You need carbohydrates for energy. Glucose is the primary source of energy for almost every food consuming organism. Too much sugar is harmful, yes, but don't say things that aren't true.

You don’t need to consume carbohydrates for energy. You can live off of fat and protein.

  The Eskimos traditional diet is a good example of this. Their diet also includes organ meats, so they got all of their vitamins and minerals in good amounts.

      "Carbohydrate accounted for only 15 to 20% of their calories, largely in the form of glycogen from the meat they consumed."

  > no you don't. https://en.wikipedia.org/wiki/Gluconeogenesis https://en.wikipedia.org/wiki/Gluconeogenesis That doesn't refute his argument. > yeah, those carnivores consume so much carbohydrates! Fresh raw meat actually has a good amount of carbs. The muscle glycogen (animal equivalent of plant starch) starts to turn into lactic acid after death, but it's there for a carnivore that immediately starts eating after the kill. Also carnivores have jacked up gluconeogenesis. Carbohydrates are vital for carnivores who need to use anaerobic energy system to catch prey. They might not be vital for coach potato ketoers. People usually claim that Inuits somehow survive without carbs but that's not true at all. Inuits are eating 15-20% of their calories as carbs in the form of muscle glycogen: https://academic.oup.com/ajcn/article/25/8/737/4733245 https://academic.oup.com/ajcn/article/25/8/737/4733245

    > That doesn't refute his argument how come? gluconeogenesis is how body gets glucose from non-carbbohydrate sources. his argument was "You need carbohydrates for energy". you don't. > muscle glycogen fair enough. the comment about carnivores was not entirely correct.

      > how come? gluconeogenesis is how body gets glucose from non-carbbohydrate sources. his argument was "You need carbohydrates for energy". you don't. The body can create fat from carbs and protein via fatty acid synthesis. Does this mean fat in diet is unnecessary? Of course not. Similarly, there existing a pathway for creating carbohydrate from fat and protein doesn't by itself prove that carbohydrate is unnecessary.

        > Does this mean fat in diet is unnecessary goalpost has shifted? his wording was "body needs carbs for energy". no, body doesn't need carbs for energy. besides, there definitely are essential fatty acids that our body cannot produce and cannot survive without, so you're wrong implying that body can survive without fats just like it can without carbs. there are no essential carbohydrates.
