    I had a kinesiology student at my school today tell you that you can only absorb 15 g of protein per meal, the rest gets excreted out of your system. At first i was kind of:hsugh: but after googling and such I can't really find any information backing up that this is the case or isn't.

    Anyone ever heard of something like this, or have any articles proving it wrong or right?

    I personally don't feel this is correct... that would be pretty retarded to keep all meals down to 15 g of protein.

    The last i remember reading on the subject was that there is no research to show how much the human body can absorb over a specific amount of time.

    How do you define a meal, anyways? I can eat once an hour and get 15 grams of protein per "meal" but eating once every three hours with 45 grams of protein per meal won't work?

    The human body does not get rid of good useful calories.

    you'll absorb pretty much everything you ingest. youre not absorbing food the instant it hits your stomach. it travels through your entire digestive system and your body will make use of whatever is there.

    He's actually a pretty big guy and goes to the gym everyday, he doesn't have huge numbers but they're respectable.

    I dunno, i'm going to try and find something, but i dont think i will :wtc:

    You're body "absorbs" all of the protein you eat, it's just stored until you need it.

    Ya, see thats the opposite of what he is saying, he says there is a maximum amount you can "absorb" and the rest simply passes through "unabsorbed" ie. all absorption pathways are saturated with protein. Do you have a site or study backing this up?

    My anatomy book. :dunno: Too lazy to get it out of my car right now though. Your body is a smart machine, though. It stores carbohydrates, fats, and proteins for later use. Nothing it needs will go to waste.

    That's good enough reasoning for me, I mean, its not like i don't enjoy the food I eat, and I'd rather have too much protein than too little.

    True, the way i see it is that say you eat a chicken breast, that breast doesn't instally get digested. It takes your enzymes a while to get through the chicken breast, meanwhile the amino acids released get passed onto the small intenstine etc etc.... you're going to have a steady stream of nutrients for your body.

    I wouldn't think more than 60% would get deposited as waste, i mean, those would be some massive shits :run:

    a larger meal just sits in your stomach longer

    excess protein cannot be stored, its broken down

    I thought amino acids couldn't be converted into fat and sugar.

    :werd: and excreted. As to the original topic, I remember reading a study that the protein retained at 180g per day eaten was ~6g/day which was double the ~3g/day retained when only 80g/day was eaten. Now somehow, I doubt the person eating the 180g/day had it in 10 seperate servings. Your body has an amazing ability to digest any macronutrient that you put into it, therefore, increasing the amount of protein in a sitting will increase the free amino acid pool after intake, however, after a certain point this isn't going to help. Think of it as attempting to add more to a fully saturated solution, it just doesn't help. Also, remember a meal can continue to elevate these levels for up to almost 8 hours after eating if it is a slow digesting protein, so it isn't like eating a few chicken breasts is going to immediately introduce 60g of free amino acids into your system.

    It can and is. However, the energy it takes to perform this is less than ideal. That is why it is better to eat an extra 200cal of protein than to eat an extra 200cal of sugar
