Negativity...

Kill her with kindness. I deal with it every day. "eeeewwww abs are for men" "you're too toned"... blah blah.

Smile and say "thanks for your opinion but I am happy and healthy and that's really none of anyone business.

My husband has had to deal with that too. My mother specifically bugged him about being too thin, and he told her, "Actually, I'm not. My BMI is 21, and underweight is 18.5." Plus, he's been doing stuff like P90X and Insanity wanting to build muscle, so I haven't been worried about him - because he's doing it smartly.

I'm pretty lucky in that the people I work with are all on board, and have all gotten fitbits. Once in a while, we'll bring in stuff we shouldn't ought to, but it's not often, and we don't lay it on people's desks - we put it in the kitchen.

Someone once asked me how much I wanted to lose - I told them I wanted to get down to about 145. He said, "There'll be nothing left of you!" I told him, "That's the plan!!"

If the co-worker keeps bringing you crap to eat - tell her it isn't "food journal friendly," and that you're afraid if you eat that stuff you'll end up looking like her. LOL

Actually she looks really good is thin.

She probably doesn't want you to be thin and look better than her.

I would just turn it around and make her answer the questions. I'd say "what are you basing your opinion on?" Or "why do you feel that way?" Whatever the answer is you can just say "Well, thanks for sharing that with me but I disagree". I had someone try to pressure me to drink soda when I didn't want it. After saying no several times I just stared at him ...blink...blink...to put the attention back on him and make him realize what he was doing. After a while he got embarrassed and stopped. If it went further than that I'd say "why do you want me to eat/drink that so much when you know I don't want to?" When people are pushy I push back. Create your own boundaries.

Lol, co-workers! sabotage!

My stepdaughter made this comment the other night "Talk about yourself, not me" kinda catchy I think : )

Anyway, I work with a bunch of men and they are busy lifting things and going up and down stairs while I sit at a desk all day. When they want fast food and they ask me if I want some I usually turn them down. Then they say "that's right, you don't eat that stuff" and I say "oh...trust me....I eat, I just really have to be careful". That usually works.

ETA - By the way, I am 5'3 and weigh about 129 looking to lose 4 more lbs. and about 2% more BF. It's tough to be short!

Wow.. she sounds super jealous. I work at a physio office and all of my co-workers are very supportive. Especially the day girl, who herself lost 80 lbs! However, at home, I face challenges because my mom is very unsupportive. Mostly, I try to explain to her that I'm doing this for myself and I don't feel comfortable with my body yet. When I reach my goal, I will stop. You have to either sit down and talk to this person one-on-one or.. report it to a manager because I would argue that this type of behaviour is considered workplace harassment!
On a side, note, congratulations on your success! You look fantastic. We are about the same height and started at roughly the same place - my goal weight is even the same as yours! I only hope I am as successful as you. Keep rocking it, girl - you're doing amazing. Don't let anyone stop you now. We don't stop when we get to the finish line - that's when we give it even more than we started with!
