Help me retort politely

[squishee]

when a fellow diner at a buffet says

"You eat a lot, don't you?"
"You put it away"

and suchlike.

This has happened to me twice now. Both times I was too taken aback to reply properly and laughed it off.

Yes I do have significant food hang-ups, which come to the surface in all-you-can-eat situations. I guess some might call it disordered eating. Hence I've posted on this particular board.

TIA!

If you're a healthy weight, maybe something like, "Yes, apparently I born with a fast metabolism."

If you're not, you could just dismissively, "Mm hmm." Then continue moving around as if they didn't say anything. Or, "Yep, sure do, " neutrally, then just keeping moving.

What I'd really like to say is, "And..?" or "Why do you care?"

Just breeze past it as the uninteresting/silly/offhand comment that it is - just a "uh huh" or a "sure do". I hate people commenting on anyone's eating habits or size.

Hate buffets and this is one of the reasons! I ignore, they’re just random people being rude, any retort, for me, is more hassle for me, and unlikely to lead to them reflecting on their rudeness or changing their behaviour.

Yes, apparently I born with a fast metabolism

I've said variations of this before, I am.a.healthy weight but can really eat on.occasion and it has been commented on. I also say that I don't eat like this everyday and I exercise a lot as.well
I hate it because it makes.me feel defensive but I also.know that the person commenting is rude so I brush it off and move on

I’d go with ‘yup I love a buffet’ then move off

Thank you for your replies.
I wish I could have pulled back from the situation and said something clinical ike "Did you just comment on my food intake?" But in the moment, with a hangup and a degree of social anxiety at play too, I didn't have that kind of repartee.

Just say ‘yes’

I’d be inclined to ask them to repeat what they said, this usually makes them uncomfortable, or I’d say quietly that each time someone says this to you it triggers shame and upsets you then just pause indefinitely. They won’t do it again!
