The 19-year-old actress has already noticed a drastic improvement in her health since she banished meat from her diet six months ago, and now relies on the likes of quinoa to pump her body with protein.

Taking to her Twitter account on Monday (19.12.16), the blonde star said: "Going vegetarian was probably one of the best decisions I've ever made (sic)."

The 'Kick-Ass' star - who is also gluten-free - has eliminated dairy from her life but hasn't been able to give up fish altogether and still munches on sea creatures at times.

She added: "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)."

But making changes to her diet wasn't easy for the star and it took her a good "two weeks" to work out what to eat to ensure she retained her energy levels.

She explained: "The first two weeks were really hard, figuring out what supplements I should be taking to get all my energy levels right. I'm almost 100% carbohydrate free (sic)."
