Default how much protein can your body absorb?
I am trying to get enough protein / day. I have heard you should be having 1 gram / lbs.

It's pretty hard to get 150 or so grams of protein so i'm wondering how much protein can you absorb in one sitting? If i take two scoops of protein powder instead of one at 30grams per scoop that would give me 60 grams. Can I even absorb that much in one drink?

thanks!

see, it entirely depends on your body, there is limit to protein absorption also. if your body is used to absorb 150gm of proteins and suddenly you increase it to 500...that means that you are over consuming. and with excess protein, your body becomes less efficient at processing it and uses much of it for energy, If you consume small amounts of protein, your body becomes extremely efficient at using that protein and burns less for energy.

The biggest protein myth is that you can only digest 30 grams of protein at one time. Find out what's wrong with this belief and just how much protein you need. This is a common question. I also get variations such as, how much protein can you digest at one time?

There are two ways to answer this, because there really two questions being asked.

1) How much protein can the digestive system physically absorb into the bloodstream from a meal?

And the MORE IMPORTANT QUESTION...

2) How much protein can you body actually utilize?

The answers...

1) About 95% and higher, unless you have some type of digestive system malfunction.

So if you get convinced by supplement companies to drink a 42g protein shake in 5 minutes, you'll still probably absorb at 38 or more grams of that protein.

Your muscle growth is not limited by the amount of protein you can DIGEST or ABSORB.

Your muscle growth IS LIMITED by the amount of protein that your body can utilize for protein synthesis.

So the answer to #2...

2) A lot less than you think.

You really don't need 40, or 30, or probably even 20g of protein per meal to keep your protein synthesis humming along. See Nutrition Help Expert Brad Pilon's post on "How Much Protein Do We Really Need"

Any protein that your body can't use for growth will be shuttled into a process where it is broken down (de-aminated: meaning the nitrogen is removed from the molecule and it becomes a carbon skeleton) to be used in energy pathways.

Now, there are benefits for eating extra protein (in my opinion) when dieting, mainly that it helps to suppress appetite.

But the bottom line to the question I am asked almost everyday is...

a) Your body can digest and absorb almost all of the protein you eat without problem.

b) Your muscles can only do so much with protein...the muscle growth process is RARELY, if ever limited by the amount of protein we consume. Almost all of us can easily get enough protein for maximum muscle growth without the need for eating 50g of protein 6 times per day. Ronnie Coleman, Jay Cutler, and Gunter Schlerkcamp excluded, of course.

Overall, I'd think twice about the need to slam down a 40-50g protein shake...just think of the children and puppies you'll save by not gassing them out with protein farts.

Real food should cover all your protein needs.

I will advice you to take small portions rather than big portions at one go.
I don't know how much protein a body need but eating a complete meal is enough per day.

I would suggest a small portion for 4-5 times a day. There's no benefit that you will get from pushing your body, and your muscle will grow normally if you have a balanced meal plan

Well, I've had different people tell me that to lose weight, you have to increase protein, and that it takes more energy to burn protein than other foods. I've read things that say you can get too much, but it would take an awfully lot of protein to get that much. If you're reducing overall carbs in your diet, you have to eat something to not be hungry and to eat enough calories in the day. I do try to drink a protein shake on the days that I do strength training. I don't think it's had a dramatic effect on weight loss, lol. If it has had any, I couldn't say it was specifically the protein or not.

I read that too much protein is not good for the body so how much protein does a normal need in a day?

Protein requirement varies depending on age, gender and activity level. As a general rule, adults must have 0.8 grams of protein per kilogram of body weight.
