Icebound Inuits consume no starches, which is one viable extreme. The other extreme is my method, which consumes minimal fat. Both are viable.

No they are not interchangeable. You can cut off all carbs (keto) but you can't cut off almost all fats. There's a limit on how low on fat you can get before getting malnutrition. Why? Because carbs are only used for energy while fats are essential building blocks for your body. You are not a plant. If you can't research the science behind that claim on your own there's no saving you. Sadly, one of the symptoms of fat starvation is brain function deterioration so you've entered a vicious cycle. Here's what your article says:

In Appian's Roman History, Volume I, Book VI: The Wars in Spain, Chapter IX, page 223, the author notes a multitude of Roman soldiers dying of severe diarrhea after eating mostly rabbits while besieging the city Intercatia in approx 150 B.C. Appian wrote:

... strange terror in the Roman camp. Their soldiers were sick from watching and want of sleep, and because of the unaccustomed food which the country afforded. They had no wine, no salt, no vinegar, no oil, but lived on wheat and barley, and quantities of venison and rabbits' flesh boiled without salt, which caused dysentery, from which many died.

They ate wheat (carbs) and lean meat (protein) but no fats and that made them sick.

A World War II-era Arctic survival booklet issued by the Flight Control Command of the United States Army Air Forces included this emphatic warning: "Because of the importance of fats, under no conditions limit yourself to a meat diet of rabbit just because they happen to be plentiful in the region where you are forced down. A continued diet of rabbit will produce rabbit starvation -- diarrhea will begin in about a week and if the diet is continued DEATH MAY RESULT."
