I've been trough that myself, my brother has done it EVERY day of my life, and is serious about it... my mother has also always been critical of my weight (she suffered from eating problems when she was around my age up until after she was married to my father even) some days I've taken notice of it and gotten really distressed, other days I just think, I am what I am, I do what I want...
since I turned vegetarian, the tables have turned... I HAVE lost SOME weight, but nothing that drastic, and they now say that I'm "fading away" especially my father... and they try to make me eat more, or try to get me back onto meat.. but in truth, I feel way more healthy than ever (and I DO get all my nutrients, I know how to eat sensibly)
so, after all of this.. there is loads of pressure, even from people who you wouldnt think would be so completely insensitive about it... and changing diets DOES change people's views... but if you arent well informed about what changes to make, it can lead you into trouble... its a fine line...
