The PHL has a fairly strong theoretical fit for delaying age-related frailty, although I would distinguish that from saying the PHL has been clinically proven to prevent frailty as a package. The strongest evidence is for exercise and adequate nutrition; the other PHL components potentially reinforce the biological systems that allow an older person to remain strong, mobile, metabolically resilient, and cognitively functional.
