There is someone in my life who I don't see very often, but every time I see her she makes comments about her weight. I can tell that she feels really bad about it because she talks about it A LOT-- in a way that she is jokingly making fun of herself. Since she is overweight (but she is trying to lose weight), I think it would be so fake to just say oh you're not fat, or something like that. But I don't know what to say. I feel like she takes it as an insult if I laugh awkwardly at her self-depreciating jokes, but I just really don't know what to say (because many times anything you say concerning weight can be taken as an insult). What can you say in this situation?
