Obesity is not evenly distributed by age or demographic. If you're a relatively young person in the workforce, you probably don't know such people. But it is true that obesity is much less prevalent in most of Europe. Even the places with less "healthy" diets, suprisingly.
But obesity rates are going up there, too, they are just lagging behind the Anglo world.

Let's put this into perspective. On average, the US has about twice the obesity rate as Europe (though in both cases there is a fairly wide variation regionally). And Europe has 4 or 5 times the obesity rate of Japan. So relatively speaking, Europe is not in a position to argue that their regulations or lifestyles are the answer.
