I've always been told that I don't need to lose weight by co-workers and friends. They always excused my weight with the fact that I'm tall.
So I've just learned to not take it personally. Someone commenting on how I don't need to lose is the equivalent to commenting on the weather.
My only response is "Just staying healthy!". That covers everything from exercise to nutrition to state of mind.
I would say the best way to handle this type of situation is all in your way of thinking. People are nosy by nature a little too often and it's all in our own control as to how much we let it bother us. GL!
I am at that really uncomfortable place where everyone I know is hyper-aware of my weight loss and watches me like a hawk, yet I have noticeably gained some of the lost weight back and am unhappy about it. I of course want to get rid of it all ASAP but feel like I am sneaking around trying to diet where no one can tell. Fortunately I am basically alone M-F and can do whatever I want, but on weekends I still feel like I have to pretend to be "normal" - whatever that means.
I guess it's complicated a little in that a good part of this weight gain is from binging that happens out of the public eye, but anyone who is anyone knows you can't just put on pounds that quickly without something else going on.
