Consuming 30g of protein from lean beef immediately following resistance training may augment chronic adaptations in strength and lean tissue accretion compared to a placebo, though its efficacy relative to whey protein remains to be determined by this ongoing trial.
This study is currently a protocol and has not yet published results. However, it suggests that consuming ~30g of protein from lean beef immediately after resistance training is a viable strategy to potentially enhance strength and muscle gains. If you prefer whole foods over supplements, lean beef is a high-quality source of protein and micronutrients. Ensure you are doing consistent resistance training (3x/week) and consuming this protein within an hour post-workout.
Beef may have a positive effect on muscle strength and body composition changes during RTEX, however, there are few high-quality RCT’s examining the potential of lean beef ingestion to augment chronic RTEX-induced adaptations such as strength and muscle accretion.
Why this rating
This is a study protocol; no results are available yet. Evidence is currently 'awaiting peer review' and based on power calculations from previous meta-analyses.

- Total daily protein intake of 1.6 g/kg/day is sufficient for maximizing resistance training-induced muscle gains, with an upper confidence interval of 2.2 g/kg/day.Strong
- Resistance exercise training combined with sufficient dietary protein intake acts synergistically to maximize skeletal muscle hypertrophy, with protein intake saturating around 1.6 g/kg/day for general populations and potentially requiring 2.0-2.2 g/kg/day for resistance-trained individuals.Strong
