I'm very shocked that someone would want risk killing or making their frog quite sick for an experiment like this. Just cause a frog eats something doesn't mean its healthy for it (some frogs even eat rocks which can end up killing them). The fact he ate it probably just means he was hungry.
Have you even looked to see how many things Cheetos contain? Artifical food colours etc. They also are full of salt. You probably risked not only poisoning the frog but possibily with feeding it salt, you may of risked giving it serious issues eg heart issues.
