Are american women on average out of shape compared to Europeans?

So i am considering moving to the us for a masters degree. After I finish my masters I might stay there for 1 to 3 years due to stem opt extension.

I am 37, turning 38 soon. Dating is an important part of my life at the moment.

I live in Europe. I have never lived in the us. So all my experience is from reddit.

Sometimes i speak to american women on here. Most of the women who reach out to me are my age or older.

The thing I have noticed is 99 percent of the american women who contact me are severely out of shape. They look 10 to 15 years older than the age they mention.

I dont mind someone who wants to work on themselves. But there women seem yo think there is nothing wrong with being severely overweight and that they are "curvy".

Also almost all of them are single moms.

Compared this with europe, the women my age are in shape and look attractive. I still find some single moms but there are women with no kids as well.

I didnt know where else to post this question because posting anywhere else would immediately get me labeled as misogynistic.

I was wondering if this is the average shape of american women? Is this what I should expect when coming from europe ? Are things better in new york city etc ?
