I don't think that proves anything one way or another. For example, it could mean that there are a smaller number of really obese people in America who are driving up the numbers. Therefore, there are fewer obese people in America when compared to Germany. Or it could be that your anecdote doesn't hold true. That someone who's visited Germany could say the exact same thing as you, that they always see people who are really obese.
