Britney Spears struggles to give up food

Singer Britney Spears is trying to shed extra weight by cutting down her food intake, but she admits she is finding it very hard.

The 31-year-old is preparing for a two-year residency in Las Vegas, which starts in December this year. She will have to perform nearly every night, and to ensure she's in the best shape she is currently working on her body and fitness, reports eonline.com.

"I ate six times today, so I'm not always diligent with the food because I love food. It's really hard (to cut down) but you know, you have to do it," said Spears.

Nevertheless, she says she feels better when she is fit.

"I feel better though when I'm lighter, I do. My spirits are higher ... but it 's just, you love pizza sometimes. It just sucks, man ... it sucks," she added.
