It won’t make you bulk up (it’s really hard for women to bulk up no matter what we do unless we have extra testosterone) but it isn’t good for your kidneys.

You’d need to go over by a lot more than that to really affect your kidneys.  I will have to google to make sure, but I think the average person should get about .9g of protein per kg of body weight, and people who are really active should get 1.8g/kg body weight, and weightlifters even more, but if you get wayyyyy too much you increase your risk of kidney stones.  I’ll double check the numbers because nutrition class was a long long time ago 🙂

You’ll probably know you need to back down if you suddenly get constipated. A lot of protein will start stopping you up, usually.

I agree with DaneLady, you’d have to have about 4 or 5 times that amount before you worry about your kidneys being affected. My trainer told me that i should have about a gram of protein for every pound that you weigh.

Well, technically yes, but the number is so astronomically high that you likely won’t get it with a normal diet.

MFP goals are set way low on protein.  A healthy aspiration is to hit 1 gram of protein for every pound of your goal weight (so if your goal weight is 125, you should aim for 125 g of protein).  That’s the high end, but it’s still healthy.  Your body can’t process more than 30-40 grams of proten per meal though, so keep that in mind!

I eat around 120g of protein a day. I make sure to get plenty of fiber so that I don’t get stopped up because it happened when I first switched to a high protein diet. Not fun…

I don’t think it’s too much of a problem as long as your ratio’s over time CHO:PRO:FAT (55:15:30) are consistent with the recommended amount and you aren’t having any symptoms.

You will notice if your body thinks you are getting too much protein. You will have painful gas bubbles (aka abdominal cramping), constipation, etc.

Here are a few links for you… the first one includes the mathematical calculations, the second summarizes how much protein you should eat.  I think at 90g of protein as long as you’re not going way over your total calories you should be ok.  You can always check your local grocery store to see if they employ a nutritionist or ask your primary care doctor to refer you to a dietician and make sure that you are on the right track 🙂

From the link just above: “Your protein requirements depend on your total caloric intake. Protein should make up 10 to 35 percent of your daily calories. For someone on a 2,000-calorie diet, this translates to between 50 and 175 g of protein every day. A person consuming 1,600 calories each day needs between 40 and 140 g of protein every day.”

From what I’ve read, a high protein diet could affect kidneys already in trouble- it won’t negatively impact healthy kidneys.

If you are going to regularly eat a lot of protein (I try to get around 90 g per day) make SURE you are drinking lots and lots of water.

@Tatum:  Yeah that’s probably what I was thinking.  I have a history of kidney stones so have been told not to let the protein intake get too high but others could probably go higher.

Agree with other posters about needing fiber with a high protein diet or things could get uncomfortable.
