Calculate Your Recommended Protein Intake
Metrics details. Controversy exists about the maximum amount of protein that can be utilized for lean tissue-building purposes in a single meal for those involved in regimented resistance training.
However, these findings are specific to the provision of fast-digesting proteins without the addition of other macronutrients. Consumption of slower-acting protein sources, particularly when consumed in combination with other macronutrients, would delay absorption and thus conceivably enhance the utilization of the constituent amino acids. The purpose of this paper was twofold: 1 to objectively review the literature in an effort to determine an upper anabolic threshold for per-meal protein intake; 2 draw relevant conclusions based on the current data so as to elucidate guidelines for per-meal daily protein distribution to optimize lean tissue accretion.
Both acute and long-term studies on the topic were evaluated and their findings placed into context with respect to per-meal utilization of protein and the associated implications to distribution of protein feedings across the course of a day.
Based on the current evidence, we conclude that to maximize anabolism one should consume protein at a target intake of 0. Using the upper daily intake of 2.
A long-held misperception in the lay public is that there is a limit to how much protein can be absorbed by the body. Based on this definition, the amount of protein that can be absorbed is virtually unlimited. Following digestion of a protein source, the constituent amino acids AA are transported through the enterocytes at the intestinal wall, enter the hepatic portal circulation, and the AA that are not utilized directly by the liver, then enter the bloodstream, after which almost all the AA ingested become available for use by tissues.
While absorption is not a limiting factor with respect to whole proteins, there may be issues with consumption of individual free-form AA in this regard. Specifically, evidence shows the potential for competition at the intestinal wall, with AA that are present in the highest concentrations absorbed at the expense of those that are less concentrated [ 1 ]. The purpose of this paper is twofold: 1 to objectively review the literature in an effort to determine an upper anabolic threshold for per-meal protein intake; 2 draw relevant conclusions based on the current data so as to elucidate guidelines for per-meal daily protein distribution to optimize lean tissue accretion.
These results extended similar findings by Moore et al. Although the findings of Areta et al. In addition, individual variables such as age, training status, and the amount of lean body mass also impact muscle-building outcomes. A major limitation in the study by Areta et al. This is far below the amount necessary to maximize muscle protein balance in resistance-trained individuals who served as participants in the study [ 6 , 7 ].
Furthermore, the ecological validity of this work is limited since habitual protein intakes of individuals focused on muscle gain or retention habitually consume approximately 2—4 times this amount per day [ 8 , 9 ].
It also should be noted that subjects in Areta et al. While the rapid availability of AA will tend to spike MPS, earlier research examining whole body protein kinetics showed that concomitant oxidation of some of the AA may result in a lower net protein balance when compared to a protein source that is absorbed at a slower rate [ 10 ].
An important caveat is that these findings are specific to whole body protein balance; the extent to which this reflects skeletal muscle protein balance remains unclear.
Although some studies have shown similar effects of fast and slow proteins on net muscle protein balance [ 11 ] and fractional synthetic rate [ 12 , 13 , 14 ], other studies have demonstrated a greater anabolic effect of whey compared to more slowly digested sources both at rest [ 15 , 16 ], and after resistance exercise [ 16 , 17 ].
Compounding these equivocal findings, research examining the fate of intrinsically labeled whey and casein consumed within milk found a greater incorporation of casein into skeletal muscle [ 19 ]. The latter finding should be viewed with the caveat that although protein turnover in the leg is assumed to be mostly reflective of skeletal muscle, it is also possible that non-muscle tissues might also contribute.
Interestingly, the presence versus absence of milk fat coingested with micellar casein did not delay the rate of protein-derived circulating amino acid availability or myofibrillar protein synthesis [ 20 ].
Furthermore, the coingestion of carbohydrate with casein delayed digestion and absorption, but still did not impact muscle protein accretion compared to a protein-only condition [ 21 ].
More recently, Macnaughton et al. The researchers speculated that the large amount of muscle mass activated from the total body RT bout necessitated a greater demand for AA that was met by a higher exogenous protein consumption.
It should be noted that findings by McNaughton et al. Given that muscular development is a function of the dynamic balance between MPS and muscle protein breakdown MPB , both of these variables must be considered in any discussion on dietary protein dosage. Kim et al. Results showed that the higher protein intake promoted a significantly greater whole-body anabolic response, which was primarily attributed to a greater attenuation of protein breakdown.
Given that participants ate large, mixed meals as whole foods containing not only protein, but carbohydrates and dietary fats as well, it is logical to speculate that this delayed digestion and absorption of AAs compared to liquid consumption of isolated protein sources. This, in turn, would have caused a slower release of AA into circulation and hence may have contributed to dose-dependent differences in the anabolic response to protein intake.
A notable limitation of the study is that measures of protein balance were taken at the whole-body level and thus not muscle-specific. It therefore can be speculated that some if not much of anti-catabolic benefits associated with higher protein intake was from tissues other than muscle, likely the gut. Even so, protein turnover in the gut potentially provides an avenue whereby accumulated amino acids can be released into the systemic circulation to be used for MPS, conceivably enhancing anabolic potential [ 25 ].
This hypothesis remains speculative and warrants further investigation. It would be tempting to attribute these marked reductions in proteolysis to higher insulin responses considering the inclusion of a generous amount of carbohydrate in the meals consumed. Although insulin is often considered an anabolic hormone, its primary role in muscle protein balance is related to anti-catabolic effects [ 26 ].
Although the previously discussed studies offer insight into how much protein the body can utilize in a given feeding, acute anabolic responses are not necessarily associated with long-term muscular gains [ 30 ]. Wilborn et al. Similarly, a lack of between-group differences in lean mass gain was found by Fabre et al.
In a day study of elderly women, Arnal et al. A follow-up study by the same lab in young women reported similar effects of pulse versus spread patterns of protein intake [ 34 ]. The combined findings of these studies indicate that muscle mass is not negatively affected by consuming the majority of daily protein as a large bolus.
However, neither study employed regimented resistance training thereby limiting generalizability to individuals involved in intense exercise programs. Insights into the effects of protein dosage can also be gleaned from studies on intermittent fasting IF.
A recent systematic review concluded that IF has similar effects on fat-free mass compared with continuous eating protocols [ 35 ]. However, the studies reviewed in the analysis generally involved suboptimal protein intakes consumed as part of a low-energy diet without a resistance training component, again limiting the ability to extrapolate findings to resistance-trained individuals.
Helping to fill this literature gap is an 8-week trial by Tinsley et al. Perhaps most interestingly, biceps brachii and rectus femoris cross sectional area showed similar increases in both groups despite the h fasting cycles and concentrated feeding cycles in TRF, suggesting that the utilization of protein intake in the ad libitum 4-h feeding cycles was not hampered by an acute ceiling of anabolism.
Unfortunately, protein and energy were not equated in this study. Subsequently, an 8-week trial by Moro et al. These findings further call into question the concern for breaching a certain threshold of protein intake per meal for the goal of muscle retention.
In contrast to the above findings showing neutral-to-positive effects of a temporally concentrated meal intake, Arciero et al.
During the initial day eucaloric phase, HP3 and HP6 consumed protein at 2. HP6 was the only goup that significantly gained lean mass.
During the subsequent day eucaloric phase, HP3 and HP6 consumed protein at 1. HP6 maintained its lean mass gain, outperforming the other 2 treatments in this respect HP actually showed a significant loss of lean mass compared to the control. In any case, it is notable that comparisons in this vein specifically geared toward the goal of muscle gain, hypercaloric comparisons in particular, are lacking.
An important distinction needs to be made between acute meal challenges comparing different protein amounts including serial feedings in the acute phase following resistance training and chronic meal feedings comparing different protein distributions through the day, over the course of several weeks or months. Longitudinal studies examining body composition have not consistently corroborated the results of acute studies examining muscle protein flux.
Quantifying a maximum amount of protein per meal that can be utilized for muscle anabolism has been a challenging pursuit due to the multitude of variables open for investigation.
Perhaps the most comprehensive synthesis of findings in this area has been done by Morton et al. This was based on the addition of two standard deviations to their finding that 0.
In line with this hypothesis, Moore et al. Importantly, these estimates are based on the sole provision of a rapidly digesting protein source that would conceivably increase potential for oxidation of AA when consumed in larger boluses. It seems logical that a slower-acting protein source, particularly when consumed in combination with other macronutrients, would delay absorption and thus enhance the utilization of the constituent AA.
However, the practical implications of this phenomenon remain speculative and questionable [ 21 ]. The collective body of evidence indicates that total daily protein intake for the goal of maximizing resistance training-induced gains in muscle mass and strength is approximately 1. However, 1. Bandegan et al. This reinforces the practical need to individualize dietary programming, and remain open to exceeding estimated averages.
It is therefore a relatively simple and elegant solution to consume protein at a target intake of 0. Using the upper CI daily intake of 2. This tactic would apply what is currently known to maximize acute anabolic responses as well as chronic anabolic adaptations. Further research is nevertheless needed to quantify a specific upper threshold for per-meal protein intake.

How Much Protein Do You Need to Build Muscle?
Depending on whether you are active or sedentary, underweight or overweight, the amount of protein your body needs for optimal health varies. As you can see in the chart above, for every 1 pound of body weight you need But why the range? However, there is evidence that shows when in a caloric surplus, more calories from protein results in less fat gained than if those excessive calories were from carbohydrates or fats [ 2 ][ 3 ]. A common myth is that eating too much protein in one sitting is wasted.
Protein is a key nutrient for gaining muscle strength and size, losing fat, and smashing hunger. Use this calculator to find out how much protein you need to transform your body or maintain your size. Protein is essential for life. It provides the building blocks for your body's tissues, organs, hormones, and enzymes. This macronutrient is crucial for building and maintaining muscle mass.
Protein Intake – How Much Protein Should You Eat Per Day?
How much protein per day do you need to build muscle? Eating large amounts of protein can be expensive, as well as impractical. So, with all that in mind, how much protein should you eat if you want to maximize muscle growth? After crunching the numbers, they came to the conclusion that eating more than 1. To calculate the amount of protein you need to maximize muscle growth, multiply your bodyweight in pounds by 0. If you prefer metric, multiply your bodyweight in kilograms by 1. In other words, they think that the muscle-building benefits of protein plateau at around 0. But, they acknowledge that there may be a small benefit to eating more — around 1 gram per pound of bodyweight per day, or 2.
How Much Protein Do You Need to Maximize Muscle Growth? A No-Nonsense Look at the Science
Few nutrients are as important as protein. If you don't get enough through your diet, your health and body composition suffer. It turns out that the right amount of protein for any one individual depends on many factors, including their activity level, age, muscle mass, physique goals and current state of health. This article takes a look at optimal amounts of protein and how lifestyle factors like weight loss, muscle building and activity levels factor in.
We may all laugh at the gym rat who's surgically attached to his protein shake bottle, but that doesn't alter the fact that protein and muscle go hand-in-hand. That's because the muscle-building macro contains amino acids, the building blocks used for muscle growth, but exactly how much do you need to consume daily to keep building bulk? Protein guidelines generally fall into one of two camps; a proportion either of how much you eat, or how much you weigh.
