Cortisol is a stress hormone that cause weight gain. They tend to be less stressed due to working less and moving around, walking, etc more. So they aren't nearly as fat.

Cortisol hypothesis can’t be right. Cortisol by itself doesn’t cause weigh gain. You need energy (food) to create fat. Cortisol can lead to bad eating habits or cravings but can’t by itself cause weight gain.

For instance, look at Japan. They are way more overworked and stressed than we are. They are jumping off buildings in the middle of work. But I haven’t heard of any landwhales over there
