I hate to sound mean but......

I would say do nothing. People are going to do what they want to do. If someone suggested to me to change my eating habits before I was ready to, I would not have listened and I would have been very pissed off. It is up to her to change, not up to you to change her. At one point, people would have looked at my food choices and been repulsed as well. Thankfully no one said anything. People have to want to change.

^this. maybe having a job is very important for her/her family, so she might not decide to change her eating habits until she's less stressed. For a lot of people, junk food is a vice. Either way it's unhealthy, but either way most people have unhealthy emotional or tangible vices that are unhealthy to cope with their responsibilities and stresses.

Can't help them that don't want to help themselves

I personally would bring an extra snack or something and offer it to her. and do that once every so often maybe she find something through you that she ends up liking.

Is there no way to put it a polite way? Hmmmm... it's a thinker.

At the same time, what would be the difference of someone eating at a very unhealthy rate, and who is at an unhealthy weight range, and then someone standing on the side of a building ready to jump?

Would all those people who said "leave them be it's their problem, etc".. say the same thing to the possible jumper on the side of the building?

I think if there were a jumper on the side of my building I would pray that there was a "professional" on the scene to talk to them, as saying the wrong thing can have the opposite effect as what you are hoping for. Which is the same for what the co-worker is talking about. Her words could have the opposite impact of what she's hoping for. That's how the situations are the same. How they are different is the jumper scenario has an immediate risk of fatality - so if I were the only option (and I would hope I wasn't), I would do my best to keep the person on that ledge for as long as was necessary to get them off that ledge in the right way. But at no point would I find the jumper's behavior "repulsive" or some other judgemental term while claiming to "only want to help them".

To the OP.. there are a lot of sheeple in the world.. it is expected to get responses such as some of the ones you have received. I have no doubt you'd like to help your coworker, I would want to do the same. It's just the question is, how to put it across.. like my prior post on here, would you let someone on the edge of a building jump? No.. so why is this any different?

I would deck you just to give an idea of what she might do. I wouldn't just be humiliated that your watching me like that but then you put me on the spot. She will have her breaking point one day and she will lose it and if she doesn't want to it's not up to you to tell her to.

WOW op's getting a hard time here when all she wants to do is help a co-worker. Normally i have all the tact and diplomacy of a sledge hammer so i can empathise with your situation. If you really want to say something why not tell her about your own 8lb loss and how it was so easy to do using MFP. If she decides to look at the site then she may change, if she doesn't then at least you can say you tried. Just make sure you are telling her about your achievement and not telling her to change.

What bothers you exactly? Watching her behavior? Hearing her eat? Smelling the food? Knowing she's eating what you want to eat?

I think figuring out precisely what bothers you would be a good start. You are the one being bothered, apparently not her.

For me, I think hearing package rattling and the smell would get to me. I'm guessing it is typical in your office to eat at your desk, so I don't think it's realistic to ask her to stop eating at her desk. But if it is, then ask HR to help out. You don't need to enforce the office rules.

Depending on the work relationship, and understanding what exactly bugs you, you could talk to her about your own weight loss and struggles to keep your goals. Ask nicely if she would please help you out by putting her food in a bowl so you don't hear the package noise or not throw food garbage in the cubical trash so you don't smell it, or whatever. I believe a friendly approach gets better results, and she might be more supportive of helping you out than you think.

Why would you post something about your overweight coworker when you are overweight yourself? Concentrate on your own weight. You don't have a clue if she has medical problems, nor have you walked a day in her shoes. Your post comes off as very mean spirited.

Yes I do know that she has medical issues because she has said something to me about it before. And Im not trying to be mean at all!!!

I guess If I ever see her ready to jump of a bridge I should just mind my business then too.

Maybe Ill send some flowers to the funeral and let the family know I let it happen.

You people wouldbe surprised on what the smallest amount of impact can make on a person!

Good Day People!

Ask yourself: "if my coworker saw my original post in this thread, would her feelings be hurt?" I'd be willing to bet it's a resounding YES!!!! That does make it kind of mean...

I disagree. Asking a internet fitness community what they would do when faced with a situation of a co-worker literally eating themselves into sickness doesn't seem mean to me. Though many of the replies have certainly been mean.

Also,

I simply asked what you guys would do. And guess what you all did STARTED JUDGING ME!!! hahahahahaha. Im sure you all know what that makes you all!

You really learned nothing from the responses you got didn't you? Other than that you should close your food diary lest someone see what a hypocrite you are?

If you honestly can't see the irony in saying you're not judgmental and then immediately calling someone "repulsive", then I don't think anyone is going to be able to explain it to you.
