Macro partitioning
Distributing protein evenly across multiple meals to exceed the leucine threshold in each meal results in greater muscle mass gains compared to uneven distribution where only one meal exceeds the threshold.
Spread your protein intake evenly across 3-4 meals throughout the day. This ensures that each meal triggers muscle protein synthesis. Avoid skipping meals or concentrating all your protein into one large meal, as this wastes potential anabolic opportunities and may lead to visceral fat deposition rather than muscle growth.
The ED-Whey treatment with evenly distributed leu produced multiple stimulations of MPS throughout the day and larger gastrocnemius muscle weights compared to the UD-whey that only achieved stimulation of MPS at a single meal.
Why this rating
Rat model study; long-term (11 weeks) but still animal-based.

- 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
