Why French kids are mostly not overweight

This is just my guess, but here are a few reasons I think French kids, and possibly French people are generally not overweight, and this is generally true for most of Europe:

- While the food is rich, the quantity is little and reasonable, not only in restaurants, but also at home, at the dinner table - they don't have a need to have a meal that can feed a Catholic family served to one person
- They walk and bike a lot more
- There aren't nearly as many commercials for junk food, and when they're on, at least in France, they put scrolling text under the commercial that says "for good health, avoid eating junk food between meals" - ah, the magic of POSITIVE subliminal messages
- Pop and most sugary drinks are expensive - OK, I hate this a little bit, but then again, they can't make regular Coke expensive and diet Coke cheaper, or can they?
- Kids, well, at least my little French cousins, are good, and when their parents aren't at home, they don't raid the cabinet that has the cookies adn chocolate in it, but this has more to do with the parenting than the nationality
- It probably helps that fruits and vegetables actually have a real taste here, and are not completely grown in green houses with a lot of chemicals, which makes them more appealing to children - I have witnessed a child actually picking strawberries for dessert over cake - un-freaking-believable!
