At a 170 lbs, I can’t eat over 2,500 calories a day without gaining weight- and I cycle 150-350 miles a week.

how many hours a day do you ride?

That's because your body knows it needs energy to sustain your biking.
When it sees a source, e.g. carbs, it stores them.

I have to roll up the windows when driving by a fast food place - just the smell makes me gain weight! I had to give up TV because the advertisements were making me fat, just by watching!

OK, maybe it isn’t quite that bad, but 40 years ago I lost 45 lbs, and I had to get down to 800 cal/day (while jogging daily) to do so.

Eat less/move more still works, but it works easier for some than others.

I’ve always thought it would be impossible to ride more than 100 miles a week without losing weight.

I’m very impressed.

Maybe you should weigh 195.
