Gerard Butler 'struggling with detox'

Gerard Butler has revealed that he is on a detox diet.

The actor has restricted himself to lemon water and cayenne pepper in an attempt to lose weight and improve his health, WENN reports.

However, Butler admitted that he is finding it difficult to stick to the regime without his trainer to motivate him.

"I'm on a cleanse right now," he said. "I have the lemon water! It's a nightmare because normally there's time constraints and I have my trainer and nutritionist to enforce the law.

"I'll literally have people there hiding cupcakes from me. Once my trainer caught me, he said, 'You're in that trailer over there, right? I heard you're eating chocolate cake', and I'm like, 'Me? No!'

"My heart is pumping so fast trying to sneak this cake when my trainer's not looking!"
