"A small study performed on young and elderly found that ingestion of 113 grams lean beef (30g protein) in a single meal increased muscle protein synthesis in both groups by 50%. Another group was served a large serving of 340 grams lean beef (90g protein). The study concluded that more than 30g protein in a single meal did not further enhance the stimulation of muscle protein synthesis in young and elderly."
If there is truth to this study, this means that no person, regardless of bodyweight or type would ever need to take in more than 180 grams of protein, assuming a "meal" is consumed every 3 hours, 6 times daily.
I consume 336 grams daily. I'm sure most guys here consume close to or more than that. Am I basically wasting 160 grams a day?!?
So what do you guys think about this? Any truth to it?
Few problems with the study, or your conclusions from the study.
1 - It was a small study. Limited samples yield results that are less robust when you generalize them.
2 - You're only looking at one study. This is not a reliable evidence base.
3 - The variables measured were age and protein consumption, they said nothing about bodyweight. All you can conclude from this is that AGE has no bearing on protein synthesis. The bodyweight of these people was not factored in. If you have more muscle to maintain, you will require more protein/amino acids to do this.
4 - Were these people weight training? If they weren't training why would they NEED more than 30g other than to maintain their base level of muscle mass/day-to-day repairs? If theres no requirement of course increased intake wouldn't have an effect.
