Yup, I'd get the "too thin" comment after I lost all the weight... but it was from ppl who didn't know me years ago when I was at this weight, so they didn't know I have always been on the thin side. I realized it was a shock to them, they weren't used to me that way, plus, many ppl worry you will go too far, which is concern. Also, it's a way some ppl compliment, saying "you're thin!" It's like "wow, that "diet" worked!" My MIL would make a comment everytime she'd see me, but she's stopped now, she's realized this is the way I am now, get used to it!
