article: Weight gain: Pope Francis has been told to cut down on the pasta by doctors . The Pope has been told by doctors that he must lose weight, it has been reported. Vatican medics told Francis to cut his pasta intake to two servings a week and take a daily walk, like his predecessor Pope Benedict XVI did. They are concerned about the sedentary lifestyle of the 78-year-old Catholic leader – who spends much of his time hard at work at his desk or in meetings – as well as his considerable weight gain since he took office two years ago, sources told Italian news agency ANSA. The Pope’s weight is thought to be aggravating his sciatica, a nerve condition which causes back pain. Francis himself has suggested that he does not expect to live to an old age. Two weeks ago he told Mexican TV he did not think his papacy would last long. And on a plane back from South Korea last summer he said that his reign would only last ‘a short time, two or three years and then… to the house of the Father.’ Now doctors have told the Catholic leader that he must shed a few pounds as the extra weight is making his sciatica worse, especially when combined with his intense travel schedule. But the pope who reacted by joking refers to himself as ‘the undisciplined one’ is taking little heed of their warning, continuing to tuck into a bowl of pasta every day. More walks: The Pope arrived on his popemobile at St Peter's Square for his general audience yesterday. He is being encouraged to take more walks in a bid to improve health .
