Combining resistance training with a high-protein diet (1.2–1.6 g/kg/day) significantly enhances muscle hypertrophy and strength gains compared to resistance training alone.
To maximize muscle growth and strength, combine regular resistance training with a diet providing 1.2 to 1.6 grams of protein per kilogram of your body weight daily. This combination is the most effective non-drug method for building muscle. Ensure your protein intake is adequate to support the mechanical stress of training, as this synergy drives greater hypertrophy than training alone.
The integration of a high-protein diet with a structured resistance training regimen has been shown to significantly enhance these adaptations... By providing the necessary amino acids for muscle repair and growth, a high-protein diet complements the mechanical stimuli from resistance training, leading to greater increases in muscle mass and strength.
Why this rating
Based on a comprehensive literature review citing systematic reviews and meta-analyses, though the paper itself is a review, not a primary trial.
