Outcome Measures
Primary Outcomes (1)
Whole Body Protein Turnover
Isotope Tracer
24 hour
Study Arms (3)
Recommended dietary allowance (RDA) for protein
EXPERIMENTAL(RDA; 0.8g/kg/day) Protein intakes will be structured within two meals per day. A 2-day dietary lead-in will precede each dietary intervention. Study duration per subject will last about two weeks.
Habitual protein intake consistent with population level norms
EXPERIMENTAL(NHANES; 1.0g/kg/day) Protein intakes will be structured within two meals per day. A 2-day dietary lead-in will precede each dietary intervention. Study duration per subject will last about two weeks.
Optimal protein intake (OPI)
EXPERIMENTAL(OPI; 1.5g/kg/day) Protein intakes will be structured within two meals per day. A 2-day dietary lead-in will precede each dietary intervention. Study duration per subject will last about two weeks.
Interventions
0.8 g/kg/day protein intake
1.0 g/kg/day protein intake
1.5 g/kg/day protein intake
