I have some weeks with no cooking too. Hard boiled eggs, raw milk cheese, and meat cooked elsewhere. I see how pleasant it can be. Maybe you can eat out for some suchi or steak tartare too.

JK's practice was older and sick people too. it does seem as if a teen could do the 67 g + 10% and be fine. He also doesn't address an active life except to say that manual laborers need the max protein.

Oh I just realized! JK would say she's already at goal weight.
Maybe it's time for re-shaping. Like T-Tapp, one of my favorite programs for getting tight (the opposite of fluffy?) and strong and shapely in very little time.
