This poster presents the reason that Pacific Islanders are considered the most obese people in the world. It is not because they do not care about their bodies and therefore abusing their stomachs but it is biological, going back to the late 1700's when explorers considered them most healthiest people. During long voyages, the Islanders use to prepare themselves for famine, therefore it was passed on genetically to generations, indeed when the western influence around the World war II, the rate of obesity and diabetes began to show.
