Walk Two Hours Per Bottle of Soju

Maybe this explains the amount of hikers in Korea:

Pocket books that identify exact calories and nutrients of 93 kinds of foods that Koreans eat most frequently will be distributed to people for free, the Ministry of Health and Welfare recently said.

The pocket books, aimed at preventing people from becoming fat by having a balanced diet, have been written following a nationwide survey on Koreans’ eating habits conducted in 2001. A total of 400,000 copies of the book will be given to people across the nation.

The pocket book provides information on the amount of exercise needed to consume calories gained from various types of foods. The book especially offers detailed information on nutrients and amounts of oil, sugar and salts used in various types of foods that are often served in an average Korean meal.

According to the health pocket book, a two-hour walk is recommended to burn off the 540 kcal gained by drinking one bottle of soju.

I would by no means consider Korea on the verge of becoming a fat society as this article seems to claim, but for the most part Koreans are avid hikers and will often drink the one bottle of soju while they are on their hike.  So as far as burning off soju calories I think the Koreans got that one well covered.
