??? about protein for you guys!

[MenTaLPiRacY]

ok.. here is what i want to know.. how many grams of protein does the human body process in an hour. the thing is ive been double stacking my protein and wondering if it is all going thru or is it in useless cuz the human body can only process so much at one time.. ok thanks.

That all depends on how extreme a workout u had, how big u are, what ur testosterone levels are.

For example, If u take steroids, ur Protein utilization and synthesis are increased, so your body can utilize much larger amounts of protein for muscle building.


I don't take steroids though.

Any excess protein will be converted by your liver into glucose for energy.


personally with food and supplements i usually never have more than 60-80 grams a protein within 1 hour. But normally i eat 30-40 grams of protein every 2 1/2 hours

[meathead198]

Timing of protein is quite unimportant, although make sure you get plenty around a workout.

Shoot for 1g per lb of BW every day. Dont worry too much about when you get it, just get it.

[DeadlyDan]

Well it does matter when you take it, because if u consume a lot in just 2 meals a day, that extra protein might be converted into glucose/fat.

[meathead198]

Not nessecarily. New research is showing meal frequency is not as important as was first thought.

[DeadlyDan]

wow really,? wrong, it is important.

What would be the point of eating dinner than 20 minutes later having another dinner?

Your body utilize nutrients better if u spread it out.

Also your body does well before a workout if u get around 30 grams of protein 1 hour before workout, also 6-10 grams of protein like minutes before u start working out.

Also, Right after u workout your GLUTAMINe levels are low, and replenishing them immediately though food/supplements is important.


They have released dozens of books on food timing. Though i have not seen a book with a title " food timing, it's a myth!"

[meathead198]

Sorry, I should have phrased that protein frequency. Meal frequency may be important, but the time you eat protein is not that important.

[MenTaLPiRacY]

ok thanks guys

You know what guys i hear two complete different sides to wether or not protein has a max absorbtion in one time. I hear that the body can digest unlimited amounts then i hear it can only take in so much differing from your weight. What i do to be safe is to stay medium low (40 grams) per serving. Although post workout I try to take in an extra 20 grams plus a large amounts of carbs. The extra protein will help getting my muscles into an anabolic (muscle building) state and the carbs will up my insulin levels for transport the protein to my muscles. this combo puts your muscles in a very rich enviroment to grow in. It has lots of proteins and sugars and your muscles will like that very much after a workout.

one gram of protein per bweight is to maintain
1.5 to gain

???? there is a lot of data available from the lab of Robert Wolfe and Esmarck showing that ingestion of portein/amino acids directly after exercise is more effective ...

And you should always try to minimize a drop in amino acid availability in the blood. Thus this means that you have to eat a certain amount of protein every 2-4h. the goal should be 1g/pund of body weight

[Big Cat]

This is all way too simplistic to offer an answer. First of all circumstances determine how much amino acids can be used and processed at any given time. A body that is in caloric deficit and under heavy strain can process a lot more amino acids than a freshly fed and well rested body. I'm assuming everyone can follow me on that. So it all depends on the demand your body has for amino acids at that point. If not used for processes of protein synthesis, some amino acids can be used as fuel, but this only occurs if there is a lack of energy from carbs.

Second thing to take into account is the digestion. If you take in 100 grams of whey, that hit your system in a half an hour, chances are less likely that you will be able to use it all than if you ingest 100 grams of casein that slowly digest and dissipate into your system over a period of up to 6 hours. Chances you can use all of this is a lot greater since the time-span is 10 times larger.

Keep in mind that our body is constantly breaking down and building up. That means the larger you are in actual tissue (protein) the more demand your body has for amino acids to keep its mass.

So circumstance, type of protein, state of digestive system, size and activity level all play roles in this. So if anyone says you can only process X amount, then they are bull****ting you. The amount you actually use can be quite large. Especially since in almost all cases it does get digested and absorbed and usually doesn't leave the body as fast as it entered, making it likely it can be used at a later time through renal reabsorption and what have you not.

contradictory to meathead and adding to bigtoms post, your body has no means for storing protein other than muscle catabolism. therefore i feel the timing of your protein consumption is very important.

Thats not true. I dont know what science site or book you read that from. Depending on your body type is determined by how much protein one needs. If your an endo 1g per lb is the min. If your an ecto than shoot for 1.5.

To maintain, eat maint cals, go gain eat above. Protein is important, but not all you need to grow.

You need more total calories to gain, not protein.
I believe that if you are cutting you need more protein to make up for the loss of calories due to cutting carbs.

I weigh 235 and shoot for 450g of protein when bulking, and 550g or so when cutting.

I think big cats post sums up the rest.

Unless you are on cycle, I see no reason to get 550g protein per day.

Unless youre a big mother f***** anything over 1.5g of protein per lb of body weight is going to end up in the toilet...the body can only process so much protein and the rest is shat out

Not entirely true; after the protein has been digested (ie hydrolysed to amino acids and absorbed in the gut) any amino acids that aren't assimilated are deaminated and converted to glucose to be stored as glycogen or fatty acids - amino acids are too precious for the body to be shat out.

As for the amount of protein the body can assimilate per hour/day, this would depend on your size, general fitness and health, remembering that muscles are not the only tissues in the human body made of protein (that is, blood components - red cells, immunoglobulins, blood factors; most hormones; hair, skin, nails, tendons and connective tissue; etc.)

Not to be overly critical, but anything that has been absorbed in the gut will not be shat out. Once its in the blood, it can only be pissed out ...

As well as current state, energy balance, other foodstuffs consumed, and when looking at the whole day, especially digestion rate. Because you all seem so ardent to discuss protein per hour, when a lot of proteins simply aren't completely digested in an hour, and some, like casein, can take up to 6 hours. So if you had a functional need for 20 grams of protein per hour, then you could be consuming 10-15 grams of whey every 30 to 45 mins, or you could be consuming 100-120 grams of casein every 5-6 hours. THese numbers are arbitrary by the way, just to make a point.
