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.
