Summary: This publication reviews the effects on the carbohydrate tolerance of two men after consuming a diet of only meat for 1 year.  Dr. Vilhjalmur Stefansson spent over 11 years in arctic exploration, during 9 years of which he lived almost exclusively on meat. Stimulated by this experience, Stefansson and Andersen, the latter a member of one of the expeditions, voluntarily agreed to eat nothing but meat for 1 year while they continued their usual activities in the temperate climate of New York.

Key Takeaways

After consuming an all meat diet for a long period of time, the body becomes unable to metabolize carbohydrates properly until they are reincorporated in the diet for a period of time. After two weeks of a general diet with carbohydrates, there will be no abnormalities in carbohydrate metabolism. This is physiologic insulin resistance, and insulin sensitivity will recover with the addition of carbohydrates to the diet.

Dietary strategies to increase endogenous ketone body availability such as the ketogenic diet (KD) have recently been shown to alleviate inflammation of the respiratory tract. However, the role

Weight loss peaks at about 5 months but is often not sustained. Individual weight change can vary from losing 30 kg to gaining 10 kg
