Ugh what to do in this situation?

" I'm NOT worried about how her friends will perceive me" - fixed. It's that easy. Project confidence.

Tell them you've been stuffing yourself all day and are not hungry. (If you don't mind stretching the truth.)

Eat before you go, have one slice of pizza or whatever while you're there and don't sweat over it (or make a big deal that you're not eating "those kinds of foods").

yeah, this.

I doubt anyone would notice.

If you don't want it simply eat before you go. When you get there tell them you ate. If they judge you it's really not your problem, it's theirs.

Just say you ate before you go, or you're lactose intolerant and if you don't want the beer, then you have a gluten sensitivity too.

Or don't worry about it. You choose to not like that type food and drink, all sorts of people both slim and fat hate particular foods. The bowling alley and bar don't have the foods you like, end of statement. Nothing about weight loss, or eating healthier, or even denying yourself.

Go and enjoy the company, and the bowling if you choose to bowl a game or two.

Try not to care what others think. They probably wont notice.
And if they do make an issue out of it?? They seriously need to grow up.

You could always just be honest if anyone says anything and say.. none of that sounds good to me right now. Aren't we supposed to be honest and stuff anyway? Makes life easier.

I say, "eat before I came" and then, maybe just have a beer with them so you can be a part of the social scene. But if you truly don't want the beer, for personal reasons, then just have a diet soda with them. Who cares what they think. Your choices are yours to make.

This comes up a lot for me, since many of my son's classmates have their birthday parties at the bowling alley here. Normally, I make sure to eat a healthy meal *right* before I go, so I'm not hungry when we arrive. When the pizza, chips, sweets and sodas are offered, I just say, "Oh, I'm good, thanks!" It's never offended anyone that I'm aware of, and the party goes right along as usual. If you act like it's no big deal, it won't be a big deal, nine times out of ten.

I agree with this...this is what I do as well...I eat before, when I get to the place, say "oh no thank you,...." and I try not to make a big deal about it. If they ask why for whatever reason, I'll say something like "had a big lunch" or "I was munching earlier and I think it ruined my appetite" or "...not right now, maybe in a bit, you guys go ahead..." . Because I am a little self-conscious about these kind of scenarios myself (not saying that anyone else is) sometimes I'll throw in a beer and babysit the whole night for the most part, just to have something in my hand and not make anyone feel uncomfortable.

"I ate right before I came"

Giggity.
