Yeaah I'm definitely getting the sense that this is a classic "Jared from Subway" case of the Ring Fit being only a tiny portion of the equation for him. I mean, the game can kick your ass but not THAT much. Even going nuts on the highest difficulty and constantly engaging in action during those 25 minutes wouldn't make a huge difference. And you never know, the dude could easily just be sucking in the stomach a bit there.
I don't doubt that Ring Fit could definitely aid towards weight loss - as I've definitely felt sore and winded after just an hour or so of playing on the third difficulty level, and you're also working muscles with the resistance training which burns more calories over time. But even with all that considered, I'm sure this would have to be supplemented by proper diet, and probably even another means of working out, for it to really make an impact.
