(Cover) - EN Star Style - Alicia Silverstone says being vegan improves her looks.

The American actress and former fashion model says her diet of eliminating animal products from her food has a positive effect on her body.

The 34-year-old star became vegan in 1998 and believes her skin and hair have improved ever since, and she has spent less money on buying expensive beauty products.

"[Being vegan] changes everything. First of all your looks. You don't need any expensive creams anymore because you skin, hair and fingernails just look better. And you lose weight - without the yo-yo effect," she revealed in an interview with the German edition of Grazia magazine.

Alicia has confessed to suffering with less mood swings since converting to a vegan diet. The beauty also says the diet makes you pay particular attention to your body.

"Before I became vegan I didn't even know how good I could feel. I don't have mood changes that much anymore and I am much fitter. You became more sensitive in a good way and you pay more attention to your body," she added. (C) Cover Media
