France is going shit in this regard as do most developed countries, that's true, but my friend if you want to equate US and FR when it comes to diet and results on current population, they are not in the same league, heck its a different universe. French are much more conscious about quality of the food, fine taste and other aspects that cheap junk food doesn't provide. Walk around any french town, you will see crowds of tall, slender thin people with few overweight folks. Sports are a priority and source of pride, alpinism, climbing or paragliding are deemed as national sports, not some extreme fringe stuff for few adrenaline junkies. Do the same exercise randomly in US, and chances are very good what you will see will be dramatically different. That being said, there are (were at least in 2003) many faces of US - I've spent that summer working blue collar jobs in US as part of work&travel programme US was providing, and already LA was exactly as we discuss. Then I moved to rural Maine and it was night & day, I've met maybe 5 fat people in 5 weeks spent there (but its true racial diversity back there was 0, I've seen 1 black guy in 5 weeks and maybe 2-3 of asian origin, rest looked just like they arrived from Scandinavia). But judging by various articles and feedback from friends that Maine experience was much less common than LA one, and over time even more so. US portions are simply needlessly big and often unhealthy. The logic is to eat till full, instead of just warding off hunger and enjoying few very finely tasting bites.
