US TV bosses have ordered a new series of Jamie Oliver’s fat-busting Food Revolution show, just days after his Emmy success.

The chef and broadcaster is turning his attentions to the country’s second biggest city, Los Angeles, in his ongoing battle to improve public health.

Critics had suggested he would struggle to win sympathy when he took his diet-improvement message to the US. But his first series was a ratings hit for the ABC network and landed an Emmy award for Outstanding Reality Series last month.

He will begin filming later this year. His first US series focused on Huntington, West Virginia – deemed to be the unhealthiest city in America – and is due to be screened by Channel 4 from September 13 with the new title Jamie’s American Food Revolution.

Food Revolution is based on the UK shows, Jamie’s Ministry of Food and Jamie’s School Dinners, which aimed to improve eating habits.
