Usually when they eat tons of plants like that -- It means you aren't giving them enough water (or they just really love plants).
Honestly, try misting her more often, make sure you give her lots of water. Then try to revive your plants or buy new ones.
Live plants are much more beneficial (and in my opinion, prettier) than fake ones. For example, they hold humidity better, grow and provide more natural looking branches, and aren't as... fake... as fake plants.
Imagine if you went outside and all your plants were fake. That would look pretty drab

Just trying to put it into perspective because I don't understand why people will just "give up" when their plants begin to die, or switch to fake plants because they're easier.
It's very simple, just take care of your plants and cham, try different plants that are right for you (off the safe FLCHAMS list) and you and your cham will be happy.
Here is more information.

Fake plants are ok, but we suggest you have at least one live plant. Good, easy plants to take care of are:
Ficus benjamina, pothos, schefflera (keep in mind that these prefer good lighting and lots of water), hibiscus (you'll probably need a grow light for these), and other plants.
Reviving the plant is easy. Take it out of your enclosure and put it in a slightly shaded area that is not sunny all day. Your plant will be in shock if you put it in full sun. It will need time to get used to the new environment, so water it lightly every day and cut off any completely dead parts of the plant. Hopefully it will make a recovery.
