Well done on your weight loss OP.
I've lost weight many years ago and got called a bitch for it. Albeit from an acquaintance I doubt I'll ever see again.
I regained lost weight and am now back in a losing phase. I've collected a new diet and I'm back into the exercise. I don't care how many attempts it takes to do this. Never give up.
I've heard of people being dropped by good friends just because they have lost weight and are bewildered as to why their phone calls don't get returned. They are still the same person.
I don't think they realised the friendship was conditional on them being fat/significantly overweight. Maybe they were a marker somehow i.e. I'm not as fat as her. Do people have a fat friend just because they are fat ? Fat friend loses weight and creates a vacancy maybe ?
Sometimes you find out who your friends are when something goes wrong. Sometimes, believe it or not, you find out who your friends are when something goes right, or you have some success.
I once worked with someone who lost a significant amount of weight. I asked her on the quiet who acknowledges her now that used to look right through her. She named the office snob. I couldn't help but think, 'thought so.'
As a PP upthread remarked since losing weight she's in with the cool people now, at their invitation. Now her weight loss has qualified her as good enough for them.
Weight loss, unfortunately, is in the public domain i.e. Slimmer of the Year, diets and weight loss methods being advertised, t.v. shows regarding weight loss etc.
Therefore people think it's ok to talk to someone who has successfully and safely lost weight and they'll be only to glad to talk about it.
Success of any sort can give the person confidence. I suspect that's what other people really envy. Oh, and the fact you did not seek the permission of others before you lost weight.
I believe it happens to people who successfully give up smoking i.e. they get dropped by their friends who still smoke or struggle to give up. I understand people who give illicit drugs the swerve get ditched by their former drug taking friends. I guess they are no longer, 'one of us.'
