Your point absolutely has merit. I know some, but not many, badly overweight people who exercise regularly. I know some, but not many, skinny people who never lift a finger.

I was mostly trying to address the direct cause-and-effect conclusion the parent comment was making with breathing hard == losing weight

There's a lot of reverse causality in that relationship. Being badly overweight makes exercise more unpleasant and prone to cause injury.
