http://gamapserver.who.int/gho/interactive_charts/ncd/risk_factors/overweight/atlas.html That page says the % overweight or obese is 63% in Germany and 72% in the US. Can you ask her if that matches her observations? I'm skeptical of this data. It lists France as 67% even though they have a reputation for being thin. And I don't remember 65% of Icelanders being overweight or obese when I visited in 2008. I remember being surprised at the fact that I only saw like five overweight or obese people at most out of all the dozens of people I saw close-up. One of these fat people turned out to be a British person working in Iceland so these may not even have been Icelanders.
