How Other Countries Are Fighting Obesity

Obesity has become a worldwide epidemic. In Japan, they are measuring the waistlines of people 40 and older. Those considered too fat are ordered to undergo diet counseling. Failure to slim down results in fines. New Zealand has rules barring people who are too fat from immigrating to their country. In Great Britain, where 50% of the population is overweight, residents in some cities are being recruited to wear an electronic tracking device to calculate how much they move each day and how many calories they burn. Those that exercise daily are rewarded with store coupons and days off from work.
What do you think? Is the U.S. doing enough to fight obesity?
A FOOTNOTE:
I spoke with someone from Japan who is following my blog. He said:
Surely, Japanese government made a standard about waistline for citizens. But it's not compulsion and no penalty. All of Japanese can take a diagnosis at 40 years old free. I think that purpose is reduction of adult diseases. Therefore,almost all the Japanese think that is healthy standard.
