    GGDaddy, Thanks for the info. That sounds pretty consistent with the lean gains I've read about. Interesting info.

    Glad to contribute to a good thread. Thanks for the summary of the Lyle study.

    I agree with SideSteel. And not only that, but I feel great when I eat ~25% protein. Less than 15 or 20%, and I feel like I have less strength. More than 30% and digestion can get uncomfortable depending on the type of protein. I also read a study that showed that people not exercising but eating a carefully controlled surplus gained the same amount of muscle on both 15% and 26% protein. But less than 15% and most of the weight gain was fat (however they also gained less weight). So that tells you something. And personally I think more than 35% protein or so might be overkill in general. (Too much might even cause or worsen existing kidney/liver issues.) I eat according to MFP and it works well most of the time for me, personally.

    DRINK WATER. Healthy or not kidneys dealing with more than 30% of your daily calories in protein get unhappy, and when they get unhappy you get stones, and when you get stones you regress to being 2 complete with the crying. Do not get stones it is not a good look.

    Protein intake related to kidney stones? Never heard of that. Can you give more info?

    When you metabolize proteins you throw off uric acid, which is excreted by your kidneys, when your urine PH drops the uric acid can make stones as it falls out of suspension or it pushes the calcium oxalate out of suspension. These collect and make kidney stones, and give you an unhappy face.

    Forgot the reference

    Interesting. It appears it can contribute, but probably only of you're prone to them already.

    This link discusses the above study as well as others.

    If you are peeing at least 2 liters it all sort of become moot. Real the problems mount when get chronic dehydration plus Atkins and then you get major stones, and remember that was only a 6 week study.

    I am not saying that not to eat large amounts of protein, just to make sure you are drinking more water. As they suggest in the stone section of your piece there may be underlying quirks of metabolism that may be exacerbated with excess protein.

    Percentages are silly.
