Obesity vs overweight (the former is surely a better predictor of health outcomes anyway) aside, we’re definitely higher than comparable nations, but I wouldn’t say significantly so.
Even the link you provided says that the US would fit among the Arab countries, but would be a major outlier in Europe. There are people with bellies here, BMI > 30, but the "unable to walk without a motorized wheelchair" category is rare.
I live in the Czech Republic, a notorious beer-guzzling nation that was never known for being slim. But the kind of obscene, ballooning fatness that is ubiquitous in the US was never seen here until, say, 2015. Unfortunately I slowly see it slowly emerging among the youth, probably the ones who live on the fastfood diet.
(Fast food used to be relatively expensive compared to Czech salaries, so people wouldn't gorge on it everyday, but this has changed and now it one of the cheaper options out there.)
Having said all that, I happen to know there's a school of thought that many (if not most) of the health issues supposedly "caused" by being overweight are largely an artifact of health professionals being so focused on their patients' weight that they fail to diagnose other health issues early on, or that patients no longer feel comfortable speaking to their doctors etc. The fact that the stats on diabetes/stroke/heart failure etc. correlate so strongly with obesity across such a large range of countries, even those where apparently "fat shaming" isn't a thing, leads me to be somewhat skeptical of that POV.
