Macro partitioning
Pre-sleep protein supplementation (20g or 60g bolus) does not improve performance, body composition, or recovery in British Army recruits undergoing basic training.
If you are undergoing intense military-style or high-volume training, taking 20-60g of protein right before bed will not give you extra strength, muscle, or recovery benefits compared to just eating enough protein throughout the day. Focus on total daily intake and training quality instead of specific supplement timing.
We conclude no benefits of pre-bed protein supplementation to improve performance, body composition and recovery during BT.
Why this rating
Randomized controlled trial with a large sample size (n=122) and rigorous controls (isocaloric placebo), though specific to a unique population (military recruits).

- 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
- Trans fats should be completely eliminated from the diet, as they increase LDL cholesterol, decrease HDL cholesterol, and are directly associated with increased coronary risk.Strong
