He told the paper: "Growing up as an Irishman, potatoes were our main ingredient, but people in this industry taught me that potatoes and rice are your enemy,"
"When I was 25, I began the Atkins diet with Mark [Feehily, his fellow Westlife band member].
“We'd have steak, eggs and bacon - all protein, though it wasn't the real Atkins diet because I'd still eat vegetables, such as carrots. I've been on and off it for years."
Speaking on the merits of the law carb diet Brian said.
"When I'm on it, I can lose up to half-a-stone in three or four weeks.
“I’m eating normally now, but when I have work commitments, such as TV presenting, I'll do zero carbs and high protein.”
