I was always model slim (up to the age of about 23). I travelled overseas to London a couple of times & eventually arrived home 20 pounds heavier at the age of 27, then I put on another 20 pounds, & then some more in recent years.
No matter how much I exercised & ate a low calorie diet, I couldn't nudge more than about 5 pounds off my frame. And most of this was before chronic pain & fatigue slowed me down.
I weigh nearly twice what I weighed when I was 20, but you know this "belly business".......
At the ripe old age of 56, I STILL get people getting up to give me a seat on a tram in Melbourne - as long as I've got sunglasses on

(to hide my eyes), because they think I'm pregnant (the eyes seem to be a dead giveaway to my actual age).
I say to the person offering, I'm happy to be standing, because I've got bad back pain, but every now & then, I wait for a
pregnant pause, and give a
pregnant smile 
& take the seat that's offered.
Ya gotta love that offer, when you're 56!.
My Doc says I should be flattered that people think I look young enough & COULD be pregnant.
Sometimes I think........maybe they think......... that I'm old (you know the greyish hair bit). But actually my hair looks like it's been highlighted that way.
Or maybe they think I look exhausted & if I don't get a seat on public transport soon, I will faint or expire completely (& in the past, I HAVE come close to fainting & actually had to get off the tram because of wafting strong perfume etc playing on my MCS).
All I can say is...................
"Well men, if you ain't got a butt for me to pinch, ya gotta give me a belly to lean against when I feel faint."
