Tbh the article you linked has one rather stupid take:

Even a quick glance at the weight research shows that, despite decades of trying, there is no evidence that efforts to prevent or reverse “obesity” are successful.

There haven't quite been any real efforts for decades, especially not in the USA. Banning ads for sweets and implementing a sugar tax should be very effective at reducing sugar intake, linked to obesity and those policies only started being implemented in recent years.

It's incredibly difficult to come by any research about those efforts because there's a multi-billion dollar lobby of advertisers and food manufacturers strongly opposed to this and any other policy attempting to reduce consumption.
