As a naturally extremely skinny girl who has been in shidduchim for 2 years now, I can assure you that we do NOT have it easier in shidduchim. I was told at least twice that “many boys are not looking for a girl that is too skinny”.
I have never had eating problems and am very healthy. Many of my friends have gotten engaged and very few were a size 0-4.
So I don’t know if this is as widespread as you are all assuming it is. OTOH I assume that most girls who are engaged, are too busy to post on YWN, so that could make it harder to hear from the girls who were overweight and engaged.
Hatzlacha Rabba and remember, we each have our peckl in shidduchim… IYH we should all find the right one quickly in the right time and greet Moshiach together!
