Tonight Jame Oliver will continue his series Jamie: Keep Cooking and Carry On tonight. He will be making, from his home, a minestrone soup and a simple chicken curry.
He advised those looking to slim down to cut back on alcohol.
He told the Radio Times: Your average Brit drinks booze. Im not telling you what to do, but my rhythm now is only to drink at the weekend."
In another interview on his weight and health, Jamie told Men's Health: "I was getting three hours sleep a night, putting on weight and not really getting it.
"Id always gone to a trainer but I just f****** hated it. It was really boring. What I finally worked out was that its important for you to do it on your terms.
"Previously, if I organised training in my time, I hated it. But then I was like, why is it that I can get up for a 3.30am call and be on set and smash the shit out of it and yet getting to the gym is too hard?
"So I just shifted it so that the gym was on the way to work and it was part of the working day.
"The minute I did that I got really good at it. Its totally mental."
