I also try to avoid the topic now. I know the comments... "oh, you should try the ...... diet, I heard it really works". The answer that runs through my head is "I've lost 30kg. I think I'm doing pretty good with what I'm doing now, don't you?", but I usually just say "No, I'll just stick with what I'm doing" or similar.
I guess in a situation where people are discussing your weightloss I would be tempted to say "yes, I AM doing really well aren't I? If you would like some tips on anything you're wanting to change I could give you some really good motivational advice, like say auntie jenny, you know how you always have one too many drink?? well, you might want to just start setting yourself goals, like I did. Just one less glass of wine a week and before you know it you won't have to take this brochure for AA!"
My bet is most people who do this are just looking for something to talk about. Start aiming the topic at them and watch it change. I say this now, but I don't think I'd be quick witted enough to come up with it on the spot, and depending on the people, probably not rude enough ether (I am trying to contain myself these days).
35kg lost. (November 2005 - October 2006)
15kg gained again (as at October 2010).
Back to the drawing board - Let's do this thing!
