... Also what do people say/think of you when they see your belly. ...
I'll admit I don't go to such places, but perhaps I can offer some insight.
I remember one time, back when I was a teenager, this friend of a friend, I saw her wearing shorts and a top that showed off her midriff. She was also plump and overweight. My father in confidence said he thought she didn't have the body for it, but he would never say so in public.
Of course, I thought she
did, and I thought she was pretty cute, but I'm an FA who wants you to overeat, so of course I'm gonna say that. Sadly, back then I didn't yet want to admit to myself that I love heavier women who can really eat. Sometimes I wonder what it would have been like if I asked her out on a date, maybe eat lots of pizza. Last I heard, she got married after college. Lucky man. He gets to enjoy her every day and watch her swell up from pregnancy, marriage weight gain, and eventually, the middle age spread will kick in.
I should also mention this was around a couple of decades ago. The U.S. has become considerably heavier and thicker since then. It's actually getting to the point that you'll stick out if you're really thin.
You would have to be very heavy to really stick out, nowadays.
I suppose some folks may privately be disgusted, but I get the impression this is less and less relevant, as America gets fatter every year. In fact, if current trends continue, the U.S. will reach majority obesity (BMI 30+) in '30 and continue to rise.
