Okinawa diet is a famous nutrient-rich whic is a low-calorie diet from the indigenous people of the Ryukyu Islands. In addition, a commercially promoted weight-loss diet (which bears the same name) has also been made based on this standard diet of the Islanders. People from the islands of Ryūkyū (of which Okinawa is the largest) are reported to have the longest life expectancy in the world. This has in part been attributed to the local diet, but also to other variables such as genetic factors, lifestyle, and environmental factors.
Generally, the traditional diet of the islanders is 20% lower in calories than the Japanese average and contains 300% of the green/yellow vegetables (particularly heavy on sweet potatoes). The Okinawan diet is low in fat and has only 25% of the sugar and 75% of the grains of the average Japanese dietary intake. The traditional diet also includes a relatively small amount of fish (less than half a serving per day) and somewhat more in the way of soy and other legumes (6% of total caloric intake). Almost no meat, eggs, or dairy products are consumed.
An Okinawan reaching 110 years of age has typically had a diet consistently averaging no more than one calorie per gram and has a BMI of 20.4.

The Ryukyu Islands, also known as the Nansei Islands (南西諸島 Nansei-shotō?, literally Southwest Islands), is a chain of islands in the western Pacific, on the eastern limit of the East China Sea and to the southwest of the island of Kyūshū in Japan. Since about 1829, they have been alternately called Luchu, Loo-choo, or Lewchew, from the Chinese name Liuqiu. They stretch southwest from the Japanese island of Kyūshū to within 120 kilometres (75 mi) of the island of Taiwan.
The islands are administratively divided into the Satsunan Islands to the north, belonging toKagoshima Prefecture, and Ryūkyū_Shotō to the south, belonging to Okinawa Prefecture, Japan.Yoron Island is the southernmost island of the Satsunan Islands, and Yonaguni is the southernmost of the Ryukyu Islands.) The largest of the islands is Okinawa Island.
The islands have a subtropical climate with warm winters and hot summers. Precipitation is very high, and is affected by the rainy season and typhoons.
The archipelago is home to the Ryukyuan languages. The original dialects are native to each island and distinct from one another.
