Mathematical Formula & Scientific Methodology

Formula: Muscle Protein Synthesis (MPS) Refractory Distribution Model

Protein per Meal = Total Daily Protein / Meal Frequency

Maximizes the area under the MPS curve by taking advantage of the ~3-4 hour refractory period of muscular protein turnover.

Model Assumptions

  • High biological value protein sources with complete amino acid profiles

Variables & Standard Units

SymbolPhysiological MeaningUnit
Total Daily ProteinPrescribed daily protein targetgrams

Scientific Limitations

  • Plant proteins may require slightly higher per-meal doses (~30-40g) to match the leucine density of whey or beef
