Cheryl Cole joins blood type diet

Cheryl Cole has revealed details about her new diet.

The Girls Aloud singer is joining a host of celebrities, including Martine McCutcheon and Cliff Richard, who control what they eat based on their blood group.

She told Hello! magazine: "Recently my mother told me about 'Eat Right 4 Your Type', in which you're told what to eat and what to avoid depending on your blood type.

"It has made such a difference - not so much to my shape, but to how I feel and my energy levels. Before I was like 'energy schmenergy' and didn't believe it. But now I believe it 100 percent."

The star added: "I watch what I eat, not to stay slim but to feel good. My only trouble is that I can't do without sugar.

"I think I might have some sort of sugar imbalance. Sometimes I feel like I just need a chocolate bar.

"To be honest you can't put yourself under that much pressure, so I don't deny myself anything."
