British actress Kelly Brook is the latest star to convert to an all-natural macrobiotic diet - but she has failed to kick her love of cheeseburgers. Brook has followed in the healthy footsteps of Gwyneth Paltrow and Madonna by attempting to switch to the eating programme - which involves eating only organic, seasonal foods, and separating the edibles into 'Yin' and 'Yang' for the perfect dietary balance. But Brook is upset cheeseburgers are not on the macrobiotic menu. She says, "I'm a fan of macrobiotics because I love the idea of eating what's growing in your surroundings - seasonal, organic and whatnot. "(But) I really love cheeseburgers - that's my biggest weakness."
