I heard it was a myth...

...that you can only digest 30g of protein per meal? Has anyone else heard of this?
I ask because I drink a protein shake every morning. at 24g of protein. Would it be okay to have 2 scoops and make it 48g? or is it better to spread it out and drink one 24g protein shake in the morning and another 24g one later?

    never heard of this before sorry though im sure in which the vessel that the protein comes may be a factor... i.e. liquid form/solid form
  • I am not sure about the whole 30g of protein pure meal but I do know how to calculate the suggested grams of protein you should have in a day. Take your current body weight and multiply it by 0.8. If two scoops of protein puts you over that for the day I would resist if not go for it.

    I've never heard this before either, sounds silly to me.

    I always go over my protein, and it has never been a problem.
  • I have heard that myth about 1000 times xD It doesn't absorb directly as it hits your stomach. Whey digests fast though. If it fits your macros why not?
  • I never heard of it either & I'm pretty much sure that is a silly myth. We need to eat at least 0.5g of protein per pound of weight a day so a 30g alone is way too low. My diet consists of 30% protein which equals to 122g per day or slightly more than 1g per pound of weight. And I never get anything other than an improved body composition & more muscle definition.
  • The only thing that over-protein'ing (lol) does for me is give me wicked gas :laugh:

  • Thank you. Will be reading this more in depth soon :flowerforyou: I skimmed through it and saw the absorption rate for whey was fast. I am assuming that it doesn't matter even though it is whey and can just have my huge protein shake? I don't eat a lot of meat, dairy, or eggs so whey is my main source.
    Also I am only getting about 70g of protein a day. Is this too little?
  • Multiply your current weight by .8 and you will get how many grams you should have on a daily basis.

    I have never heard of this either. I have seen a nutritionist and based on my body weight, age,height, workout schedule and my job: I consume 126g of protein. That is it about 21 grams per meal. I have never had a problem with digesting and I have lost over 25 lbs since January.

    Whey is fast when you compare it to other protein sources, but it will still take 3-4 hours for a 25g dose to fully digest.

    Oh that makes sense :smile: This may sound like a very dumb question, but does it take 6-8 hours to digest the 50g then?
    Still at a loss if 2 scoops of powder is okay :laugh: :laugh:

    Okay? Sure.

    Overkill? Maybe. (Depending on how much you're taking in the rest of the day).


  • Okay? Sure.

    Ah okay. Im only taking in about 70g because I apparently am not a fan of any source of protein. So i thought it would make life easier to get it all at one time and out of the way. I understand though! I proabably should spread it out :flowerforyou:

    If you're relying on shakes for the majority of your protein intake, I would recommend getting something other than straight whey.
    It's best to get your protein from a variety of sources, since each has unique nutritional benefits.

    Trueprotein.com has a product called "Team Skip" which has whey, casein, and egg protein.

    Hey everyone the RDA for protein is .8kg, not g, per body weight. To get your recommended daily intake of protein per day in grams, multiply your body weight by .36, not .8. Of course that's for a sedentary adult, but that's the formula to use and where I assume most people get the faulty idea that you multiply by .8. That's a lot of protein, which isn't necessarily good for you.

    You have a good point! Like I said I think my taste buds work against me on protein. Cannot stand most meats (besides pot roast), hate eggs, and dairy gives me stomach aches :sad: Good thing I came to the boards for advice though!

    That link is amazing by the way :smile: very interesting! Will that help me with the variety part then?

    I would still recommend mostly whole foods, but it would be an improvement.

    Do you eat fish or shellfish?

    I like crab and tuna occasionally. Unfortunately we don't have good seafood here in the Midwest! I like lunchmeat like ham and turkey but there is so much sodium that it doesn't even seem fair :laugh: We do have very good steak here though, I have seen many people on here avoid red meat though, is there a reason for this? I don't really like chicken, torkey, or pork, but who doesn't like a burger right? :laugh:

    No reason to avoid red meat.

    Also, sodium is a necessity for our bodies, especially for those who exercise reguarly. If you are worried, you can up your potassium. It's just demonised around here because of people who have a high sodium day, jump on the scale the next day and low and behold they weigh more. (water weight)
  • I haven't heard of this, but I would probably reccomend aksing a trainer or dietician, or even your MD about it, they would have the most reliabel answer, and could probably help you in figuring how and when to consume your protein so that your stomach doesn't get overwhelmed with having to break it down.

    Agree with this. I eat red meat all the time :D

    And i am trying not to watch sodium. Not weighing in for about a month so i don't pay attention to it now :P

    There is no hard fast rule to the maximum amount of protein your body can take, it all depends on how much muscle mass you have (the more muscle mass, the more protein you can handle).

    That being said, people are taking way too much protein (in my opinion). It is a great carbohydrate alternative, but its still an energy source, and what happens when your body no longer needs the energy? Well if it was a carbohydrate it would store it as body fat, but since protein is really hard to break down into its building blocks, your body just gives up and sends it out of your body. Hence, your spending a lot of money on a fiber alternative... If you want to feel full, eat something high in fiber, you'll save a lot of money and end up eating less calories.

    Unless you have a stomach or digestive condition, your stomach can and will digest everything that hydrochloric acid can break down in the time its in your stomach. IE, everything but insoluble fiber, fillers, and non food items like coins you accidentally swallowed when you were a kid.

    Yes, even gum, actually gets digested.

    When not building muscle, an adult human really only needs (your body can always find a way to use more, but you only NEED) the protein equivalent of 2 oz of meat. I haven't unpacked the book I read that in, so I can't site the source, but multiple studies have established that as the lower threshold for a healthy protein intake.

    The only problems you'll have eating "too much" protein is your sweat might smell like pee because of the amonia your body produces as a byproduct of breaking the protein down, and as mentioned earlier, it will change the smell of your gas.

    OK this might seem a bit ignorant but all this talk about protein etc ... why not just eat a balanced diet with healthy nutritious food. Why are so many people taken in by the Billion £/$ industries which have convinced so many that food alone is not adequate and we have to substitute what we eat with highly processed "shakes" or pills. I am sorry but just make healthy choices. There is so much good food around - I watch the calories, and try to bulk out my meals with fruit and veg. I do not examine any of the nutrition other than fat content which I do not let go above 5% fat per 100g. And that decision is because I have found that eating low fat foods controls my colitis.
