Any reliable medical studies to show that protein really makes a difference?

    My dad's a doctor and I was talking to him and he figured it probably didn't really make a difference with weight lifting/building muscle except for maybe people who are really hardcore into it. Additionally, he told me that consuming too much protein can actually be really hard on your liver. He said I probably wouldn't notice a difference whether I was getting a gram/lb bodyweight vs. just eating normally.

    Is there any info that backs up the use of protein (especially protein shakes) when building?

    makes a difference VS what? if you can consume enough protein from food.. you dont need shakes. but if you keep in mind you need 1-1.5g of protein per lbs of body mass(lets say LBM so a 220lbs person at 10% is 198lbs of lean body mass. he has to eat 200-300g of protein a day. do you know how much " normal food that is"? .. so they take shakes as meal replacements.. understand?

    He doesn't think it's necessary to consume that much protein. He thought it would be detrimental to your liver. In his opinion, you wouldn't notice a difference in your gains consuming tons of protein vs. not consuming tons. So he asked me if I could provide him any information that says that consuming that much protein really makes a considerable difference in gains.

    too much protein can be hard on kidneys, without adequate water intake

    as far as clinicals on high protein diet
    most indicate 1.5-2g/kg as adequate for resistance training athletes

    really depends on what eating normally entails protein intake wise. if you are eating a lot of meat, milk and egg products then the difference may not be significant.

    Athletes and active people need more protein than the average "sedentary" person. This is a known fact. So for him to say that there's not gonna be a difference whether you consume a normal amount of protein (50 grams a day, I believe is the guideline) versus more is ... wrong. /thread

    Google the benefits of whey protein, bro.

    I have. I've read the stickies as well. I'm looking for something to substantiate to my dad with other than just stating benefits like muscle recovery.

    he's so right, your body doesn't need protein to build muscle tissue. good luck with your training bro, you know it all that's fo sho

    i'm pretty sure twinkies will provide the proper fuel for muscle tissue


    my uncle is a plumber and he says that lifting weights doesn't help build muscle, in fact it may cause brain tumors.

    I don't really understand why you guys are giving him hell. If you make a claim that a professional does not believe, said person will ask for clinical proof. Studies are performed on everything you can think of --- coming across the benefits of a higher than RDA protein intake should not be that hard to come across.

    or the dr could provide studies saying it doesn't help instead of just spouting off with half ass incorrect comments

    I actually have an old excel spreadsheet i worked on in college dealing with this but it might take me a few days to dig it up and the math and science behind it is probably faulty because i was a young grad student at the time dealing with biochemistry issues when i was a polymer science major.

    Your dad is right.

    I'd love to see anyone here state otherwise, and back it up. (note: They can't, hense all the hate.)

    Your body only needs X amount of protein to build muscle. Consuming more does not = building more muscle.

    That number has NOT been established through a medical field, but it has been established that within healthy adults that the difference between taking 8 and 1.6g/lb does not make a huge difference.

    It has been argued that it's MUCH more important to make sure that your body has a constant supply of protein, rather than making sure of how much you eat.

    This has 2 benefits - 1. You don't go catabolic. 2. You never ingest enough at one time to potentially hurt your body.

    :dunno: what strikes me as flawed with that argument is that it's pretty common for bodybuilders to pay attention to macro nutrition and try to get 30% of their cals fro protein right?


    Well if you're 250+ and eat 5000 cals a day just to maintain, 30% of 5k cals is a shitload of protein to be eating, and probably way more than 1g of protein per pound of bodyweigt.... so is macro nutrition just bs or is it a good thing to get more than enough protein?

    also, if I have 30g protein from whey plus 20g from milk every morning with my breakfast, is that too much if i'm 200lbs? :noes: I figure milk protein absorbs slower to some extent

    Agree with you here.
    I think Lyle adressed this as well... going by percentages is a flawed way of doing it the further I guess you are from your maintenance intake.

    I know too much protein has been purported to be stressful to the kidneys but wasn't aware it was so to the liver. I read protein only has to be restricted in the case of hepatic encephalopathy.

    Define "too much" as far as kidney problem go. Up to 35% of the calories from protein is inside the range that the Department of Agriculture suggest and on a 3000 cals diet it means that around 250g of protein/day can be eaten.

    1.8g/kg (.8g/lb) seems to be the sweet spot though, that's what Dr Lemon, a specialist of protein intake, says.

    "Going catabolic" is not only determined by protein intake.
