Eskimo people have a mutation related to metabolism that prevents going to keto state when eating mostly meat. That alone can make proposed mechanism not working for them. Plus the persistent cold exposure may not be there due to warm clothes. For me more interesting is the story of cancer among aboriginal population of Australia. They do not use much clothes and at night there it can be rather cold.
