Number of participants that the trial has enrolled
5402
Results
A total of 5402 study participants from 105 articles were included. In the multivariate spline model, the mean increase in lean body mass associated with an increase in protein intake of 0.12 g/kg of body weight per day was 0.39 kg (95%CI, 0.36-0.41) and 0.12 kg (95%CI, 0.116-0.14) below and above the total protein intake of 1.3 g/kg/d, respectively.

Background: Muscle mass is essential for health promotion and maintenance; however, consensus regarding the effectiveness of protein interventions in increasing muscle mass is still lacking.
Objective: To evaluate the dose-response relationship on the effects of protein on lean body mass (or fat-free mass).
Data Sources: PubMed and Ichushi-Web databases were searched, and a manual search of references from the selected literature of this study and included studies of other meta-analyses was conducted.
Study Selection: Randomized controlled trials evaluating the effect of supplementary protein intake on lean body mass which enabled group comparison were included.
Data Extraction: Two researchers independently screened the abstracts, and five researchers reviewed the full-texts.
Results: A total of 5411 subjects in 105 articles were included. Dose-response analysis using a multivariate-adjusted spline model showed that lean body mass significantly improved with about 5 g/day of supplementary protein intake; this effect further increased with supplementary protein intake of 50 g/day or more.
Conclusions: Increasing daily protein intake can help sustain and improve muscle mass in various populations irrespective of sex, age, and exercise habits.
