I mean some people look unhealthfully slim like they would starve if there was too much snow or they couldn't leave their house for a protracted time.

Intermittent fasting has has nothing to do with being fat or skinny. My point about "skin and bones" is more about how normal it is to comment on someone that isn't overweight. I can't imagine people tolerating fat-shaming people in a friendly social context.
