How many grams of protein can you ingest

[Firehawk]

No need to get offended. We are only stating opinions here dude. By the way, I don't think you'd cause damage to your kidneys in this amount of time. It probably takes years of abuse, just like it takes years of smoking or drinking to ruin your organs.

Sorry, all my cash is going out too quickly these days to offer prizes for making me learn. I'm made to learn every day. If I paid for that...I'd be even broker than I am.

I could help with that at no charge if you weren't so far away. I'm getting pretty good with the acrylic kits.

Where do you get this idea you need 500 grams of protein? Science cannot be denied with regards to how much protein the body can process at one time. You can't store an extra 50 grams of protein (let's say you just dumped 100 grams in) without those 50 extra grams doing 2 things: Taxing your kidneys & organs, and going to fat. There's no where else for it to go, you don't have a holding tank.[/quote]


hey if we using the method 1-1.5 g of protien per pound of lean body mass, then we have to assume hes 300-400 lbs lean muscle mass.... lets give this guy a break

not trying to be mean just joking... actually I was totally with you guys til fmac did reply...if it works for him, then it works, and a guy I work with who goes to school for nutritional education tells me that it could destroy your kidneys, much like how overdrinking could destroy your liver, but thats part of theyre jobs, these organs were created for combating toxins, and also after a while you can increase the amount of protien you absorb... like with whey shakes, he told me that you absorb like 25%, but doesnt mean that if you keep drinking it daily, for a year or so, you could possibly absorb more of it, if not aalmost all of it........ the body learns to adapt?...... This is not a direct quote. besides me myself....... I would never take in over 250 grams of protien a day, 300 tops, if I wasnt keeping track..... caz Im not perfect with keeping track of what I eat, I just eat!

West, I'm with you,...and my eating style tends to be high/er in protein & fat as a baseline. You are exactly right, the body can only process so many grams of protein in one sitting, and any extra goes to fat (and yep, it severely taxes your kidneys and poisons your system).

In the defense (quasi) of the people taking massive amounts of protein (ie: 500 grams), they are probably taking 50 grams 10 times a day. But that not only seems very challenging to do, but it would be the only way to break it down. Even then,...the body cannot digest it all quick enough to make that workable....and even 50 grams taken at once is larger than the average "storage tank."

This is one of those things where (my humble little opinion only, mind you) I think that doing protein supplementation at that high of a rate on a consistent basis will catch up to the person doing it, eventually. And because the effects aren't felt or noticed right away, it can be carried on for a dangerously long time.

Like vitamins and minerals, the principle of "if some is good, more is better," it just doesn't work that way.

YOU CANNOT, because they don't exist. UNLESS you have a PRE-EXISTING LIVER OR KIDNEY DISORDER, YOU CAN'T PHYSICALLY CONSUME ENOUGH PROTEIN TO CAUSE PROBLEMS.

Most advanced lifter eat 2 grams or more per lb of bodyweight, and not lean bodyweight--BODYWEIGHT. And there are no health issues involved. I have personally looked at lab results of 100's of lifters eating 2 grams a lb and liver and kidney values are normal. ALT and AST may be elevated, but that is from the LIFTING. Yes, just lifting heavy elevates these numbers.

Please don't come to this board and talk trash you know nothing about so you can justify your porridge and toast habit.

I predict you will be one of the guys that soon quits lifting because "it doesn't work for you". You cannot build a house without the materials to do so, nor can you build over average musculature without a LOT of protein. This has been known fact for about 50 years.

Wes posted this on his board recently in response to someone who was basically stating what's been stated in this thread "high protein is bad, it will kill your kidneys, etc", and I have to say, it makes sense.

I went and searched pubmed myself and could not find anything that scientifically proved that extreme protein is detrimental to your health.

250g a day is a bit ridiculous. The body only can process like 120

[cursor]

What can be processed by "the" body will vary substantially from person to person. Depending on what one does (or doesn't do), the amounts of protein, carbohydrates, and dietary fat will vary dramatically. As physical stress grows, tissue turnover increases. Without argument, I think all can agree that 1) a regular long distance runner, 2) a serious powerlifter/weightlifter, and 3) a Melrose Place couch potato will all require varying amounts (and balances) of primary macronutrients. No?

What about body size?
What about lean mass volume?
What about workout intensity?
What about workout regularity (physical stress frequency)?

Protein requirements are NOT the same for everyone. Can anyone seriously argue otherwise?

they had an article about this in FLEX a while back...

pretty much said that being able to digest only 40grams of protein per meal was full of BS and that your body will adjust to eating high amounts of protein...assuming your working out and etc...

also for every pound of muscle you gain your resting metabolic rate increases 3%...so your gonna need more food

like a while back i remember jay cutler talking about working up to eventually be able to consume 1000 grams (yes one thousand) of carbs in a day...yes it sounds insane for the average person who sits a desk all day...and i understand he is a professional and that is his job to work out but still...my point is you can train your body to do anything

The body will process whatever you put into it with the exception of some nondigestable fiber. This includes protein, it will process EVERY gram. Now the question is...what does it do with it? Well, that answer is pretty simple. It uses what it needs for muscle synthesis and muscle repair. Then...what does it do? Goes through the process called glucogenesis - conversion to glucose. That's right, excess protein becomes carbohydrate in the simplest form of sugar there is. Then if the blood glucose is elevated, it is stored as glycogen. If the glycogen stores are full...then it is stored as body fat. But it will be used in some way by the body.

So to say, "the body can't process it" is absolute BS. Perhaps to say "the body doesn't need it" would be more accurate. And no, it is not harmful to healthy kidneys or liver. Can you consume too much? Sure you can. Will it harm your organs? Nope. Will it make you fat? Absolutely. But then...so will excess of anything you eat.
