I'm 6.1 feet, weigh about 165lbs and try workout everyday as well as weight training every other. Iv been taking whey protein and I try to keep my meals as high in protein as possible. But I'm beginning to wonder, how much protein is too much? Iv heard that over loading your body with exess protein can lead to kidney problems. Appreciate any feedback!

hey Jeremiah, great question. Usually eat between 1-1.2 g of protein per lb of body weight you have. That's a good range!0

My understanding is high protein, is good to keep your metabolism burning, as long as you drink a lot of water your kidneys should be fine, like 4 litters a day.0

Well I'm a lap band patient that was told you can never have too much protein. The problem with a lot of diets comes when people start taking out the proteins because they don't want the added calories. But they need to realize that a lot of people start having hair loss and brittle/fragile nails because they're lacking in protein. I try to ALWAYS go over by at least 10 on my protein intake, just because I don't want hair loss. (Plus, I also take a B complex supplement, and Biotin along with my multivitamins)
The only big side effect if you're not used to a high protein diet is ... well.... very raunchy bodily emissions. Once your body gets used to the protein intake, that starts to go away.0 -
You really only need about 1g-1.6g/kg bodyweight of protein a day. Maximum safe recommendation is about 2g/kg bodyweight each day. As you and I weigh the same that comes to about 75kg (165lbs) x 1 = 75g or 1.6 x 75 = 120g. So you only need between 75-120g a day of protein for maximum muscle benefits and no more than 150g protein to be on the safe side0

how many ounces would that be per lb? sorry I suck at math unfortunately!0 -
Crystalpauls's advice on protein is what I have heard. I might suggest however if you are consuming that much protein that you get it from a variety of sources; not all beef and protein shakes. Take Cod for example, nearly pure protein with very little fat. Salmon has beneficial fat. It cost a bit more but you have to eat fish every day and you don't have to eat loads of it.0

I have no idea, but if you are 6'1" and weigh 165 and are trying to lose 20 lbs...that's REALLY thin. For a medium frame, you are right smack in the middle of the range. Just make sure your goals are healthy. I'm also 6'1", and female, and I would need to be on IV fluids if I were 145. I know everyone is different and you may have a very slight frame, but just keep it healthy. :flowerforyou:

Well according to the study 'Protein Requirements and Supplementation in Strength Sports' in the Journal of Nutrition which looked at strength trained athletes and people doing resistance training in general they concluded that most people take excess protein. The more you use weights the more efficiently you use protein and therefore the less you actually need. However, as you gain muscle and get stronger you need more naturally as your caloric intake requirements increase.
At the end of the day though they came to the conclusion that the amount of protein you need and your efficiency in utilising it means you only need about 15% of your calories from protein. So even if you want to go higher than this and eat 20% protein you will still not need anymore than around 100-120g protein a day0 -
First of all, the kidney thing is a myth. IF you already have bad kidneys for some other reason, then eating more protein may strain them. But saying protein causes kidney problems is like saying that strenuous exercise causes heart failure. Well, yes, it can, but only if the organ is weak & damaged to start with.
Second, I don't know how much is too much, or whether there even is such a thing as too much. But I do know that my doctor's instructions to me are: eat at least 50g protein every 3 hours (I have a metabolism that doesn't process carbs well so I have to get most of my energy from fat & protein). That adds up to at least 350g a day, and it hasn't hurt me a bit. My doctor introduced me to several patients with similar problems who have sustained this high level of protein for a dozen or more years with no negative side effects. So I certainly wouldn't worry about it being unsafe. Just worry about whether it's right for YOU. Everyone's body is different, there is no "one-size-fits-all" recommendation. If the protein at current levels is helping you, go with it.0 -

Nutrients are always given in g or mg because an oz is just too large a unit.
1 - 1.2 mg of protein is about .03 to .04 oz but you'll have a hard time finding any food that lists protein in oz.0 -

Yes, but a 4 oz steak is not 4 oz of protein. Only about 30 percent or so of it is protein. Probably around 30 or 40 grams of protein in a 4 oz sirloin which is about 115 grams. If you look at the actual nutritional value of the steak itself, the protein content will be given in grams.0 -
Most Americans eat more than enough protein. One side effect of excessive protein intake is Ketosis, leading to ketoacidosis. This can be very serious. You may notice a change in the smell of your breath...more of an acetone smell. This is one sign of ketosis. Please consult your doctor or a registered dietitian if you want the real science behind high protein diets.0

There is nothing wrong with ketosis; that's a widely-circulated myth. Ketoacidosis and ketosis are two different things that are often confused.
My doctor has told me that I should try to keep myself in ketosis at all times. I have been in ketosis for over four months now with no ill effects, and I've met people who have been on this diet for over a decade and are just fine. A ketogenic diet has been successfully used to treat epilepsy, diabetes, hyperinsulinemia, depression and even migraines.
