Gwyneth Paltrow on beauty regimen: "Sleep is a major thing"

Gwyneth Paltrow has revealed that she considers sleep to be an important part of her beauty regimen.

During an interview on Sirius XM radio show Ask Dr Brandt, the Contagion actress shared what she believes are the secrets to looking and feeling her best.

"For me, sleep is a major thing. I don't always get it, and when I don't, I look like I've been hit by a truck," Paltrow said.

She went on to reveal that she generally follows a strict diet which includes homemade green juices, coffee with almond milk and large amounts of water. In addition, she often follows detox plans such as the Clean Programme.

"I find it very rejuvenating. It's like being high," Paltrow said of the 21-day cleanse.

Paltrow previously insisted that she refuses to diet but instead stays in shape with a healthy diet and exercise with trainer Tracy Anderson.
