not to generalise, but i think when a guy says to a girl "oh you don't need to lose any weight" it's pretty much a knee-jerk reaction. if a girl says anything about her appearance that could be construed as negative, most guys will automatically say something positive - of course you don't need to lose weight, no your bum doesn't look big in that, etc. because they're all too aware of the almighty ****storm that will go down if they agree with the girl's negative comment about herself. bc let's be honest, a lot of girls are just saying this sort of **** to fish for compliments.
not saying that's why you're saying it, mrsrenske. but that's probably why your male friend automatically jumped in with "but you don't need to" type comments.
but yeah, i do find people are generally unsupportive when other people want to lose weight. i've pretty much given up discussing dieting with certain people because ALL they will say is "oh but you don't need to, you're not fat in the slightest!" errm yeah i never said i was?
