Lt. Frederick Schwatka - Franklin Expedition
In 1879, he made "the longest sledge journey by white men; eleven months and four days and 4,360 km. That was the first Arctic expedition on which the whites relied entirely on the same diet as the Inuit. They ate only the animals they slaughtered. They were in ketosis all the time.
Lt. Frederick Schwatka, wrote about this diet, and how strong and healthy they were. They could work with heavy sleds and dog teams, all day, every day. They lived and worked on a carbohydrate free, and vegetable free diet. He was largely ignored in the USA.
Schwatka received the Roquette Arctic Medal from the Geographical Society of Paris, and a medal from the Imperial Geographical Society of Russia.
