Is there such a thing as to much protein? I am averaging around 100g/day. My trainer thinks this may be a reason that I am not losing weight. I am curious if anyone else has ever had this problem. I am working out daily and my body composition is changing, but I worry because I am not losing any weight at all.

Yes, too much protein can be a bad thing for your kidneys - if you're not drinking enough water. If you're lifting weights and not seeing weight loss, try keeping track of body measurements. You may be replacing fat with muscle.

100 grams is definitely not too much. I agree that as you are exercising your body is changing and may hold on to some weight; drink your water, switch up your caloric intake and I bet you will see the scale move again.

I aim for a minimum of 100 grams but I am also very tall. Without the proper amount of protein your muscles can break down and that is a big concern with me.

Most guys looking to build muscle mass are eating 1g of Protein per pound of lean body weight. You are no where close to eating to much. I am actually a little worried that your trainer would tell you 100g is to much protein. That protein is preserving your muscles.

Do you want to lose weight faster at the expense that the weight lost is actually muscle?

I eat over 100g a day and notice I am losing huge amounts on a measuring tape, doing decent in actual weight numbers but I lift 5 days a week and cardio 7 days. I am 7 weeks out and have stalled 3 times but the weight catches up. Once I am close to goal I plan to up my daily protein intake to around 200g daily.

Just make sure you are spacing out your protein intake... its to much protein if your drinking 100g in 1 hour.

Are you getting enough Water. The minimum 64oz is really not a lot if your exercising. I ate over 120g of protein and 120oz of water every day for 3 days and it broke my last stall... dropped 5lbs over night.

To my knowledge, there has never been a successful study showing any detrimental effects on the kidney. People have tried but failed to link high Protein diets with kidney toxicity or other issues. Most of the time, too much protein (rare) in the diet just leads to a good crap the next day, which is wasted money, but no harm physically. As long as you're getting a good quality protein, most should be absorbed as long as you're working out. If your trainer is saying you're getting too much protein at 100g/day, I'd ask to see another trainer. Ask for his certifications. If he doesn't have any nutritionist training and only entry level physical certs, he's absolutely in no position to comment on your nutrition. There have been studies showing as high as 243% protein consumption with no ill effects. The food and Nutrition Board states there is not evidence of any issues coming from high intakes of protein, not saying someone couldn't have issues, just saying in general studies, it shouldn't be a concern for someone trying to lose weight and gain muscle at this point, especially if only consuming 100g of protein.

How long have you been working out like this? I have another long post somewhere regarding Water weight and how water weight is stored and such after workouts. It's important to take days off from time to time to let your body recoup and recover as well. You're likely not over training, but it's just good mentally and physically to take a break every once in a while.

I'm not an expert, but I think too much protein can cause gout, I would ask your Nut to be safe. Don't take our word for it. Best of luck!

So whats the max amount of protien per day for a women pre menopausal?

No one can say how much per person, some try, but they won't be exact. The general rule, find lean body mass, and then get .8g to 1g per that number. You need to supply the muscle with Protein, the fat really doesn't care if it gets protein or not. Some days you could get more, some days you could get less, but that's the ballpark idea of things.

Use this calculator to find a rough estimate of your lean body mass. It's best if you actually can get the number through calipers, if you're using a trainer they should be able to do this, or order skin fold calipers online and follow the instructions to get closer numbers. Some scales can get "decent" ballpark numbers for you. http://www.bodybuilding.com/fun/lbm_calculator.htm

For protein intake, there are so many schools of thoughts. I've worked with clients and friends who believe .5 is the magic number, and I've worked with some who believe Dr. Lemons theory of protein overload. He would recommend me, weighing 316lbs right now, to get nearly 600g protein a day. That's crazy/

Ok.. lmao I juat needed that in English terms thanks. But I'll just ask my Nut

It's not complicated. Your body weight, either multiply that by .80 and that's your protein intake. Or, just use the common 1/1, if your bodyweight is 150, 150 grams is your intake. If you want to get more technical, go to the link I gave, and enter your information. Then, use that as your amount of protein intake per day.

100g is definitely not too much Protein. I would say don't drink/eat more than 30g at a time.

yes but like many things the factors are dependent on many variables. Protein has calories per just like everything else.

This is the breakdown

Fat: 1 gram = 9 calories

Protein: 1 gram = 4 calories

Carbohydrates: 1 gram = 4 calories

Alcohol: 1 gram = 7 calories

My bariatric surgeon did not want me to go over 65. He had a cow when I told him that I was shooting for the 85-100 mark. He said that was too much for me. I'm 5'3 and in my thirties. I do increase my Protein tho over 100+ on days that I run or get in a good workout. Not a nutritional expert or anything, nor do I claim that this is right. It's my experience only. I think it's good to ask around, but be prepared for varied answers.

Mark- are you suggesting I would take 180 * .80 = 134 grams a day? Is this number with regards to an active lifestyle or to an inactive lifestyle? I currently am eating about 125 grams a day on average and also run 3-4x a week and cross fit 3 days a week I am not lifting very heavy in cross fit, but expect this to change as my lifting ability improves. I noticed that even when eating 125 grams a day without any lifting, but with running, my muscles atrophied quite a bit, especially in arms. Thanks for any advice. I am learning as I go.

It depends, with me, on what kind of Protein I'm taking at that time. I've gotten some Proteins from a few sponsors that I felt I couldn't get in my normal amount. I don't personally follow the 1/1 ratio of grams of protein/bodyweight. When I was in the 340's and 350's competing, I stuck to about 250g to 325g protein per day, with as much coming from bison, beef or chicken as I could get in.

If you're feeling like you're hitting atrophy, you could most your protein numbers around a bit. Usually on lifting days, my protein intake is way higher for obvious reasons. Are you running hard say, a day after lifting? It could be fatigue in the muscle heads causing that feeling, I've noticed I cannot even think about running after squat day or my calves and hamstrings will be screaming 10 minutes in to my cardio. Are you taking any creatine on lifting days or any recovery things? I mix creapure with my protein, and glutamine, it helps with recovery quite a bit. You could always adjust your macro-nutrients around to get 150g protein a see if that helps the feeling and recovery. For each individual it takes some tweaking of the numbers to get the right amount of protein, just depending on how you lift and run, and how your body is.
