There was a post about the 170s, I think it was, being the Bermuda Triangle. Bermuda and Triangle as search terms might turn it into less of a needle in a haystack.
There are actually tons of threads about just that.
A great many of us started in the mid-200s (for me it was 237) and then hit a stall in the 170s or thereabouts. It's become a standing joke for many of us. I spent about 4-5 months in the 170s - every once in a while dipping into the 160s and then bouncing right back up.
I went from 250 to 172 - got stuck for about 6 months, then gained back 30. I panicked the next time I got into the 170s, fearing a plateau, but went right through it. Second time was the charm LOL.
I got stuck at 160 when I was losing weight a few years ago. It seems like a lot of people have a plateau around that weight. Good luck on finding the thread.
Oh wow. I missed that thread. And I'm here stuck in the low 170's and I've been in the 170's for months. Of course, I haven't eaten totally on plan all this time. so I can't call it a plateau.
