I can't get a solid statistic on this, but didn't the obesity rate basically plateau last decade in countries like Italy, France and Germany?

My country (Poland) is an unfortunate leader in childhood obesity (and close to the top in terms of obesity in general), but it's very easy to see why: people live very different lives than they did just 20 years ago.
