I don't have a direct source, but I do know that studies have indicated that over-consuming protein can cause calcium loss (well, above-average calcium loss) in the urine. For that to happen, about 35% of your diet would have to be protein, and that's assuming you eat enough anyways. I personally probably consume close to 100g of protein a day (on the 6 days that I train), if I were to consume 150g, that's probably where I would start to see problems (bare in mind, I'm not a big guy). Also, in an indirect link, many people who try to be "healthy" forgo dairy, personally, I don't eat much either, but you also have to make sure you get enough from other sources (multi-vitamens, veges, and so on) alot of people don't do that.

Avoid too much protein. Getting too much protein can leach calcium from your bones. As your body digests protein, it releases acids into the bloodstream, which the body neutralizes by drawing calcium from the bones. Animal protein seems to cause more of this calcium leaching than vegetable protein does.(3) Just how important protein is as a risk factor for osteoporosis is still up in the air.

It should be noted that acid (Acid in the proton donor sense) is formed when the body METABOLIZES the protein, not just breaks it down. It will break it down to use the amino acids for the trillions of functions we need them for, but when you get too much, it gets metabolized, like sugar, fat, even nucleic acids (which also produce acid, although unless any of you are seriously under-nourished, I wouldn't worry about it). So some people need 40g of protein a day, some 150g, neither of them will leach calcium from their bones (not an appreciable amount anyway). Now if the guy who should have 40g, has 150g a day, he can expect a lot of broken hips come retirement.

P.S. Good link Punchdrunk, people should read that over, atheltes often overlook the importance of getting enough minerals and vits, and focus on carbs and protein and lack of fat.Comment

aren't you supposed to be having a gram of protein per lb of bodyweight?? or is it kg?Comment

Well that rule goes by kg, and it's a very general ruleComment

You guys are ridiculous with this too much protien stuff, he didnt say he was consuming like 300 g of protien each day, you should take like .8 g of protien for each pound you weigh, you should be fine, you do that and work out you should build muscle quicker than usual.Comment

Ok, really that rule is general as ****. There's a huge difference between a 160lb fatass and say Bernard Hopkins. Do you think they took in the same protein (or at least should have been). B.Bomber, from what I've read you train (or at least have been trainin') hard, so 120g is fine. The only thing is that when you take it a lot more than you need, you metabolize more, which through a long sequence of events, takes the calcium out of your bones. Personally, I'm 155, and take in about 110g of protein daily, but that's just me, hell, ask me, tell me what you do, and I'll do my best to tell you what you should be having, but I'm not doctor or nutrionist. Just know that any real athlete should be a little more specific than some "I weight this, so I'll eat this" rule. In the end though, as an athlete, it's probably better to go over than under. Not so good for your bones later, but if you're gonna go hard till your 30, and then lay off, you're not gonna doom yourself to a life of week bones, and your body will be getting the amino acids it needs.
