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.

Other: Recommended Dietary Allowance of Protein

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.

Other: Habitual protein intake

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.
