So I am watching TV, and I hear the mention of 'protein poisoning'. I googled it and it seems to be a bad thing, lol. And I've been eating alot of lean meats in my new diet. So has anyone heard of this protein poisoning thing? This is a first for me. Anything to be concerned about here?

Nutrition is my very serious hobby, I guess I shoulda put that in my hobbies list! I kind of obsess about it, and not being much of a meat eater (I'm a fish & vegetarian kind of girl) I've still read a lot about this. You should only worry if you have bad kidneys, but otherwise not really. Are you drinking enough water? That's crucial for anyone on a fairly high protein diet. Are you lifting weights? That'll be helpful to make most efficient use of it too. As long as you're not on the "all meat" diet, don't worry. Get some healthy whole grains and veggies in there and your colon and kidneys will cope with the lean meat just fine. Don't skimp on the water though or you'll get super constipated!

for a woman, about 50-60 grams of protein is enough. for a man, its slightly higher. of course this will vary according to your activity level and weight. protein cannot be stored in the body and any excess protein consumed that is not needed will just be excreted. also, the more protein you consume the more B6 vitamin and calcium your body will require to metabolize the protein. too much protein over an extended period of time can put a lot of stress on your kidneys. drinking plenty of water is very important!

That's a good rule of thumb too wonderwoman. You're absolutely right. I once saw a protein requirement calculator based on lean body mass. I wish I knew where that was.

So, Mr. "ImaFatass", moderation is always a good rule. You will excrete whatever you eat that's in excess of what you can use (except in the case of fat-soluable vitamins), and that's where the healthy kidneys and water come in. "Protein poisoning" refers to a buildup of the byproducts of protein digestion in the bloodstream - one reason you need plenty of fiber and water in the higher protein diet. If your kidneys are in good working order, you should be able to clean out the blood before it becomes a problem, but don't go overboard, too many calories are still too many calories, and you still need the high fiber grains & veggies for proper digestion. Including more protein requires that you include more fiber to help get rid of what you don't need, and in the case of the ammonia & ketones, what you don't want. So, including lean meat in your diet is good, but make sure what you eat is also nutritionally varied. If you like meat, more power to ya, but I hope you also like broccoli!

WOW, I'm very impressed!
Not a lot of people know this about protien! With all the high protein, low carb diets people don't realize we don't need THAT MUCH protein, it's hard on your kidneys, you're right, it can lead to dehydration.
You normally would need several years of being on these high protein diets inorder to see the negative effects...but I think the worst effect is NOT getting enough CARBS!
Carbs are our main source of energy NOT proteins.

I'm loving this forum already!! =)

This quote below made me think of a question that I've had below:

"It was mentioned that I might need up to 140g of protein a day - I managed to get 100+ once last week."


I hear similar things alot. I've heard of guys who aren't exactly elite eating around 200 grams of protein, and they recommend doing the same. Yet at the same time I read studies that show that people don't need near as much protein as they think. I've even seen where Arnold himself said that even elite athletes in training only need 120 grams. Even Bicycling magazine recently published an article that said that a realistic rate for fit athletes is only absorbing 4 to 5 grams of protein per hour. If this is true, then think about it... alot of this protein consumption makes no sense.

Now, according to a PowerBar article, apparently protein absorption rates can spike as high as 10 grams per hour if you consume whey protein. But, you're not going to eat whey protein all day long either!

So, my question, is that why do I see alot of people saying PROTEIN PROTEIN PROTEIN, when your body cannot aborb it, and it's just flushed down the toilet? And, if this isn't the case, then why are there studies saying otherwise? Here's just one that barely hints on it, I've seen others.


PowerBar: Nutrition Resource Center

"Over a 24-hour period, 6-7 grams of protein per hour corresponds to a maximum protein intake of about 144-168 grams of protein per day. So here again, there isn’t support for the 250 or more grams of protein per day favored by some strength athletes."


Maybe some people really are only consuming 20 grams a day or something, I don't know.

I've personally seen a study where it showed that up to 23g of whey could be digested/hour.

Most elite strength athletes who eat 300g+ of protein/day, are on some 'chemical enhancement' lol..

hello

Just curious, what happens if you eat too much protein each day and then what is too much.
just wondering thats all

In a study by Lemon et. al., they found that 1.8g/kg of bodyweight was required for positive nitrogen balance. However, Forslund et. al. found that if you jumped up the number to 2.5g/kg, you not only had a positive protein balance but you had a negative fat balance (you burned more fat as an energy source).

For those of you that don't know...divide your weight by 2.2, this gives you your kg in weight.

With the protein itself, I think all that happens is that you pee it out if your body can't use it. At least that's kind of what the Mountain Bike Training Bible says. But, I imagine it depends on what you're eating to get that protein. If you're stuck on eating 200 grams a day and getting it from tuna and eggs, then your daily intake of mercury and cholesterol is probably sky high which could lead to other problems.


I guess I'm trying to figure out the same thing. Apparently it depends on who you ask. One "expert" will say hardly anybody is eating enough, while another "expert" will say that most people eat more than enough, even athletes in training.

I have adjusted my diet many-a times over the years, and I find 200g a day is when I make the most gains. I notice no difference over 200, and I do notice a slowing in my progression. The only way to tell is go balls to the walls for a few months, and adjust the diet and see what works.

Agreed with Mreik... it will be different for everyone. I think 1 gram per pound is a good measure, unless one is carrying a lot of fat on their body. If that is the case, 1 gram per lb of LBM is probably better suited. But again, you are going to have to toy with the numbers.

And when dieting (read caloric deficit), protein requirements actually go up.

ETA: 1 gram per lbs is a recommendation assuming what is moderately active and resistance training.
