Hilary Duff has expressed her disbelief at some of the fad diets Hollywood stars follow, and revealed that she opts for a healthy, balanced regime.

The 'Wake Up' singer has slimmed down noticeably since her days on popular children's programme The Lizzie McGuire Show, and whilst she admits there is the expectation for stars to be skinny by whatever means possible, she credits a sensible attitude to food and pilates for her transformation.

"There is definitely pressure. People are thin. I do worry about what I look like but I'm not going to let it control my life. I do try and eat healthily and exercise. Not because I have to, but because I want to do it for me," the 18-year-old told WENN.

She added: "I think some of the crazy diets that people try are really bad. There are ones where people eat six sultanas a day. The Atkins is wrong too. I don't think it's good to deprive your body of things like carbohydrates. Everyone should eat things in moderation."
