Los Angeles: Actress Rosie Huntington-Whiteley prefers maintaining a balanced diet which includes plently of vegetables, smoothies and fish."I live in LA, where every fad diet starts and all the training techniques begin, but I have always kept my approach to health and fitness really simple," Huntington-Whiteley told Britain's Grazia magazine."My approach is a lot of vegetables, smoothies and fish ... I don't believe in fads. I believe in eating clean and balanced," the 26-year-old further added.The actress is fond of grinding her vegetable and making it into a juice, reports femalefirst.co.uk."I do a lot of juicing, a lot of green smoothies. I put all my super foods and supplements into my juice and I have that first thing. I drink two litres of water when I wake up and try to do four litres a day," she said.She also believes that playing sports also helps keep fit."My mum and my brothers are fitness instructors, so I grew up outdoors, playing sports and being active. It keeps my head screwed on. You can't be flying around and not look after yourself and expect to keep your body running," she said.
