Thread: How much protein can you digest at once?

Anybody ever wonder? Well the answer is nobody knows....Because everyone is different, everyone will digest certain amounts of protein in different quantities. Some researchers in the digestive field told me the believe when a person uses 30 grams of a whey protein concentrate, only 10 grams is actually digested. I will have more info to post here on this subject soon, because its an interesting topic.

At the gym I used to belong to we had a pro female fitness competitor, and this subject came up one time (somehow) while doing cardio. I remember her saying that her nutritionist told her that ingesting any more than 25-30 grams of protein at one time was a waste of protein and money. Like you said though, everyone is different, and I've read lots that just shows there are lots of different opinions on the subject. Good discussion topic

Yes this is very interesting and wondered the same thing. Before I started my bulking phase, I had written down all the cals, carb, etc that I would take for the day. For the first week or so, I noticed that at night time, taking a shake with 50g's or more sent me to the bathroom about 40 min later. Was this a way for my body to say no more or its too much. Leaving me to wonder just exactly how much have I consumed for the day. After a the first week and few days, the bathroom situation stopped. I was using Nature's Best - Isopure- for my protein intake.

When I came back from Aruba, after a week of not using any protein shakes and having to wait just about another week because I was out of my supply, the same thing happened again once I started taking more then 150 g's a day. So I started to slowly increase the amount and this seemed to help my body adjust. Im back to 300 with no problems.

On the scientific side, if you do consume a shake of 25, 35 or 42 per serving, how can you really be assured that you're body will digest all of this? Once you have more info, this will really help because for someone like me who is taking in over 300 a day, I may need to increase this for the total amount that was wasted.

Just when you think you have a handle on something, whammo.

Any chance you will make an I.V. type of protein that we can simply walk around with to make sure we get our daily intake

The part that I've never understood is when people use the term 'wasted,' to describe what happens to the unutilized protein. I mean, when it comes to any macronutrient, you either burn it or store it right? So wouldn't any extra beyond what the body can use just be stored as bodyfat? People talk like the excess just disappears or something. Hey maybe it does, that would be cool!

im sorry if some of this sounds silly, but as I mentioned, im still learning the in's and outs of the protein. This is my Matrix!!

I know that certain proteins will digest slow then others (casein) and some proteins (like whey) will be absorbed faster. Now, is it possible to encase the protein molecule so when the body breaks down the protein, you can actually absorb the full amount? Or maybe 85 to 95% of it?

Also, if some of the protein will be stored as fat, is there a way to force the body use versus converting it to fat? Besides exercise. Another words

lets say for example you have a shake that is
300 cal's, 5 fat, 27 carb and 30 protein, the body picks what it needs and simply stores the rest. If that is correct, is there something that can act as pathway for the protein to enter the muscle

I would think any excess protein would be excreted as urea after protein and amino acid catabolism...rather than stored as fat...but again, I could be wrong.

I like to think that protein intake is a lot like water intake. At some point you become saturated and just can't absorb anymore. A good gauge of water intake is the color of pee. Once the pee goes from yellow to clear, you're pretty saturated with water.

If you drink a ton of water when your pee is clear, you will probably not absorb that much more water but pee a lot. Now take that same senario and add a long sweaty workout. You'll probably pee a lot less because your body is using that water for sweat. I think the samething happens with protein. If you eat a lot of protein but don't workout, you are probably not going to absorb a lot. But it you eat a lot of protein and workout like a madman, you will probably absorb a lot more protein because your body needs it.

Be careful on relying on the color of urine to gauge hydration, especially if you take a multi
