Franz Ferdinand frontman Alex Kapranos fears the band's Australia and New Zealand tour is causing him to waste away - because he's burning calories faster than he can eat.

The band's energetic schedule means Kapranos is always on the go, and he's stunned by how much weight he has lost already.

He says, "During the last tour we were on, I seemed to lose weight. I'm trying to eat as many cakes as I can at the moment. I stuff my face like a glutton, but it seems to burn away."
