      i tried but youtube needs a sliding scale playback manipulator and i would put it on like 95 so it wouldnt sound choppy. all though i will admit i like the speed most times...you can get into a serious groove but you have to listen to it multiple times but they intend for them to be replayed and paused. the issue is the youtube playback thing i wish they would make it like MX player but im sure it would be more difficult or they would have used that type of system first.

    If I could, I'd give this a million likes. I can't like it enough. A single "like" is terribly insufficient. This video will be incredibly helpful to my students when we cover diabetic medications and cholesterol drugs (which of course, are only used when diet and exercise aren't enough). Based on the responses I see here in the comments, it's clear that many people have had experience with diabetes-related and nutritional issues. But that would be an entirely different CC series... I don't suppose there are any diabetologists or registered dieticians out there who want to work on that series?

    Hello. You mentioned that in the post-absorptive state, the body launches gluconeogenesis in order to restore the blood glucose levels by making glucose from amino acids. However, I assumed that in the post-absorptive state, your body would want to break down the storage glycogen to produce glucose through glycogenolysis. So my question is, why does the body prefer gluconeogenesis in this state over glycogenlolysis? Thank you.

    Did You Know?
    Anaerobic Cellular Respiration creates Lactic Acid! When it does, the Lactic Acid is stored in your muscles, which is why people who are new to working out or people who work out rarely get sore muscles. The more you work out, the more efficient your cells become at Aerobic Cellular Respiration, which is why people who work-out a lot don't get sore!

    The neurons can not only rn exclusively on glucose. About 60% of their energy can come from ketones(fat) and it even has some improvement in cognitive function. The rest can always be made by gluconeogenesis

  • @OptimusSime

    • @diablominero
      @diablominero 5 ปีที่แล้ว +1

      Your brain will demand a very small amount of carbohydrate even if you aren't eating any, which your liver makes from protein or glycerol via gluconeogenesis. (your erythrocytes actually need glucose, whereas neurons mostly just prefer it, but erythrocytes have tiny demands) But it'll get the majority of its energy from ketones. If your brain can't get energy, it'll get damaged.

    I love your videos, Hank & team, I am watching so many of them and am learning a lot. But Hank, are you trying to compete with Eminem? It takes an enormous effort to follow everything you say... I have to pause and rewind because if I get distracted for one second, I miss an entire paragraph!
