The 19-year-old actress said she has already noticed a drastic improvement in her health since she eliminated meat from her diet six months ago.
"Going vegetarian was probably one of the best decisions I've ever made (sic)," Moretz tweeted.
The "Kick-Ass" star, however, is still trying to completely quit eating fish.
Pescatarian would be the term but I aim for fully vegetarian. Side note I'm also dairy free ... It's really inhumane how they abuse cows for their milk. I feel healthier and morally so so much better I do eat fish tho sometimes still (sic)," she added.
