood anyway)
