Do You REALLY Need Lots of Protein To Build Muscle?
Summary
TLDRThis video explores the necessity of protein for muscle gains, challenging the common belief that high protein intake is essential. It reviews studies, including a 2022 systematic review by Tagawa et al., which found that while protein intake correlates with lean mass gains, the effect plateaus after 1.3 grams per kilogram of bodyweight. The video suggests that even at lower protein intakes, muscle growth is possible, especially for beginners and those in resistance training. It emphasizes the importance of regular resistance training over protein intake levels, encouraging viewers to pursue their fitness goals regardless of protein consumption.

Q & A
What is the general recommendation for daily protein intake for muscle building?
-Experts often recommend getting about 1.6 or more grams of protein per kilogram of bodyweight per day for muscle building.
Why might it be challenging for some individuals to meet the recommended protein intake?
-It can be challenging due to digestive issues and financial constraints, as many gym-goers may need to purchase protein supplements to reach higher levels of protein.
What does the research suggest about the impact of consuming less protein than the recommended amount on muscle gains?
-Research indicates that eating less protein leads to less muscle gain, but the extent varies widely from one study to another.
What did Tagawa and colleagues find in their 2022 systematic review regarding protein intake and lean mass gains?
-They observed that for every 0.1 grams of protein per kilogram added to the diet, lean mass gains increase by 0.39 kilograms until 1.3 grams per kilogram, after which the increase is only 0.12 kilograms.
What was the focus of Morton and colleagues' 2018 systematic review?
-They investigated the dose-response relationship between protein intake and lean mass in healthy young adults participating in resistance training.
How do the findings from the 2018 and 2022 reviews compare in terms of muscle gains and protein intake?
-When adjusted for weight changes, the trends from both reviews are quite similar, showing that muscle can be built at lower protein intakes but with less efficiency.
What is the significance of protein intake for older individuals in terms of muscle maintenance?
-Older individuals generally require more protein to prevent muscle loss, but they tend to respond less to higher protein intakes when combined with resistance training.
What is the importance of protein intake during a cutting phase for bodybuilders?
-During a cutting phase, more protein is crucial to preserve muscle mass and improve fat loss, along with resistance training.
How do beginners typically respond to resistance training in terms of muscle growth and protein intake?
-Beginners respond well to resistance training early on, even at lower protein intakes, giving them some time to adjust their protein intake.
What protein intake recommendation did the 2018 review suggest for trained individuals to maximize muscle growth?
-The review recommended as much as 2.2 grams of protein per kilogram of bodyweight per day for those wanting to maximize growth, but 1.6 grams should be sufficient for most.
What is the key takeaway message from the video regarding protein intake and muscle building?
-The key takeaway is that while less protein intake leads to less muscle building, it is still possible to build muscle. Regular resistance training is essential, and striving for adequate protein intake can enhance results.

đȘ Protein Intake and Muscle Gain
This paragraph discusses the importance of protein for muscle building, questioning the necessity of high protein intake. It mentions that experts recommend 1.6 grams of protein per kilogram of bodyweight daily, but this may not be feasible for everyone. The paragraph introduces research that suggests less protein intake can still lead to muscle gains, albeit at a reduced rate. A 2022 systematic review by Tagawa et al. is highlighted, which analyzed 66 studies to find a dose-response relationship between protein intake and lean mass gains. The review indicates that up to 1.3 grams of protein per kilogram, each additional 0.1 grams leads to a 0.39 kg increase in lean mass, beyond which the increase is only 0.12 kg. The paragraph also notes variability in responses due to different factors and the importance of considering individual circumstances.

Highlights
Protein is often touted as essential for muscle growth, but this video questions whether it's truly indispensable for muscle gains.
The recommended dietary allowance for protein to build muscle is 1.6 grams per kilogram of bodyweight per day.
The feasibility of meeting high protein intake can be challenging due to digestive and financial constraints.
Research suggests that less protein intake leads to less muscle gain, but the extent varies significantly.
A 2022 systematic review analyzed 66 studies to understand the relationship between protein intake and lean mass gains.
For every 0.1 grams of protein per kilogram added to the diet, lean mass gains increase by 0.39 kilograms, up to 1.3 grams per kilogram.
After 1.3 grams per kilogram, the increase in lean mass gains drops to 0.12 kilograms per additional 0.1 grams.
The 2022 review is unique for providing a visual and statistical insight into the protein-lean mass relationship.
A 2018 systematic review focused on healthy young adults and resistance training, showing similar trends in protein-lean mass relationship.
Muscle building is possible at lower protein intakes, but the gains are less pronounced.
Older individuals may require more protein to prevent muscle loss but show less response to higher protein intakes during resistance training.
When cutting weight, higher protein intake is crucial alongside resistance training to preserve muscle and improve fat loss.
Beginners can respond well to resistance training even at lower protein intakes, giving them time to adjust their protein intake.
Trained individuals benefit most from higher protein intakes, with a recommendation of up to 2.2 grams per kilogram of bodyweight per day.
The video emphasizes that muscle can still be built with less protein, as long as resistance training is regular.
The video concludes by encouraging viewers not to be discouraged by not meeting the 'optimal' protein levels, as 'close enough' can still yield good results.
Transcripts
Protein protein protein. Everyone loooves telling us how important protein is for our muscles.Â
Some even made it into a slogan! Can you believe that?Â
But, in this video, weâre going to find out if it really is THAT important or can Â
you still get all the good muscle gains without the protein gains.Â
When it comes to building muscle, experts often recommend getting about 1.6 or more grams of Â
protein per kilogram of bodyweight per day. However, this is not exactly feasible for Â
everyone, both digestively and even financially since many gym-goers Â
require purchasing protein supplements to reach these higher levels of protein.Â
So if we do eat less than what is considered optimal, what can we really expect to happen?Â
Looking through the research, one thingâs for sure is that eating less protein does Â
lead to less gains, but in terms of how much, it varies wildly from one study to the next.Â
Which makes sense if we think about it. Protein, as important as it may be, is really only one Â
factor among many factors in the fitness equation. So to deal with this variability, itâs probably Â
best to go over research reviews evaluating all the relevant data and Â
condensing for us into more practical insights. One of which is a 2022 systematic review, Â
where Tagawa and colleagues analyzed 66 relevant studies to evaluate a dose-response relationship Â
between protein intake and lean mass gains. In the findings, based on an average intervention Â
period of 20 weeks, they observed that for every 0.1 grams of protein per kilogram added to your Â
diet, lean mass gains go up by 0.39 kilograms until you reach 1.3 grams of protein per kilogram, Â
where then it goes up by only 0.12 kilograms. This review is one of the few if not the only Â
research that extrapolated the data this way, giving us a visual and statistical Â
insight on the relationship between lean mass gains and protein intakes.Â
I do wanna point out, though, that there was a wide range of subject populations included Â
in this review. And although they did adjust for some factors like age, sex, and training, Â
there are many other factors to consider. Perhaps a more relevant dataset for people Â
watching this video is from a 2018 systematic review, where Morton and Â
colleagues investigated similar outcomes but narrowed their scope to healthy young Â
adults participating in resistance training. Although they did not evaluate the specific Â
effect sizes, they did produce their own figure showing the magnitude of the dose-response Â
relationship of protein intake and lean mass. And when we compare this figure to the figure Â
from the previous review, the trends arenât all that much different.Â
In fact, when the 2022 data is further adjusted for weight changes, Â
since a lot of its data came from weight loss studies, they become even more similar.Â
If thereâs only one thing you take away from this video, it should be these figures:Â
Both show that you can build muscle at lower protein intakes but notably less the less protein Â
you eat. But if you gradually increase your protein, then you can further enhance your growth.Â
A few more tidbits worth mentioning: Older people generally require more Â
protein to stave off muscle loss, but they tend to respond the least with higher protein Â
intakes when paired with resistance training. If youâre cutting, more protein is important, Â
as is resistance training, to preserve your muscles and improve fat loss.Â
Beginners respond really well to resistance training early on, Â
even at lower protein intakes. So, if youâre new, you do have some time to figure out your protein.Â
In the 2018 review, the researchers found that trained individuals responded the best with Â
higher protein intakes, recommending as much as 2.2 grams of protein per kilogram of bodyweight Â
per day for those wanting to fully maximize their growth. However, 1.6 should be fine for most.Â
Before we close, letâs go back once more to the figures. Yes, you will build less muscle if you Â
eat less protein, but you will STILL BUILD MUSCLE. Just make sure that you are resistance training, Â
like lifting weights, on a regular basis. Down the line, if you can change your Â
protein situation, then great. But, donât feel like itâs not worth Â
pushing for your goals just because youâre not getting the supposed âoptimalâ levels of protein. Â
Getting close enough can still lead to great r esults, so keep at it.Â
And thatâs it for this one. I hope you found this video useful. Also, Â
