In the first example,
le cambiará la vida is probably what I would say. Improving one's health often changes one's life. You could also say,
le mejorará la salud.
In the second example, I think
cambió/mejoró todo would work. Or, maybe something like this would work:
Su cambio de actitud transformó el ambiente en el trabajo.
