Round 1
Reviewer 1 Report
This systematic review and meta-analysis was conducted to explore the effect of protein intake on prevention and improvement of sarcopenia.
The work was conducted in a formally correct manner and the (few) studies on the subject were all taken into account. The discussion of the work can be improved. The authors should elaborate on the aspects of the excessive use of protein supplements, the possible damage to health and the ease with which the protein quota required for the prevention of sarcopenia is achieved through diet alone. It is also useful to look at the differences between plant and animal proteins and the risks associated with too much of the latter in the diet.
As the data are very clear, it would also be appropriate to change the title of the review, suggesting the futility of supplementation.
