Weight-Loss
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!! =)

protein absorption - too much?
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.
"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.

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.
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.

protein shakes
here's a question that I will pose. In the late summer/fall I was trying to eat a lot of protein, i was doing some weight training, i was "running" on an elliptical 5-6 days a week, and eating normal meals, protein at lunch and dinner, w/ 2 protein shakes a day. i just seemed to be ballooning up, and not musclemass, i felt like i was getting chubbier, does that make sense or was i just going about it all wrong?

If you were truly gaining fat, you were most likely eating too many calories per day.

When I upped my protein, that was ALL that went up. Carbs maybe went up by 2-3 more carbs/day but almost the exact same besides 3 extra chicken breasts and another scoop of whey (which is ALL protein).
Normally when people up their protein that normally get more carbs and fat along with it, which is something you need to pay mind to.

If you eat more than you can use of any macronutrient, it is converted to fat.
If Im not mistaken the RDA for protein is .8g/lb.

with some people it can effect your kidneys in a bad way. my husbands friend had to cut back on the protien b/c of that.
Do the raw amino acids themselves have calories that can be converted to fat?
I don't know this for a fact by any means, but I have always thought that kidney damage wasn't necessarily caused by the protein itself, but other byproducts of meat, and also a lack of carbs.
When you don't eat enough carbs, you body will try to burn protein as an energy source, which makes byproducts that are hard on your kidneys. I have always assumed that if you eat enough complex carbs to allow your body to fuel off of, that protein won't be burned as an energy source, and therefore kidney damage is at least minimized.
Also, alot of people who eat alot of protein will eat alot of meat, and the byproducts of the meat, including the animal's lactic acid, will be absorbed into the bloodstream, putting a big load on the kidneys. Supposedly these byproducts can even be absorbed through the colon walls and get back into your bloodstream.
Both of these issues were discussed in the Mountain Bike Training Bible. So, this is why I've always assumed that excess amino acids ALONE isn't necessarily harmful, just not needed. I think it's the other extra baggate that does damage.
Amino acids is protein.
Yeah, I know, but I was just trying to clarify the question. I mean that protein in its rawest form... not protein powder, not chicken, not steak, just pure protein, the amino acids themselves and NOTHING else... would it have calories? Would branched chain amino acid supplements have calories that could be turned into fat? Just curious.
