    No idea where you got this from.

    Thermogenics of food conversion requires up to 30% for protein, 15% for carboydrates and only 2% for fat, which is why fat is stored so easily in the body when consumed to excess.

    Eating 100g of protein will at minimum utilse 70% of what you've just eaten not 42%.

    Protein alone will not prevent muscle loss, nitrogen and a few useful amino acids play the part as well as carbohydrates and glycogen.

    I see you are the person on the cereal diet, I don't think protein thermogenics should be a concern for you at the moment considering what you're eating, you are not getting the correct nutrients, unless your post about the cereal diet is inaccurate.

    These are some sources:

    I think you're seriously misinterpreting this information, which appears to be the result of a google search of 58% and protein, and other forums are not "sources". It is talking about protein conversion to glucose, which only happens under the very specific conditions of extreme low carb/low fat and/or starvation.


    I just found a book

    Nutrition and Diet Therapy: Self-Instructional Approaches
    By Peggy Stanfield, Y. H. Hu

    This is the entire principle of the Dukan diet.

    The dukan diet, I'm pretty sure, is extreme low carb/low fat, which would be one of the conditions for protein to convert to glucose. This does not mean that only 58% of protein counts in a regular diet, at all. Especially not on a cereal and protein diet.

    the point of those articles is not to say you only absorb 58% of protein you ingest. It is saying that your body is a complex machine. If you ingest 100g of protein, and your body needs 100g of protein to rebuild muscle, it will use 100% of the protein AS proteins. ONLY in situations where your body NEEDS sugar (to replenish glycogen for example) it will look for available sources. If it finds spare protein that is NOT being used to repair, it can convert up to 58% of it into the necessary sugars to convert into glycogen. If there are NO proteins available to convert, it will attempt to convert fat, but it does so less efficiently (one article said 10%-ish), and as a last resort it will resort to using any available amino acids it can find, at this point usually from broken down muscle tissue.

    This process is NOT a hard set number. It is based entirely on your particular body's needs and the amounts of each available component..

    HOWEVER, even if you convert 58% of the protein you eat. it does NOT mean you only absorb 58%. it means UP to 58% is converted to sugars (carbs), the rest is still absorbed, but stays in the form of proteins.

    Or if you want to get thin, eat lots of cheerios like you said in your other thread :indifferent:

    Man, I was soo hoping to get a full 3g a protein from a serving of cheerios!!! lol

    I was simply sharing some information to help other people with their goals and sharing a fact regarding basic biochemistry. Unlike you I am trying to help people by sharing information not criticize them.

    If you want others to take you seriously, perhaps you should state your information in the form of a question to see if others (i.e. people with degrees in the topic) would agree or disagree and, also, state your sources with your original query...again, asking whether information is valid or sparking (justifiable) debate.

    On your own searches, please remember that if there was a magic number or numbers for nutrients and weight loss across the board, MFP would probably not exist and everyone would probably be at the top of their physiological game.

    In all honesty, good luck with your search, but please remember to read into your sources to find where they get their funding. Research doesn't pay for itself, ya know! ;)

    I would like to share a fact on protein for everyone's benefit and that is that you should include large amounts of protein in your diet. Why? well it is actually very simple first of all protein helps prevent muscle loss but secondly only 58% of protein can be used for energy when metabolized by the body. In other words if you hypothetically consumed 2500 calories of lean chicken breast you would actually only be consuming 1450 calories of usable energy. If you want to get thin eat lots of protein.

    The *kitten*?

    I think this is a clear case of "I read something, I don't exactly understand it, but I'm going to regurgitate it."

    Normally I would gladly jump on this and tear it apart but the intent and principle is correct "eat more protein if you want to lose fat". Now I'll keep this simple as to the why's, and source everything:

    -It helps you lose fat.
    (see: http://www.ncbi.nlm.nih.gov/pubmed/19179060 and http://www.ncbi.nlm.nih.gov/pubmed/18469287)

    -It helps you build muscle.
    (see: http://www.ncbi.nlm.nih.gov/pubmed/19150856)

    -It fills you up so you’re less hungry, moreso than pretty much anything else you could eat.
    (see: http://www.ncbi.nlm.nih.gov/pubmed/14557793 and http://www.ncbi.nlm.nih.gov/pubmed/18469287)

    -It supports lean body mass (muscle) over flabby and unhealthy body mass (fat), making you lose more fat and less muscle on a caloric deficit.
    (see: http://www.ncbi.nlm.nih.gov/pubmed/19927027 and http://www.ncbi.nlm.nih.gov/pubmed/15640518)


    Now, this is all documented in a much larger document that I occasionally (read: allthef*ckingtime) post on various thread and insist people read. http://4chanfit.wikia.com/wiki/Harsh's_Worksheet_(WIP)

    Thankyou for helping make my point. And as Fausttt stated the body used nearly 100% of protein calories when it keeps it in protein form to build muscle tissue but if the body is in a calorie deficit and decided to use some protein as a source of carbs then it breaks it down with a 58% efficiency into glucose.

    Lol 58% eh? So if I had one gram of protein for the day your body would use about half of that gram?

Anyway, nowhere does it say in any of those articles that everyones body can only convert 58% of protein to energy...I could randomly spit out facts too. Everyone uses 2% of their brain. It's true! Because some people use at least 2%, and at the point you die there will be some instance where only 2% is being used.

    On that note Thermogenesis dealing with DIT and TEF is pretty N.E.A.T. hey?

    Or you can just continue to believe a calorie is just a calorie.

    If I'm not mistaken you're just talking about the amount of protein that can be coverted to glucose via gluconeogenesis.

    If you're using protein as a primary fuel source you're going to be consuming very high amounts of protein because by default, you're consuming too few carbs to fuel energy.

    In other words, if you're consuming adequate carbohydrate, you're not going to be using protein as an energy source at least not in any massive quantity. If you're not consuming adequate carbohydrate, you will likely convert some protein to glucose for energy needs, but you're also going to be eating much more protein.

    Is there a practical application to what you're trying to present? (Trying to understand the point of this post).

    Lastly, a calorie is a calorie when it goes into your mouth. Your body does different things with each macronutrient depending on need. This doesn't change the value of a calorie.


    EDIT: And I'm relatively certain that this is where the concept of the phrase "Carbs are protein sparing" comes from. Adding carbs MAY prevent additional use of protein as an energy source which allows more protein to be used for skeletal muscle/non-energy needs.

    If this is true, how much protein should I be eating?

    I weigh around 120 kg.

    Calculators say I should eat around 180 grams of protein. BUt when I weigh 90 and 60 kg later on, will I still be eating 180 grams of protein?

    I find it hard to eat that much protein.

    I would like to share a fact on protein for everyone's benefit and that is that you should include large amounts of protein in your diet. Why? well it is actually very simple first of all protein helps prevent muscle loss but secondly only 58% of protein can be used for energy when metabolized by the body. In other words if you hypothetically consumed 2500 calories of lean chicken breast you would actually only be consuming 1450 calories of usable energy. If you want to get thin eat lots of protein.
    ...can you cite some valid research before I jump the gun and wet my pants?
    And will all this protein mess up my cereal diet?:laugh: :laugh: :laugh:

    If you do not believe me look at anyone who has successfully completed the dukan diet. Regardless this was just information to assist people it does not relate to my plan in partucular

    Links to sources, please. "Looking" at someone proves nothing. While I can appreciate you trying to help others, it's not useful if you don't show me the science.
