Just curious as to what the limit should be. Is it all about your individual size or is there a "critical" amount that is considered unsafe for human consumption, despite size and weight?
Thanks,
Julienne

Juli, you would probably gain a lot of weight before hitting your upper protein limit. You know about the 1 to 1 1/2 grams of protein per pound of bodyweight I'm sure. are you trying to exceed that?

I believe I read somewhere on this site that whatever protien your body doesn't use gets turned into fats, like any other excess caloires.
So its just like anything else you eat.

No, I do know that, but I read an article that disturbed me because it made it sound as if too much protein could be detrimental to your health. So, I started wondering if there were people out there that took it to a whole different level...or if there was such a thing.
I think the article was actually aimed at low carbers and basically stated that eating too much protein could cause you to become sick, keep your body from working properly and even prevent conception in females. It seemed extreme to me so I thought I would ask if that had any validity.
Maybe it was just poorly written.

Actually I believe un used protein does not get stored as fat but washed away in the urine.

dfly411 everything in excess is bad for your health and yes, unused protein become into fat. protein is energy
nonused energy becomes fat. althou you should know that protein is not only for muscle use. your body needs it for its own functioning. extra proteins are used in order for you to leave.
as far as i have read, a high protein diet it good for your health. an excess protein intake might have some benefit to those interested in changing body composition and decreasing cardiovascular disease risks.
and as charlie said, are you trying to exceed the 1gm of protein per kg?
i don't think you have to worry about ir very much.
correct me if i am wrong

You know I have never heard of excess protein turning into fat....do you have a study that you got that info from? For the most part according to what I have learned unused protein is flushed out fo your body via the kidneys.....maybe I am wrong....

I have herd it is flushed out threw kidneys as well, however it is turned into urea, wich in large amounts can damage the kidneys, but most peopel on here drink plenty of water, so that shouldn't be a problem. But if you eat too much, your literally just pissing money away.

I got the following from Bodybuilding.com
*******************************************
Protein is one of the most important substances we consume. After this article you will know how much protein your body needs. The function it plays in survival, the way it is processed and used.
Other than water, protein is the most abundant nutrient in the body. Protein is a chain of linked units called amino acids. The protein you eat is split apart into these amino acids, absorbed in the small intestines, then rearranged and put back in the blood stream. These new arranged proteins carry out specific functions to maintain life. All living tissues are made up of twenty-two essential and nonessential amino acids. Essential amino acids are not made by the body and must be supplied through diet. There are nine essential amino acids: Histidine, Isoleucine, Leucine, Lysine, Methionine, Phenylalanine, Threonine, Tryptophan, and Valine. The remaining thirteen are nonessential amino acids produced in the body and not essential to consume through the diet.
Twenty two in all. Amino acids are divided into 2 groups:
Essential Non-essential
Histidine Alanine
Isoleucine Arginine
Leucine Aspartic Acid
Lysine Cysteine
Methionine Cystine
Phenylalanine Glutamic Acid
Tryptophan Glutamine
Threonine Glycine
Valine Hydroxyproline
Proline
Serine
Tyrosine
Protein provides four calories per gram. The human body can do three things with protein calories; put protein in fat stores, use it as an energy source or use it to carry out functions vital to life. Protein calories will be used as an energy source when the body is lacking fat or carbohydrate calories for fuel. When the body receives sufficient quantities of proteins, fats and carbohydrates, protein will carry out its specific functions. These proteins functions include: replacement of old cells, building muscles, organs, blood, nails, hair, skin, and tissues. Protein also takes part in hormone, antibodies, and enzyme formation.
Fasting your body without proper protein intake will cause your body to slowly start shutting down. You must not only eat enough protein, but you must eat the right types. Without the right amount of essential proteins, no matter how much you eat, your body will waste the protein and not run properly.
A diet that is low in essential amino acids does not carry out all of its protein functions. Protein follows the all-or-none law: inadequate amounts of essential amino acids cause the body to excrete proteins in urine as urea. The remainder of the protein is converted to glucose, fat, or metabolized for energy. This lack of essential amino acids prevents proteins from performing their normal functions. Foods that have all nine of the essential amino acids are called complete proteins. Complete proteins include all food from animal products, milk, cheese, chicken, beef, and ext. Don't worry folks! Proteins that are incomplete (plant products) can be combined with complementary proteins that carry the missing amino acids to form a complete protein. Examples of incomplete protein are grains, cereals, and vegetables. To complement these proteins you would combine beans with grains, or nuts with cereal.
Now that you have an understanding of the right kinds of protein to eat, we will discuss how many grams you need to eat.
In Understanding Normal and Clinical Nutrition, the Authors say, "The Committee on Dietary Allowances of the Food Nutrition Board of the National Academy of Sciences states the RDA in grams of protein per kilogram of body weight per day" (Whitney 153). If calories are sufficient in carbohydrates and fat, You divide your body weight by 2.2, this gives your weight in kilograms. You multiply your kilogram weight by 0.8, this gives you your daily intake of protein. A person who weighs 95 kilograms (210 pounds), would take 95 kilograms times 0.8. Their daily protein intake would work out to be around 77 grams, 12% of your calories would come from protein.
We do know that long bouts of exercising increases the need for nutrients, especially protein. In Nutrition For Fitness and Sport with Powerweb the author says, " a number of studies involving endurance athletes found that 0.97-1.37 grams of protein per kilogram per day were needed" (Williams 112).

BB.com was the first mistake. If you follow the guidelines of protein in this article, you will never gain an ounce of muscle. A hard training resistance athlete needs way more protein than 12% of daily calories.
The second number is closer, but still may well be way off. And they are emphasizing for endurance athletes, not resistance athletes which makes even less sense. Many clinical dieticians with tons of degrees still fail or don't want to recognize the needs of resistance athlete. Think about it, if you are going through catabolism on a daily basis, which we are training, how in the world will a mere 12% of calories come close to retaining the muscle you do have, let alone build new muscle. The trouble with bodybuilding.com is they allow anything to be put up on their site if it sounds like it has some knowlege behind it. There is much bad info going on over there. Be careful what you read.

Boy, how did I miss this post! Excess protein can and will be converted to glycogen if needed first and foremost. The only way protein will be converted to fat in any manor is if maintenance calories are met, and glycogen stores are full. Even then with the breakdown of amino acids, it is more than likely expelled from the body. There is a chance of some spillover, but think of this....
Fats are the most ketogenic item since only 10% can be converted to glucose. Proteins convert to glucose with 58% efficiency. Carbohydrates convert to blood sugar with 100% efficiency. So, it is highly unlikely that proteins will be stored as fat. It is always better to err on the high side of protein than too low.

Everyone appreciates it too anni313. I was simply giving a warning about some of the things out there. There is so much misinformation that is regurgitated over and over by folks that don't know any better, some actually well meaning. We are glad you are with us and willing to do some legwork. Shows you have some drive.:big_smile:

I am not regurgitating - excess intake, when not used by the body will lead to storage. Whil protein is less likely to be stored as fat, it can be. Anyhow, not here to argue...
Dfly - here is some stuff on protein intake:
" There has been considerable debate regarding the protein needs of athletes. Initially it was recommended that athletes do not need to ingest more than the RDA for protein (i.e., 0.8 10 1.0g/kg/day for children, adolescents, and adults). However, research over the last decade has indicated that athletes engaged in intense training need to ingest 1.5 - 2 times the RDA of protein in their diet (1.5 - 2.0g/kg/day) to maintain protein balance.
If an insufficient amount of protein is obtained from the diet, an athlete will maintain a negative nitrogen balance which can increase protein catabolism and slow recovery.Over time this may lead to lean muscle wasting and training intolerance." Sports Supplements, Jose Antonio, PHD, CSCS and Jeffrey R. Stout, PHD, CSCS
" During training and competition, endurance athletes need about .75grams of protein per pound of bodyweight per day - 1.2 to 1.4/kg of bodyweight - to maintain a positive nitrogen balance and to promote muscle recovery and growth." "Chad Coy..research and development director for Human Development Technologies and is ranked among the top strong men. His ideal diet follows these guidelines:...Protein should make up 30 to 40 percent of the total calories." "The football player's preseason diet follows the same distribution of macro-nutrients as the strongman's year-round training diet...Protein 40-45 percent of calories, or 1.5grams per pound of bodyweight" Diets designed fro Athletes, Maryann Karinch
"Recent studies using metabolic-tracer and nitrogen-balance technologies have shown that the overall protein and specific amino acid requirements are higher for individuals in training than for normaly active people. The role of protein differs for endurance and stregth training athletes. it appears that strength training individuals need up to 1.5 to 2.25 times the RDa, or 1.4 to 1.8g of protein per kg of bodyweight, whereas endurance athletes need 1.2 to 1.4g of protein per kg of bodyweight. Whereas endurance exercise places greater demand on protein as an auxiliary fuel, strength training requires additional amino acids as the building blocks for muscle development.
Studies of college men revealed that those who engaged in a month of weight training and followed diets containing either 0.8g or 2.4g of protein per kg of bodyweight each day retained more protein than a group of men who followed the same diet but did not train....Only the group on the higher-protein diet significantly increased fat-free body mass." Physiology of Sports and Exercise, Jack H. Wilmore & David L. Costill (this is one of my college textbooks).

Asimmer, I think you may have read more into my reply than was there. You are exactly correct, and incorrect also if that makes sense. If you notice the first line of my reply is "If maintenance calories are met, and glycogen stores are full, protein can well be converted to fat"...this is due to excess calories. Excess calories of any type have the ability to be stored as fat, but not all are. If this was the case, imagine how much fatter we would be!! It is like in a perfect world, if all protein was used for muscle, we would all be giant and muscular. The key here is the word excess as in calories. The problem lies in the fact that to build muscle, you need to exceed maintenance calories(calorie surplus), so it is a double edged sword so to speak. But while excess protein can be converted to fat, it is not as likely to be as excess carbs for instance. I hope all this rambling clears things up a bit.

Oh, and one more thing asimmer, I also was not referring to you in my statement about regurgitated material. I was referring to many of the posts and articles on other sites that sound like some kind of fact that folks read and thouroughly believe, so they pass it on over and over as fact in full honesty alot of times.
