New study suggesting that previously suggested protein intake may need to be higher to maximize MPS for those with a habitually higher intake.
Thank you to Brad Shoenfeld who just posted this on IG.

Discuss....?The capacity to enhance whole-body net balance may be greater than previously suggested to maximize muscle protein synthesis in resistance-trained athletes accustomed to a high habitual protein intake.

I have not read this study yet but I noticed Menno Henselmans commented on it:
"In a new study by Mazzulla et al. (2019), the authors suggest protein requirements are higher than previously measured.
The current body of evidence strongly indicates you need only 1.6 g/kg/d of protein (0.72 g/lb/d) to maximize gains in strength and muscle mass. That's total protein intake for total bodyweight per day.
This evidence includes the latest meta-analysis and a RCT study I co-authored. You can find all the studies in my article on the Optimal Protein Intake on my website.
In the new study, the authors used the indicator amino acid oxidation (IAAO) technique to estimate the protein intake required to maximize whole-body protein balance.
They concluded 2 g/kg/d was needed.
However, the actual study measurement period was only 8 hours and directly after a full-body workout after 2 days of protein deprivation (1.2 g/g/d). So this study didn’t actually measure total daily protein requirements in normal scenarios but rather protein requirements in the immediate post-exercise period after being protein deprived.
It’s also worth noting that the study had only 7 participants and 2 previous studies using the same method reached protein requirement estimates of 1.5 and 1.7 g/kg/d.
Moreover, whole-body protein requirements may not coincide with muscle protein requirements. After a certain point, the requirements for maximum muscle growth may be covered, but additional protein may still stimulate protein synthesis in other tissues, such as skin, hair and organs.
In conclusion, this study doesn't come close to showing we need 2 g/kg/d of protein. It rather suggests we need a correspondingly high protein intake specifically post-workout, if we didn't have that much protein in the period beforehand.
In line with this evidence, I recommend higher protein intakes per meal in the anabolic window after your workouts. That's when protein synthesis levels can reach much higher levels than normal and most of your recovery and gains take place.

Thanks for Mennos take on it. Interesting.
Either way it doesn't change my thought on my own intake, I'm already up there.
Yes I think it would be worth it to get on IG. I don't have or use FB but on IG you'll get a pop up notification/sound when someone posts something new if you set it to do soNASM CPT

@Mrpb
Just read Mennos take on that study finally in detail and he raises some good points about the flaws in that study
My question is why even do/publish that study and stir up protein intake debates by reaching the conclusion they did?
Makes no sense
Curious to see if Brad comments on Mennos take on this; after all Brad did post it on his IG so I suppose he has no issue with the studyNASM CPT

So the argument is the body builds a tolerance to protein intake which blunts MPS; not sure I'd buy into that without some solid evidence. Sure people build tolerances to many substances, but protein seems unlikely, the body is pretty efficient and this would be rather backwards.
Also... of course it makes sense... clicks get money, say something to get attention and clicks.Short cuts to success are often paved with lies.
