Okay I need a bit of help I exercise like 6 days a week ( not sure if this matters) I do weights etc & cardio. My protein goal on here is set to 81 grams but I weigh 132lbs. Should I not be consuming 132 grams of protein? Anyway because it's set to 81 grams I'm always going over my goal by like 20/30 grams on some days. Could someone if they can tell me exactly how much protein I should really be taking in or does it really not matter? Don't be harsh guys!!!

If you are active and not sedentary or obese, then you only need 0.6 to 0.8 grams protein per 1 lb. bodyweight. This is the optimal range to maintain existing muscle and to promote new muscle synthesis.
So that would be 79 to 106 grams per day based on your current weight.0 -
I just want to know why MFP says I need something like 230 grams a day.0

Not sure.
Regardless, it's wrong.0 -

Agree. 81 is on the low end, but not 'too' low. If you go over by a few grams or more, it's not a big deal - provided it's not negatively impacting your other macro goals.0 -

I'm always fine with my other macros and staying under calorie goal but for like the past week I've been over my protein by 20/30 grams everyday .. Is this okay or not good?0 -
Based on the range sixxpoint posted above, you're probably fine.0

Okay thank you ... Is it true that protein is stored as fat if too much is consumed or is it used as energy? I heard that the liver struggles to cope with too much protein .. Not sure if that's true or not though0 -

Check your macro ratio. MFP may have a large portion of your daily calories coming from protein.0 -
Not sure.

MFP is neither wrong nor right to be honest. Protein consumption is one of those things that for a lack of better words, "optimal" is up-in-the-air. There are SSSSOOOO many studies that say anything from 1.4 gm's / kg of bodyweight for recreational resistance trained individuals, up to 2.3 gm's / kg, as high as 3gm's / kg (pre-contest bodybuilders), to a study that evaluated the effects of 4gm's / kg as excessive calories and the effect on weight gain. The one thing that I would say researchers know, and I use that loosely, is that above 2.2gm's / kg (~1gm / LB) is not useful unless you're a pre-contest bodybuilder and I think the quantity of those studies is limited at that. If the OP is 132lbs then that's approximately 59.6 kg's and at a protein multiplier of 1.4 gm's / kg, that's approximately 83.4 gm's of protein which is why I say MFP isn't necessarily wrong, because 1.4 gm's has show to be effective in some studies.
The best answer I can give you is to watch your progress in your strength training and adjust as you go. If you felt like jumping to 1 gram / LB of BW then do it and maybe that will be better for you. This subject is really tricky to discuss because there are studies that point every which way as to what's "best". I hope I didn't add any confusion to the matter. Cheers!0 -

Excess calories - regardless of whether they come from protein, dietary fats, carbs, alcohol, etc - will be stored as fat. Liver and/or even moreso kidneys can suffer damage from too much protein, but we're talking HUGE doses here, not a few extra grams.0 -

Incorrect.
The most current studies all echo the effectiveness of the range I provided, whether you are a bodybuilder, an athlete, or just someone who goes to the gym 4 times per week. The results are all the same; the only difference is the way the studies measure those results, e.g. lean body mass vs. bodyweight or kilograms vs. lbs.0 -

That isn't entirely true either. Above I mentioned that there was a study done where an excessive amount of protein was consumed, about 4 gm's / kg if I remember correctly, and the treatment group did not gain weight from the excessive calories derived from the protein consumption. Try and Google it if you're interested, but it had some interesting findings. I'm not sure if there are more out there. Additionally, to my knowledge at least, there are no studies showing negative affect on one's renal function in healthy individuals.0 -

Dude, check your math.
0.6 gm's / 1LB (low end of what you've read): 132lbs x 0.60 = 79.2
1.4 gm's / 1KG: 59.55kg's (132 lbs) x 1.4 = 83.4
Kinda' talking the same thing no? I just finished my MS degree, I promise that I'm speaking about current research too, our professors had very strict standards on what is current and what's not.

Ahh..yes.. Google. The "If it's on the internet it must be true" crowd's favorite source for scientific data.0 -

I don't recall, you'd have to find the study again. All I remember is that the calories were in excess to some degree. It was only the one study so it's definitely not absolute by any means, but it's an interesting suggestion on excessive calorie consumption.
And NO... it was found in my graduate school's library but you might find on the internet via Google located on PubMed or Google Scholar or XYZ web-site that provides peer reviewed studies. Nice try though...0 -

I don't need to check my math. I know I am accurate. Besides, comparing 79 vs. 83 grams is picking at straws.
Your suggested target is simply incorrect when you incorporate the combined results from all of these studies.
1 to 1.2 grams protein per 1 lb. lean body mass or 0.6 to 0.8 grams protein per 1 lb. bodyweight is what is typically suggested in these studies as optimal... They work out to roughly the same final protein goal.
Do they test ranges less or more than this? Of course, but they are not as effective.0 -

Here's the thing and this is what I learned while working on my MS degree, there are very few absolutes in research. You can only "bank" on the quantity of research that implies the same thing in the results and also, if those results are repeatable. I don't discount what you said, I believe there are studies that support exactly what you're saying. But what I'm saying is also accurate as we specifically studied protein consumption in one of my classes.
My point with my "math" comment is that you said 0.6 gm's / lbs was part of the "good" range, but it's almost exactly the same metric as 1.4 gm's / kg. The difference between the two is marginal.0 -
Depends what your calorie goal is and what your % protein goal is. You can change them. Do you know what yours are set to?sandrarinck wrote: »I just want to know why MFP says I need something like 230 grams a day.

I think if you would do some in-depth research on more than a couple pieces of research you would see what I'm saying. Unfortunately I've read close to 400 pieces of peer-reviewed literature in the last 18-months and I can tell you that the data is very very skewed, on most subjects at that.0 -

That's called a range, my friend.
Here is some research that should put your mind at ease about protein intake:
Tarnopolsky et al. (1992) observed no differences in whole body protein synthesis or indexes of lean body mass in strength athletes consuming either 0.64g/lb or 1.10g/lb over a 2 week period. Protein oxidation did increase in the high protein group, indicating a nutrient overload.
Walberg et al. (1988) found that 0.73g/lb was sufficient to maintain positive nitrogen balance in cutting weightlifters over a 7 day time period.
Tarnopolsky et al. (1988) found that only 0.37g/lb was required to maintain positive nitrogen balance in elite bodybuilders (over 5 years of experience, possible previous use of androgens) over a 10 day period. 0.45g/lb was sufficient to maintain lean body mass in bodybuilders over a 2 week period. The authors suggested that 0.55g/lb was sufficient for bodybuilders.
Lemon et al. (1992) found no differences in muscle mass or strength gains in novice bodybuilders consuming either 0.61g/lb or 1.19g/lb over a 4 week period. Based on nitrogen balance data, the authors recommended 0.75g/lb.
Hoffman et al. (2006) found no differences in body composition, strength or resting hormonal concentrations in strength athletes consuming either 0.77g/lb or >0.91g/lb over a 3 month period.

Regardless, it's wrong.
MFP is neither wrong nor right to be honest. Protein consumption is one of those things that for a lack of better words, "optimal" is up-in-the-air. There are SSSSOOOO many studies that say anything from 1.4 gm's / kg of bodyweight for recreational resistance trained individuals, up to 2.3 gm's / kg, as high as 3gm's / kg (pre-contest bodybuilders), to a study that evaluated the effects of 4gm's / kg as excessive calories and the effect on weight gain. The one thing that I would say researchers know, and I use that loosely, is that above 2.2gm's / kg (~1gm / LB) is not useful unless you're a pre-contest bodybuilder and I think the quantity of those studies is limited at that. If the OP is 132lbs then that's approximately 59.6 kg's and at a protein multiplier of 1.4 gm's / kg, that's approximately 83.4 gm's of protein.
Incorrect.
The most current studies all echo the effectiveness of the range I provided. The results are all the same; the only difference is the way the studies measure those results, e.g. lean body mass vs. bodyweight or kilograms vs. lbs.
Dude, check your math.
0.6 gm's / 1LB (low end of what you've read): 132lbs x 0.60 = 79.2
1.4 gm's / 1KG: 59.55kg's (132 lbs) x 1.4 = 83.4
Kinda' talking the same thing no? I just finished my MS degree, I promise that I'm speaking about current research too, our professors had very strict standards on what is current and what's not.
I don't need to check my math. I know I am accurate.
Your quoted target is simply incorrect when you incorporate the combined results from all of theses studies.
1 to 1.2 grams protein per 1 lb. lean body mass or 0.6 to 0.8 grams protein per 1 lb. bodyweight is what is typically echoed in these studies as optimal... They work out to roughly the same protein goal.
Do they test ranges less or more than this? Of course, but they are not as effective.
Here's the thing and this is what I learned while working on my MS degree, there are very few absolutes in research. You can only "bank" on the quantity of research that implies the same thing in the results and also, if those results are repeatable. I don't discount what you said, I believe there are studies that support exactly what you're saying. But what I'm saying is also accurate as we specifically studied protein consumption in one of my classes.
Good for you. That's why I gave a range based on 40 years of scientific research. I didn't throw out a single figure or a specific percentage to set your protein macro.
No, then what's this?0.6 to 0.8 grams protein per 1 lb. bodyweight.
Again, there's nothing wrong with that range. You're just using your findings as the absolute gospel of protein consumption and that is a very incorrect way of looking at it. I think if you would do some in-depth research on more than a couple pieces of research you would see what I'm saying. Unfortunately I've read close to 400 pieces of peer-reviewed literature in the last 18-months and I can tell you that the data is very very skewed, on most subjects at that.
That's called a range, my friend.
Here is some research that should put your mind at ease about protein intake:
Tarnopolsky et al. (1992) observed no differences in whole body protein synthesis or indexes of lean body mass in strength athletes consuming either 0.64g/lb or 1.10g/lb over a 2 week period. Protein oxidation did increase in the high protein group, indicating a nutrient overload.
Walberg et al. (1988) found that 0.73g/lb was sufficient to maintain positive nitrogen balance in cutting weightlifters over a 7 day time period.
Tarnopolsky et al. (1988) found that only 0.37g/lb was required to maintain positive nitrogen balance in elite bodybuilders (over 5 years of experience, possible previous use of androgens) over a 10 day period. 0.45g/lb was sufficient to maintain lean body mass in bodybuilders over a 2 week period. The authors suggested that 0.55g/lb was sufficient for bodybuilders.
Lemon et al. (1992) found no differences in muscle mass or strength gains in novice bodybuilders consuming either 0.61g/lb or 1.19g/lb over a 4 week period. Based on nitrogen balance data, the authors recommended 0.75g/lb.
Hoffman et al. (2006) found no differences in body composition, strength or resting hormonal concentrations in strength athletes consuming either 0.77g/lb or >0.91g/lb over a 3 month period.

That's awesome and you just proved my point. Look at some of the information you provided, and hopefully you're reading more than the abstracts, but there is a wide range of protein recommendations in there. Look at the Tarnopolsky reference, look how low those values are compared to the "range" you mentioned and even some of the values I mentioned; it's exactly what I'm talking about. Also, the ranges you're referring to in these references were measured in grams per pound, whereas I'm referring to grams per kilogram. I'm not arguing or disagreeing with you, I'm just saying there's no absolutes and you should see that in the references you provided.
Really, if you want current research you should keep it within the last 10 years unless it's something that was ground-breaking and 100% proven to be true. If you presented most of the above research to a professor they would fail you. In the case of protein consumption, there is no absolute and again; the references you provided above reflect just that. I'm not going to argue, I have a feeling you're stuck on something and being too dogmatic on this subject so I'm out.
@OP, make your best choices based on the information provided in this thread. When in doubt, go to a licensed dietitian.0 -

You really don't know how to read research, do you?
The average results of all of these studies suggest a range of 0.60 - 0.80 grams of protein per 1 lb. bodyweight.
Okay, I'll bite at that one... Yes I do, I have a Masters degree in Exercise Science; graduated with honors actually., wrote a meta-analysis too. You cannot average the results of multiple studies especially when the studies evaluate different populations; you cannot do that it is incorrect. If you want to take studies of just "power athletes" and take the average of that, then that would be reasonable. The OP isn't a Power Athlete, so the results of those studies are out-of-context to what the OP needs. The OP needs information related to recreational resistance training individuals, not bodybuilders, not powerlifters, not strength athletes, not power athletes; those results are pretty much out-of-context because they do not address the population represented by the OP of this thread. To get a more accurate protein recommendation for the OP, you would need to find a bulk of current (2005 to 2015) peer-reviewed research that discusses protein consumption for recreational resistance trained individuals within her age group. That is the only way to get an accurate conclusion for her. Just about anything else is out-of-context.0 -

Your quoted target is simply incorrect when you incorporate the combined results from all of theses studies.
1 to 1.2 grams protein per 1 lb. lean body mass or 0.6 to 0.8 grams protein per 1 lb. bodyweight is what is typically echoed in these studies as optimal... They work out to roughly the same protein goal.
Do they test ranges less or more than this? Of course, but they are not as effective.
Here's the thing and this is what I learned while working on my MS degree, there are very few absolutes in research. You can only "bank" on the quantity of research that implies the same thing in the results and also, if those results are repeatable. I don't discount what you said, I believe there are studies that support exactly what you're saying. But what I'm saying is also accurate as we specifically studied protein consumption in one of my classes.
Good for you. That's why I gave a range based on 40 years of scientific research. I didn't throw out a single figure or a specific percentage to set your protein macro.
No, then what's this?0.6 to 0.8 grams protein per 1 lb. bodyweight.
Again, there's nothing wrong with that range. You're just using your findings as the absolute gospel of protein consumption and that is a very incorrect way of looking at it. I think if you would do some in-depth research on more than a couple pieces of research you would see what I'm saying. Unfortunately I've read close to 400 pieces of peer-reviewed literature in the last 18-months and I can tell you that the data is very very skewed, on most subjects at that.
That's called a range, my friend.
Here is some research that should put your mind at ease about protein intake:
Tarnopolsky et al. (1992) observed no differences in whole body protein synthesis or indexes of lean body mass in strength athletes consuming either 0.64g/lb or 1.10g/lb over a 2 week period. Protein oxidation did increase in the high protein group, indicating a nutrient overload.
Walberg et al. (1988) found that 0.73g/lb was sufficient to maintain positive nitrogen balance in cutting weightlifters over a 7 day time period.
Tarnopolsky et al. (1988) found that only 0.37g/lb was required to maintain positive nitrogen balance in elite bodybuilders (over 5 years of experience, possible previous use of androgens) over a 10 day period. 0.45g/lb was sufficient to maintain lean body mass in bodybuilders over a 2 week period. The authors suggested that 0.55g/lb was sufficient for bodybuilders.
Lemon et al. (1992) found no differences in muscle mass or strength gains in novice bodybuilders consuming either 0.61g/lb or 1.19g/lb over a 4 week period. Based on nitrogen balance data, the authors recommended 0.75g/lb.
Hoffman et al. (2006) found no differences in body composition, strength or resting hormonal concentrations in strength athletes consuming either 0.77g/lb or >0.91g/lb over a 3 month period.

That's awesome and you just proved my point. Look at some of the information you provided, and hopefully you're reading more than the abstracts, but there is a wide range of protein recommendations in there. Look at the Tarnopolsky reference, look how low those values are compared to the "range" you mentioned and even some of the values I mentioned; it's exactly what I'm talking about. Also, the ranges you're referring to in these references were measured in grams per pound, whereas I'm referring to grams per kilogram. I'm not arguing or disagreeing with you, I'm just saying there's no absolutes and you should see that in the references you provided.
Really, if you want current research you should keep it within the last 10 years unless it's something that was ground-breaking and 100% proven to be true. If you presented most of the above research to a professor they would fail you. In the case of protein consumption, there is no absolute and again; the references you provided above reflect just that. I'm not going to argue, I have a feeling you're stuck on something and being too dogmatic on this subject so I'm out.
@OP, make your best choices based on the information provided in this thread. When in doubt, go to a licensed dietitian.
You really don't know how to read research, do you?
The average results of all of these studies suggest a range of 0.60 - 0.80 grams of protein per 1 lb. bodyweight.
Okay, I'll bite at that one... Yes I do, I have a Masters degree in Exercise Science; graduated with honors actually., wrote a meta-analysis too. You cannot average the results of multiple studies especially when the studies evaluate different populations; you cannot do that it is incorrect. If you want to take studies of just "power athletes" and take the average of that, then that would be reasonable. The OP isn't a Power Athlete, so the results of those studies are out-of-context to what the OP needs. The OP needs information related to recreational resistance training individuals, not bodybuilders, not powerlifters, not strength athletes, not power athletes; those results are pretty much out-of-context because they do not address the population represented by the OP of this thread. To get a more accurate protein recommendation for the OP, you would need to find a bulk of current (2005 to 2015) peer-reviewed research that discusses protein consumption for recreational resistance trained individuals within her age group. That is the only way to get an accurate conclusion for her. Just about anything else is out-of-context.
Good for you. You seem to be very proud about that yet you advise people to hire dieticians (lol) and you do not seem to understand how research works.
Our physiology and the way our bodies function does not vary greatly from person to person. What you are suggesting is that active individuals with different workout routines will require vastly different amounts of protein from each other. I hope you don't believe in gender-specific protein powder, too... but it seems like you probably do.
Sorry, but when it comes to nutrition, hormone health, new muscle synthesis, etc. you are not comparing an elephant to a human, a plant to a human, a worm to a human.... you are comparing humans to humans. It isn't as complicated as you're trying to make it.
Lastly, the results for optimal protein intake haven't really changed in the last 40 years. Even so, I did reference a study done in 2011 above... In that study, they determined that 0.80 grams of protein per 1 lb. bodyweight was the upper end of what can be utilized to promote new muscle synthesis, even in bodybuilders.0 -
in for the "debate"!0

Fair enough ...I'll retract my snark on the Google comment. Though I might respectfully suggest referring to Google Scholar, etc instead of just saying "Google it" (which you have to admit, is far too often used to justify outright false premises) in the future. The former I would have had a much different reaction to.
In the end though, in re: the OP - it seems we're all in about the same ballpark...so I'm not exactly sure what we're bickering about any more (other than it's MFP and that's what we do).0 -

because the +/-25g protein spread matters!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! It means I get one less serving of cereal.0 -

I'm not sure either. I never said he was wrong, I just there's no abolute because the available data lends to many different results. The only things I do know, not think, that's he wrong about is averaging results. Results must be applied in-context to the population that is studied, period. We can debate the human is a human all day long but there is a huge difference between the needs to an olympic weight lifting athlete and a recreational lifter.0
