Alaskan Arctic Eskimo: responses to a customary high fat diet
by HoKang-Jey, MikkelsonBelma, LewisLena A., FeldmanSheldon A., TaylorC.Bruce
This 1972 study tested cholesterol levels and similar values of Alaskan Eskimos living in Point Hope, AK who lived a relatively traditional lifestyle. They had relatively high levels of cholesterol, but lower triglycerides than the average American population. Their levels of heart disease were about 1/10th as the general population of 1972.
None of them tested positive for urine ketones, but the authors report this would not be surprised, as the strips are not very sensitive. The Eskimos were also eating 30-35% protein, which is a very high number and would likely not lead them to be in deep ketosis.

Potential Bias of Doubly Labeled Water for Measuring Energy Expenditure Differences Between Diets Varying in Carbohydrate
by Kevin D.Hall, JuenGuo, Kong Y.Chen, Rudolph L.Leibel, Marc L.Reitman, MichaelRosenbaum, Steven R.Smith, EricRavussin
17 men were compared on a ketogenic diet (80% fat, 15% protein, 5% carbs) and "baseline" diet (50% carbs, 15% protein, 35% fat). The goal was to compare TEE as measured my metabolic chamber vs. doubly labeled water (DLW).
2 of the 17 had "incompatible" outlier data on DLW. Even after removing those, DLW on the ketogenic diet showed 126±62 kcal/d more TEE than metabolic chamber.

Hypercaloric low-carbohydrate high-fat diet protects against the development of nonalcoholic fatty liver disease in obese mice in contrast to isocaloric Western diet
by Anouk Charlot, Anthony Bringolf, Joris Mallard, Anne-Laure Charles, Nathalie Niederhoffer, Delphine Duteil, Allan F. Pagano, Bernard Geny, Joffrey Zoll
Mice were fattened up on a "Western Diet" (WD 16w; 58.6% fat, 14.4% protein and 27% carbohydrate) for 10 weeks, after which half were switched over to a low-carb, high-fat (LCHFD; 77% fat, 18.9% protein and 4.2% carbohydrates). The LCHFD mice continued eating more than the control group, yet lost weight. The LCHFD therefore isocalorically led to weight loss.
