The body-builder-turned-politician said people should go vegetarian for a couple of days a week to reduce the damage farming does to the environment.
He told the BBC that livestock was responsible for nearly 30% of global greenhouse gases.
But what if there is another way? BBC Persian's Sahar Zand travelled to an unusual restaurant in west Wales to find out.
