Rachel Mcadams - Rachel Mcadams Too 'Tired' To Keep Up Vegetarian Diet

The Notebook star banished all meat products from her life and instead began relying on heavy carbohydrates to get her energy.

But animal-loving MCAdams admits she eventually caved in and returned to her carnivorous ways - because her body started to deteriorate without proper nutrition.

She tells Glamour magazine, "I was one (a vegetarian) once, but it made me very tired. I just ate pasta - I was the most unhealthy vegetarian ever! I'd like to try it again now that I know about (popular meat alternatives) quinoa and bulgur. I think I'd be better the second time around."
