I'm sick of this crap about other countries' eating habits. They always fail to mention that the average person in those countries [at least until very recently] got ALOT of physical activity on a daily basis. As things are now, most americans can never hope to reach the level of physical activity most of the Hi-Carb countries do [or did until recently - physical activity is decreasing and obesity is increasing in Europe and Asia.]

Americans have jobs which require them to come in early in the morning and sit all day...We don't get exercise breaks like a certain Asian country. We don't walk alot and depend on Public Transit, like some European countries [since gas here isn't $4-5/gallon yet.] Our schools are cutting back on recess. Parents are leaving their kids in aftercare [because both parents work 9-5] where in some cases they do sedentary activities, nap, and eat sugary food...not like it used to be where we played on the playground for those 4 hours. Short of somethign catastrophic (like a terrorist setting off an E-Bomb in a major city) Americans are not going to ever again achieve the level of physical activity needed to counteract the negative effects of a Hi-Carb diet.
