the claim

The RDA of 0.8 grams of protein per kilogram of body weight is enough to maintain muscle in active adults.

the verdict
CONTESTED PARTIAL
Recorded sources
2 sources for · 5 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that the RDA of 0.8 grams of protein per kilogram of body weight is enough to maintain muscle in active adults?

Partly. One cohort study found adults consuming at least the 0.8 g/kg RDA had lower risk of functional dependence, and a nutrition reference confirms the 0.8 g/kg RDA figure. However, several reviews and studies indicate older or diabetic adults need protein above 0.8 g/kg to maintain muscle, so the evidence only partially addresses whether the RDA suffices for active adults.
