Fat around the organs (visceral fat [0]) is indeed a problem. Though I believe you've got the causality wrong. Many fighting styles select for people with broad shoulders and narrow hips (sometimes known as the mesomorph body type, though that system has its own problems). Strict weight categories and, of course, lots of training keep them lean and any kind of fat to a minimum (ignoring heavy weight classes, some forms of wrestling, and meat mountains like Valuev).
If this isn't trolling (and I do suspect it is), it reads like fitness influencer tosh like "running kills gains, you don't want to a marathoner body".
