Today's Inuit, in the far north, as you know Teaser, are more likely to live in towns - especially during the winter - going out to hunt periodically - but mostly eating the food from the local store which is pretty high carb.

During the summer months, they go out on the land to hunt, fish and gather vegetation. I would assume that they would lose weight in the summer switching back to a purely low carb diet. Makes for a yo yo diet existence.

The doctoral dissertation of Dr Nancy Edgecombe may have more information for you. Since she is the nurse in charge of Inuit health, she might be able to answer your question. She is on facebook if you have access to that platform.
