Ok i have read mixed reviews.?

ok i have 5 frogs and a toad. The toad and 4 of the frogs are big enough to eat pinkie mice(and seem to love them) but i hear people say don't more than once a week they are high in fat. Here is my problem, i hate adding artificial stuff to my pets diet IE dusting powers, they don't seem to care for the Dusted crickets much, and Pinkies provide more nutrition than crickets. Has anyone had a frog/toad that was purely pinkie fed? and if so how was his health?Side note i breed mice so i have a good supply of pinkies.
