Question

LUULEL.LILILOW D O I ULUULUULU The Inuit (formerly called Eskimo) people live on a nearly exclusively protein/fat diet. The protein comes from various sea animals and the fat from mammal blubber. The only real carbohydrate sources are limited to a very short "summer" period during which they can gather various berries type vegetables and fruits. They exhibit no significant ketoacidosis, or attendant side effects. Can you concisely, efficiently explain how this may be from the metabolism we have studied? If so, do so. I recommend you write your answer on separate paper, then edit

Answer 1

First point that I want to bring to your attention is that those people are living there from a long time and their ancestor have been following such diet efficiently which also suggest that genetics play a role here . But now coming to biochenistry of this situation.

Those people solely relay on protein and fat. Both of which they get mainly from wild animals as you mentioned in question. Now, We are thinking that how can they tolerate such high content of fat and protein right there are main two reasons as below

1)wild animals eat freely whatever nature provide their fat content (aquatic animals) is far more healthful and less of their fat is saturated unlike case of farm animals and packed food that we consume. And more of their fat is monosaturated form(like olive oil). Also their fat is rich in Omega-3 fatty acid and one more information that whale blubber contain 70% monosaturated fat and 30% omega-3. This shows that their fat diet is way more better.

2)Now coming to toerence of high protein and fat content. They lack carbs in diet which is efficient source for getting glucose. But obviously their body has to work and acquire glicose which they get from conversion of fat and protein into glucose by process of gluconeogenesis. But they need of high conversion rate due to lack of carbs which is handled by their large size protein and accumulation of waste is handled by a large amount of urine passage which remove large amount of urea produced.

I hope it was helpful, if it was give a thumps up. All the best.
