Most Protein Shakes Are More Then 20g Of Protein Some Go Up To As Much As 80g Of Protein Or More. Is it true that your body will only process up only 20g of protein per an hour and the reamaining protein is peed out or sweated out? what happens to the rest of the protein?

As far as I know, that's not true. :)

I know that excessive protein is passed through urine, but I'm not sure what exactly those levels are or at what rate our body's metabolize it.

Protein losses in the urine and sweat are relatively low. An athlete may lose 3 grams/day in the urine and 1 gram/L of sweat that is released from the body.

There is no set rate. Some people digest more, some less. It's also relative to what you are used to. If you typically consume 15 grams in one setting and suddenly consume 80 grams, chances are you're not going to have a good go at ingesting them. If you gradually increase amounts, however, you may end up digesting most, if not all.

The problem is that the assumption is usually that if you digest 80 grams, 80 grams is going towards building your muscle tissue. It's not.

All of that extra protein will simply be deaminated. This means the nitrogen molecule will be stripped off to form a skeleton that can be converted to glucose. Then it is just burned as energy or converted and stored as fat.

You really don't need more than about 0.8 - 1.0 times your bodyweight in pounds of protein per day. So if you weigh 200 pounds, that's 200 grams of protein on the top end. If you're eating 6 meals, that's about 30 - 35 grams of protein per meal. Personally I've never had a need to go above 100 grams of protein per day, and I still have guns that outmatch most casual gym goers.

The only beef I have (pardon the pun) is that protein is the most expensive macronutrient, so if your calories are restricted, why not splurge them on energy the way your body needs it and supply just the protein it needs to recover and build new tissue? No need to go extreme to amounts like 80 grams.

The argument I've heard to weigh the macros more toward the protein side even if you don't need it for building muscle tissue is this: Protein breakdown to a usable form in the body is more "expensive" metabolically, so it ups the metabolism and provides a thermogenic effect just by having the protein vs something like like a high GI carb. So even if it's used only for gluconeogenesis (converted to blood glucose), it's upped the metabolism a bit in the process.

Not saying this is the end all. Obviously there are plenty of other ways to do it. I just don't think high protein diets (where you consume more protein than you actually need) are necessarily wrong or wasteful.

I understand the argument. However, the fact that it has a thermic effect is true and I often use it for fat loss ... however, the fact is, you are forcing the body to do something it is less efficient at. While a healthy adult probably won't have any issues due to the extra load, why would I want to put an extra strain on my body and kidneys when I don't have to? That's my point.

I know plenty of people who have done fine with prolonged high protein diets. Personally I don't feel good on them and was elated to find I don't even need them ... I can raise my metaobolism just as much through consuming fiber, healthy fats, and activity.
