Since you distinguish "practical advice" from "theological aspects of everything", the latter by which I think you mean "faith & morals" [the competency of the pope], then by CCC 891 & 892, this does not require adherence to with the obedience of faith or religious assent.
Since the Pope is Father, good children listen with profound respect to even the simplest advice of the common Father and try sincerely to put it into practice. [cf. In Conversation with God, 68.3, Francis Fernandez, Fourth Sunday of Easter, THE GOOD SHEPHERD. LOVE FOR THE POPE.]
Assuming of course, just as in the case of an earthly father, that the practical advice is good.
The Pope is also Pastor, and provided he speaks in the name of the Good Shepherd, the sheep will hear his voice, if not, the sheep will flee from him, for they do not know the voice of strangers. [Cf. Jn 10:1-6]
