    I was listening to a bodybuilding podcast and they had Scott Connelly on there. He is the guy that helped engineer Metrx from the getgo and has now come out with a new product called Progenix. Its supposed to be really good but havent tried it.

    Anyway he was stating that our bodies were not made to have to have carbs. Now I am not talking about Adkins here, but I guess it does relate....but he was stating that having good "clean" protein produces enough glucose for your body to supply itself with energy.

    He stated in the Lewis and Clark expeditions diary how they only had meat to eat for the majority of their expedition and how great and robust they felt, and what great shape they were in.

    I know Dave Palumbos plan (he does nutrition and stuff for bodybuilders) he advocates this plan as well but he emphasized having alot of the good fats like almonds and etc. which also produces energy for your body without it turning to fat.

    How important are carbs to you? I know I battle with them. I know there are good carbs like broccoli, sweet potatoes and etc., but I crave fries, and all the bad carbs. I have been able to ween myself from them before and I will do it again.

    Are any of you carb free and is that a main reason you stay lean?

    That is crock of shit. Your body use carbs for energy and well as your brain uses 100% glucose. sorry, some of you body builders/ low carb-high protein zombies, have a blank stare must of the time. I said 'some' not all. it really screws up your body when you delet a micro nutrient out.

    just stay away from empty carbs/high glycemic, anything 'white', white flour, white sugar. use 'whole grain' kamut, splet, quinoa, pastas and breads. very high in protein and B vitamins. They are also know as , Ancient grains, how do you think those pyramids were built? not by protein only.

    everything in moderation, it isn't 'an all or nothing' concept. i know it's 'simple' concept, but so ignored.

    Connelly is a big dork. Seen him at the local shopping and buying carbs, and had friend that worked for the monkey at Metrx, back in the day. he's just selling a 'gimmick', with NO valid study done. It's not easy selling 'simple'. or everyone would be doing, so they 'sell' stupid and everyone gets on the band wagon.

    But, hey, if gives me a lot of business, fixing everyone diets, from all the bullshit that is out there.

    I've always read that with every meal, you should consume carbs, fats and proteins in moderation to what your goals are. They are somewhat important to me for energy and growth.

    I expect to see a posting from Chucky here in about an hour. icon_lol.gif

    Personally, I can't imagine life without my carbs -- good carbs, bad carbs WHATever -- I like my pizza, pancakes, ice cream, cookies, bread, etc too much. Everything in moderation works just fine for me.

    Now, someone pass me the chocolate chip cookie dough icon_lol.gif

    From a biological point of view, humans are quite clearly omnivores. The length of our GI tract compared to our body size, the variety of types of teeth we have, the amazing range of food products on which we can thrive, etc. all make it obvious that natural selection has molded us to eat some of just about anything we encounter.

    It's possible to synthesize glucose from non-carbohydrate sources, true. That's the pathway of gluconeogenesis, and in humans happens almost exclusively in the liver. In fact, it's happening in you almost all the time because the body's primary source of energy is glucose and the brain in particular (but also the skeletal muscles and the heart, which also are barely capable of gluconeogenesis) has such a spectacularly high demand of glucose that even with a diet containing a large amount of carbohydrates your blood sugar levels need to be maintained by pumping in more glucose. Gluconeogenesis can act as a way to buffer against sugar crashes following insulin spikes. Switching to an extremely low carbohydrate diet often increases the stress on the system; amino acids, while the building blocks of the vast majority of things your body synthesizes, are actually somewhat toxic and your body is constantly dealing with ways to get rid of the excess nitrogen. The nearly-exclusively-meat diet of the Inuit and the Eskimo peoples seems to be linked to a variety of health problems later in life.

    In general, go with moderation. Your body can handle basically any nutrient source you throw at it for a short time. But over the long haul, you're probably better off balancing your nutrition between carbohydrates, lipids, and proteins, and most people seem to need less in the realm of proteins to maintain themselves than they need of either lipids or carbohydrates. And if you do decide to restrict your carbohydrates, I continue to feel that it makes much more sense to worry about your refined carbohydrates than your raw ones. There's a difference between refined cane sugar and an apple, and between white flour and whole wheat flour. Any diet which tried to tell me that I can eat as much bacon as I want but should limit my intake of carrots and bananas is somewhat suspect in my mind.

    your red blood cells (erythrocytes) also feed only on glucose. Like UStriathlete said, they are very important.

    Your body need more carbs than protein, and you also have to include fats.
    everything in moderation.

    Carbs are the most important source of energy, more so than fats and protein. even "bad carbs" in moderation is as important as the "good carbs".

    protein is over-rated, look at who is preaching, an engineer from a protein supplier.

    I wouldnt be surprised if he was coerced by his boss to spread such nonsense.

    wow, well this is interesting to read.


    Basically Carbs are essential for living no matter what and are a NEED in someone's diet. Carbs do soooo many things within the body, without them, or even lower amounts, the body cannot function normally or at all. (brain function/thought gets energy from carbs too)

    Energy expenditure is mostly consistent of carbs. These are rough numbers,

    60% of one's diet should be carbs
    15-30% fats
    about 15% proteins.

    Although fats provide the most ATP (energy) per kcal in general, Carbohydrates are the preferred substrate for providing energy since they provide more ATP per unit of Oxygen and is a quicker process (aerobic glycolysis). If you want to know more about the physiology of it email me.

    Carbohydrates are a need.. and to completely rid them of one's diet is foolish. The atkins diet.. although it may 'help' people loose weight.. is not the healthiest means of doing so. I should probably elaborate more on the subject, but high protein diets aren't the safest, and carbohydrates should be included in almost every meal and stated earlier. Also you should never have just one type of food, so to reiterate, you should have carbs proteins and fats, or a combination of the two, with whatever your eating.

    there is no physiological need to consume carbohydrate/sugar - i am not saying not to eat carbs, but people do not have to in order to survive. you can eat fish, coconuts and greens and live pretty well. the body will convert any fat and protein to glucose that it needs.

    we evolved only eating sugars from fruits, bee hives and roots. humans lived through long winters eating only meats...some still do. where do they get their daily glucose needs for their brain? from protein and fat... grain consumption, especially processed, is new in human evolution.

    i am about to make some sweet potato hash browns...

    Carbs are essential for our bodies to survive
    without them we have to catabolize or breakdown other materials or our own bodies to continue to live
    when we go on a pure protein diet the protein must be converted into glucose
    which is the simple sugar our body uses and when in excess is converted into fat stores
    but the protein must be denitrogen-ized and this discarded in the kidneys

    I don't trust or listen to anyone who says "under no conditions and at no time should you ever eat X," unless X = arsenic/poop/oysters/lead-based paint. Any diet or meal plan or whatever that entirely prohibits one thing or another strikes me as inherently simplistic, and I don't take counsel from the minds that devise them, because the people preaching it are the intellectual inbred-bastard-children of those who once said "oh, everyone will be healthier if they just cut fat 100% out of their diets!" It's grossly reductionist, it spawns destructive neurosis, and-- as the zero-fat-EVER crowd showed-- in the long term it won't work.

    You don't "fix" something as complex as human nutrition by declaring a fatwa on carbohydrates.

    you have confused the term carb with grain and the term meat with protein. they are not interchangable.

    fish coconuts milk and green vegetables do contain carb. rice, bread, pasta has protein in it as well.

    Does not matter, the body can convert fat and protein to glucose, that was the point. The grams of carbohydrate that are stored in muscle tissue, nuts, etc would not be enough to sustain life if in fact we required it and did not have the pathways to convert the others to glucose. Coconut was a bad example because it does have a lot of sugar. If I am totally wrong and did not listen correctly during 4 years of ochem, biochem, inorganic chem and human physiology then I appologize to all.
