too much protein?

My trainer told me to eat about half my weight in protein (g).....I'm not a doctor, and neither is she, but it seems to work for me.

Anything over 150 - 180g on a regular basis is probably going to put an excessive load on your kidneys. Plus, if your body can't use it, it will convert it into fat, even if you are within your maintenance calories.

I usually eat between 150-200g of protein per day. I've done this for the past year or so. No problems losing, no kidney problems either. I'm 5'9" currently 330 lbs.

I agree with eating a lot of protien, as stated above. My one caution is to watch out for supplements that give you too much protien at once. Your body can only process (depending on the person and metabolism) 8-15g / hour. So the "SUPER EXTRA PROTIEN SHAKE 68g OF PROTIEN" is a waste, you are not getting all of that protein. They are expensive and if you waste it you are paying a ton of money to poop out protein shakes.

I drink shakes everyday, and usually about 25-35g per shake.

Pretty sure that unless you're trying to go extremely low carb and high protein and low fat together, you're good to go. And even then, it might not hurt you.

Or so says wiki.

Since protein only contains 4 kcal/gram, and a typical adult human requires in excess of 2000 kcal to maintain the energy balance, it is possible to exceed the safe intake of protein if one is subjected to a high-protein diet with little or no fat or carbohydrates. However, given the lack of scientific data on the effects of high-protein diets, and the observed ability of the liver to compensate over a few days for a shift in protein intake, the US Food and Nutrition Board does not set a Tolerable Upper Limit nor upper Acceptable Macronutrient Distribution Range for protein.

Anything over 150 - 180g on a regular basis is probably going to put an excessive load on your kidneys. Plus, if your body can't use it, it will convert it into fat, even if you are within your maintenance calories.

Neither of these things are true. Please do not post misinformation as fact.

Joey, your protein is set quite low. Try to eat 1g of protein per 1lb of lean body mass. I have no idea how tall you are but as a male I'm guessing it's gonna be at least 150g a day. Best of luck.

I apologize if I was incorrect, but that is what my research revealed, and I wasn't posting it as fact. This is an open forum. The best you're going to get here for any question you post is an educated opinion. For fact, you should consult a nutritionist.

W-wha? You can't just absolve yourself of bad information by saying that it's "just your opinion" so "no harm done, facts don't exist here and you shouldn't expect them". So your research was based off of what? Other people's opinions or something else besides facts? If I understand you, the only people that can state facts are professionals in a given field? If I state that Venus is the second planet from the sun, that is just my opinion and not a fact, because I'm not an astronomer? What if a nutritionist is on one these open forums? Is there some sort of paradox where any information they dispense is rendered factually neutral because it is a forum (wherein there can be no facts) but they are harbingers of facts themselves?

Oh, and no - you don't have to worry about too much protein under normal circumstances.
