Their urine volumes were also high, a result of additional urea which the body uses to purge waste products from gluconeogenesis.However, actual evidence has shown that Inuit have a similar prevalence of coronary artery disease as non-Inuit populations and they have excessive mortality due to cerebrovascular strokes, with twice the risk to that of the North American population.Traditional Inuit diets derive approximately 50% of their calories from fat, 30-35% from protein and 15-20% of their calories from carbohydrates, largely in the form of glycogen from the raw meat they consumed.It has been suggested that because the fats of the Inuit's wild-caught game are largely monounsaturated and rich in omega-3 fatty acids, the diet does not pose the same health risks as a typical Western high-fat diet.Inuit studied in the 1970s were found to have abnormally large livers, presumably to assist in this process.This keeps their blood flowing and their bodies warm.They are no longer skilled in hunting like their ancestors and are growing more accustomed to the Qallunaat ("white people") food that they receive from the south.Because the climate of the Arctic is ill-suited for agriculture and lacks forageable plant matter for much of the year, the traditional Inuit diet is lower in carbohydrates and higher in fat and animal protein compared to the global average.Vitamin C is obtained through sources such as caribou liver, kelp, whale skin, and seal brain; because these foods are typically eaten raw or frozen, the vitamin C they contain, which would be destroyed by cooking, is instead preserved. Many hunters will eat the food that they hunt on location where they found it.Vitamins and minerals which are typically derived from plant sources are nonetheless present in most Inuit diets.There has been a decline of hunting partially due to the fact that young people lack the skills to survive off the land.

Inuit consume a diet of foods that are fished, hunted, and gathered locally.While postmortem glycogen levels are often depleted through the onset of rigor mortis, marine mammals have a much delayed onset of rigor mortis, even in warm conditions, presumably due to the high content of oxymyoglobin in the muscle that may permit aerobic metabolism to continue slowly for some time after the death of the animal.This high fat content provides valuable energy and prevents protein poisoning, which historically was sometimes a problem in late winter when game animals grew lean through winter starvation.The high costs of hunting equipment—snowmobiles, rifles, sleds, camping gear, gasoline, and oil—is also causing a decline in families who hunt for their meals.Not only have multiple researchers been unable to detect any evidence of ketosis resulting from the traditional Inuit Diet, but the ratios of fatty-acid to glucose were observed to be well below the generally accepted level of ketogenesis.
