What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Consensus on protein requirements across populations
A systematic review and meta-analysis of all nitrogen balance studies in healthy adults, analyzing data from 50+ studies to determine the average protein requirement and recommended intake levels.
Long-term health outcomes at recommended protein intake
A 20-year cohort study following 15,000 adults consuming 0.83 g/kg/day protein, monitoring health outcomes, muscle mass, and metabolic markers annually.
Adequacy of 0.83 g/kg/day for physiological needs
A randomized controlled trial with 200 adults assigned to 0.83 g/kg/day protein intake for 6 months, measuring nitrogen balance, lean body mass, and biochemical markers of protein status.
