I spent a couple of years living in france and given how famous france is for pastry, cheese and rich food, i was genuinely surprised that there were very few obese people. French peoe are very active, but i put it down to fresh quality products, and paddock to plate approach to food. Sure, there is a lot of over processed food there, but if your buying bread for example, its always fresh baked. You buy cheese at your local markets, and fruit and veg also. Less preservatives and additives to make it all stay fresh.
