Eskimos in Stefansson's time), Stefansson returned to the Arctic with a colleague, Dr. Karsten Anderson, to carry out research for the American Museum of Natural History. They were supplied with every necessity, including a year's supply of 'civilised' food. They declined, electing instead to live off the land. In the end, the one-year project stretched to four years, during which time the two men ate only the meat they could kill and the fish they could catch in the Canadian Arctic. Neither of the two men suffered any adverse after-effects from their four-year experiment. Stefansson deduced, as had William Banting, that the body could function, remain healthy, vigorous, and slender if a diet in which as much food was eaten as the body required, with only carbohydrates restricted and the total number of calories ignored. While there was considerable skepticism when Stefansson reported his findings about the viability of an exclusively meat diet, his claims have been borne out in later studies and analyses. In multiple studies, it was shown that the Inuit diet was a unique ketogenic diet. While the Inuit diet derived a percentage of its calories from the glycogen found in the raw meats, the native Inuit ate a diet of primarily stewed (boiled) fresh fish and fatty meats such as caribou, whale, or seal, while occasionally eating raw fish. To combat erroneous conventional beliefs about diet, Stefansson and his fellow explorer Karsten Anderson agreed to undertake an official study to demonstrate that they could eat a 100% meat diet in a closely observed laboratory setting for the first several weeks. For the rest of an entire year, paid observers followed them to ensure dietary compliance. The book The Unseen Power: Public Relations states that Pendelton Dudley, once considered the "dean of public relations", convinced the American Meat Institute to fund this study. The results were published. Anderson had developed glycosuria during this time, which is normally associated with untreated diabetes. But unlike the pathology of diabetes, in this particular study, glycosuria was present in Anderson for four days and coincided only with the administration of a 100 gm of glucose for a tolerance test, and with the first three days of his pneumonia, where he received fluids and a diet rich in carbohydrate. Once that situation resolved, the glucosuria disappeared. At the researchers' request, Stefansson was asked to eat lean meat only for a time. Stefansson
