Robbie Williams goes on juice diet

Singer Robbie Williams is reportedly determined to lose weight in time for the Australian leg of his 'Let Me Entertain You' world tour next week and is now following a juice diet to drop the pounds.

According to a source, the 41-year-old has stripped back his eating regime to just fruit drinks and freshly squeezed vegetable juices in order to shift some weight after piling on the pounds during his two-month break.

"Robbie's found it harder to keep the pounds off and maintain his body since giving up smoking a couple of years ago, so he has to work harder in the weeks leading up to performing if he wants to be able to look and perform at his best," mirror.co.uk quoted the source as saying.

"When he's not on stage, he does less exercise, eats more of his favourite foods like cake and crisps, and takes a little less care of himself diet-wise.

"He's been on juice diets before and tried protein shakes, and they seem to work best for him," the source added.
