Hi Jim,
Thanks for bringing that up. V.Stefansson wrote about the Inuit feeding 
lean meat to the dogs while consuming the fatty cuts and fatty organs. 
Talk to anyone who has worked/lived outside in very cold weather for 
extended periods. They will tell you that you need fats to stay warm, 
not carbs. Rabbit starvation was taught when I was in school, as some 
pioneers succumbed to it in the Peace River area of northern BC and 
Alberta, and they were sometimes limited to only rabbit meat due to 
weather conditions. We must eat some carbohydrates or fats for energy 
and fats are preferable when battling cold weather.  Our modern penchant 
for lean meat comes, at least in part, from the erroneous belief that 
fatty plaques on blood vessel walls come from eating fats. This 
unfortunate paradigm leads to the poor medical advice to cut back on fat 
consumption when patients show either signs of claudication of blood 
vessels or blood lipid profiles that are mildly suggestive of cardio risk.
Best Wishes,
Ron
