Effects of high-protein diet on renal function in healthy adults: a systematic review and meta-analysis
Kalantar-Zadeh K, et al.
Evidence is still building up
Summary
A systematic review and meta-analysis evaluating the effects of high-protein diets (1.5–3.5 g/kg body weight) on renal function (GFR, creatinine, etc.) in adults with normal kidney function. No clinically significant decline in renal function was found in adults with normal kidney function consuming high-protein diets.
Key findings
- 1
High-protein diets (up to 3.5 g/kg/day) show no adverse effects on renal function in healthy adults with normal kidney function
- 2
No clinically significant changes in serum creatinine or GFR were observed
- 3
These findings do not apply to patients with chronic kidney disease (CKD), who require protein restriction
- 4
Claims that high-protein diets 'damage' kidneys are unsupported in healthy individuals

Protein supplementation augments resistance-training-induced gains in muscle mass and strength (meta-analysis)
British Journal of Sports Medicine, 2018
A synthesis of 49 RCTs (1,863 participants). Protein supplementation significantly increased gains in lean mass and 1RM from resistance training; benefits plateaued beyond about 1.6 g/kg/day of total protein.
High-Protein Overfeeding and Body Composition in Trained Individuals: An 8-Week RCT
Journal of the International Society of Sports Nutrition, 2014
In 30 resistance-trained individuals (mean age 24), comparing a high-protein group (4.4 g/kg/day, 307 g/day) with a control group (1.8 g/kg, 138 g/day) over 8 weeks, there were no significant within- or between-group changes in body mass, fat mass, lean mass, or body fat percentage; the surplus of protein calories did not increase fat.
