Enhanced protein intake on maintaining muscle mass, strength, and . . . Figure 3 demonstrates the relationship between the quantity of protein intake and changes in muscle mass An intake exceeding 1 3 g kg day is anticipated to lead to an increase in muscle mass (represented by line A), while an intake below 1 0 g kg day is linked to a higher risk of muscle mass decline (represented by line B)
Dose–response relationship between protein intake and muscle mass . . . A recent meta-analysis of RCTs reported the dose–response relationship between protein intake and increased muscle mass in healthy adults 14 However, this report mainly demonstrates the magnitude of the effect in the dose–response curve, and thus the dose–response relationship between increased muscle mass and protein intake cannot be
Systematic review and meta‐analysis of protein intake to support muscle . . . protein intake recommendations have traditionally been the same for adults (>18 years old), regardless of age or sex Nevertheless, a higher daily protein intake (1 2–1 6 g kg BW day) has been suggested to improve lean body mass gain or maintain muscle mass in young and old healthy adults 5,10,19 Previous meta-analyses have been conducted to
Best Protein Intake for Retaining Muscle Mass While Dieting Several studies over the years have attempted to determine the best protein intake for muscle retention Helms et al (2014) recommended 2 3–3 1 grams per kilogram (1 04–1 4 grams per pound) of fat-free mass per day for lean, resistance-trained individuals in a caloric deficit 5 However, this range was based on limited experimental data, primarily from six studies
Systematic review and meta-analysis of protein intake to support muscle . . . Research questions focused on the main effects on the outcomes of interest and subgroup analysis, splitting the studies by participation in a resistance exercise (RE), age (<65 or ≥65 years old), and levels of daily protein ingestion Three-level random-effects meta-analyses and meta-regressions were conducted on data from 74 RCT
Preserving Healthy Muscle during Weight Loss - ScienceDirect Weight loss, achieved through a calorie-reduced diet, decreases both fat and fat-free (or lean body) mass (44, 45, 46) In persons with normal weight, the contribution of fat-free mass loss often exceeds 35% of total weight loss (47, 48), and weight regain promotes relatively more fat gain (49) In persons who are overweight or obese, fat-free mass contributes only ∼20–30% to total weight
Synergistic Effect of Increased Total Protein Intake and Strength . . . Moreover, the dose-response relationship between total protein intake and muscle strength augmentation in the present study resembles the result of the previous meta-analysis in that gain in muscle mass with increasing total protein intake begins to plateau at similar total protein intake (1 5 or 1 6 g kg BW d) There were no major differences
The Role of Protein Intake and its Timing on Body Composition and . . . For meta-analysis on the timing of protein intake, both adult and older adult groups were merged and outcomes were assessed using indirect comparison, i e protein groups were compared to control groups with subgroups representing different timings of protein intake Meta-analyses of the timing of protein intake for the obese group was
Effects of protein supplementation on lean body mass, muscle strength . . . A third explanation for the contradictory findings of protein intake on lean body mass changes may relate to the contribution of protein intake–induced change in lean organ mass Animal studies have demonstrated hypertrophy of organs such as the kidney and liver in response to high-protein diets ( 91 , 92 ), which may contribute to the
The Effects of High Protein Intakes During Energy Restriction on Body . . . the 1840’s by von Liebig that a daily protein intake of 120g would be sufficient to assure the basic physiological needs of the average man (Liebig, 1841) This value was based on the average protein intake reported by German workers at that time and was later challenged by Chittenden in 1904 (Chittenden, 1904)
The Role of Protein Intake and its Timing on Body Composition and . . . Higher total protein intake (1 2–1 5 g · kg-1 · d-1) is proposed to help preserve lean body mass (LBM) and improve body composition during weight loss in adults (1 , 2 , 3 , 4 Resistance exercise training, in combination with dietary protein supplementation, has been promoted as an effective approach to attenuate the loss in muscle mass with age (3)
