Miley Cyrus is denying rumors that say that she is anorexic, following a series of recent photos of the singer looking thinner than usual.

She took to Twitter to address her critics Monday. "For everyone calling me anorexic I have a gluten and lactose allergy. It's not about weight it's about health. Gluten is crapppp anyway!"

The 19-year-old later tweeted, "Everyone should try no gluten for a week! The change in your skin, phyisical and mental health is amazing! U won't go back!"

A gluten-free diet excludes all foods containing gluten, a protein found in wheat. Lactose is a natural sugar found in dairy products like milk. An allergy to either makes it difficult for the body to digest foods that contain them.What do you think of Miley's slim figure? Would you be willing to try a gluten- and/or lactose-free diet?
