  1. Hello Everyone, I was just curious to know if there are any
    knowledgable people out there that can explain the above
    subject to me in more detail. I would like to try it, but am
    sceptical there isn't enough research information out there
    to back up trying to go into a state of ketosis. I exercise
    quite regulary and am a undergo regular weight training. Is
    this lifestyle choice a bad one cause of low Carbohydrate
    levels? Any advice from anyone, or especially people who are
    quite sports oreintated, please post feedback. I'm a healthy
    24 year old with no family history of heart problems under
    55. Thanks in Advance John

    That pretty much explains the low IQ problem.

    Ha, ... Hah, Ha!

    Just my opinion. But, I am *right* as usual!

    So if one or two or even twenty people here say, hey, it
    works for me, you'll go ahead and starve your body of
    carbohydrates until it burns protein? Not trying to flame
    you, just checking your logic. Something about us humans
    seems to trust an anecdote ("my grandmother smoked until she
    was 90"😉 rather than research across a population. I did
    some research on ketosis on the net a while back and found a
    lot of info out there. It does seem to take away a lot of
    weight for people with serious obesity. I think there's too
    much potential for damage. While the rest of the body can
    switch to ketosis for energy, the brain needs glucose. There
    are people who think that ketosis is actually a natural
    state, and there's even a scientist, Richard L. Veech, at
    the NIH who is trying to prove this, that we as prehistoric
    humans regularly starved, and the agricultural revolution
    has locked us in an "unnatural" state. He believes that the
    brain works more efficiently on ketones.

    The brain can use ketones, too. And any additional glucose
    requirements can be easily met by protein, which converts to
    glucose, just less efficiently and completely than carbs.

    There is no such thing in human nutrition as an essential
    carbohydrate, just essential fats and proteins.

    Some carbs can be part of a healthy diet, but they aren't
    necessary.

    I was beginning to wonder if this was a default attitude on
    this NG for dealing with someone who says something
    incorrect. I just associated, as I was writing the sentence,
    ketosis with starvation and protein catabolism, as the
    medical establishment has for years. But I can change,
    really I can.

    I don't claim to be an authority, but let's listen to
    someone who may be:

    "Maria C. Linder is on the faculty at California State
    University Fullerton, California in the Department of
    Chemistry and Biochemistry. All quotes are from her
    textbook; "Nutritional Biochemistry and Metabolism: with
    clinical applications", Maria C. Linder. pages 87-109.
    Chapter Eight: Nutrition and Metabolism of Protein."

    "Early in fasting glycogen reserves are depleted, and
    protein (mainly from muscle) becomes the major source of
    carbon for glucose production. Glucose is required in
    substantial amounts by blood cells and the central nervous
    system on a daily basis. There is also an initiation of
    ketone body production by the liver to provide a more water
    soluble form of fat-derived fuel."

    "DIETARY PROTEIN LARGELY OR FULLY SUBSTITUTES FOR MUSCLE
    PROTEIN IN GLUCONEOGENESIS."

    ""The body adapts to starvation and reduces the need for protein-
    dependent gluconeogenesis by boosting its production of
    ketones, a fuel ALTERNATIVE to glucose for MOST CELLS.

    Circulating ketones reach maximum levels after about ten
    days of fasting and now substitute for much of the glucose
    requirement of the central nervous system. This drastically
    reduces the need for catabolism of muscle protein."

    "With reduced protein catabolism, urinary nitrogen
    excretion also declines. And there is a shift from the
    excretion of urea to a predominance of ammonia loss. This
    shift toward ammonia versus urea parallels the increased
    production and excretion of keto acids, and serves to
    MAINTAIN ACID / BASE BALANCE."

    "The overall point is that muscle is a valuable reserve of
    carbons that can be used for glucose production when needed.
    However the body prevents excessive losses of muscle protein
    over long periods of fasting by adapting the central nervous
    system to utilization of ketone bodies for fuel."

    What I take from this is that the body may simultaneously
    turn to muscle protein and dietary protein while it is
    adjusting to ketosis. Once ketosis is in full swing, then
    the need for protein catabolism decreases. Is it less than
    when the body was a glucose machine (since there is always a
    baseline of protein catabolisis going on at any time- right
    Mark? Some amino acids are known as ketogenic*, right Mark?
    )? I don't know. Does anyone have the answer for that? It
    could be different for each person. Is this a good idea for
    bodybuilders? I don't know. I think maybe- but then I'm not
    sure, because I haven't taken the time to know everything-
    that some bodybuilders, some athletes, some of the greatest
    sports performers ever have been able to do what they do
    without ketosis. Maybe our good troll knows, and maybe he'd
    like to teach us something, or would he rather spew more
    profanity and poison about the group?

    I will admit my error on the brain's use of glucose: it will
    use ketones, and from what I've read, the brain and many
    other organs will prefer to use ketones for fuel when they
    are available. This may support the argument that ketosis is
    "normal," but maybe it is just another way to control the
    level of ketones in the body - i.e. "get rid of these
    first." I don't know. Just thought I'd throw it out there
    for discussion. Am I allowed to discuss things here, with
    the possibility of making an error, or do I have to know a
    lot of things and insult people that don't?

    The gist of my original post was only this: yes, be
    skeptical. Yeah, I'm a danger.

    Thanks JC, You did well to correct some parts of your
    earlier mistake. Could it be the efficiency of the body to
    utilise ketones the result of why some people tend to stay
    leaner then others (once genetics and muscle mass is ruled
    out). Just a topic of discussion. John S
