It's called portion control. But it's lost on many Americans. Just go into any chain restaurant, chain big-box store or convenience store and you'll see super-sized portions of food stuff just waiting to be wolfed down. In fact, we just posted a piece today about Jake's Wayback Burgers, an East Coast restaurant that has a 9-patty burger weighing in a 2,000 calories. No wonder 1 in 3 Americans is obese. The sad thing is that Americans waste 40 percent of their food annually.

If only restaurants in the United States would adopt the policy from this Japanese restaurant in Sapporo. Failure to consume a signature dish — a bowl of rice topped with all-you-can-eat salmon roe — results in a surcharge of 1,890 yen or about US $25.

The money is donated to the fishermen who made the food possible. A blogger posted the note from the restaurant's menu:

According to the explanation in the menu, the working conditions for fishermen are harsh and so dangerous that it's not unknown for lives to be lost. To show our gratitude and appreciation for the food they provide, it is forbidden to leave even one grain of rice in your bowl. Customers who do not finish their tsukko meshi must give a donation.
