David Cameron lost 13 pounds in three months by cutting out peanuts

British Prime Minister David Cameron has lost 13 pounds in the last three months by eating fewer carbs, according to an interview in The Times magazine.

The 48-year-old attributes his recent weight loss to "giving up biscuits and peanuts," The Times writes.

Cameron, who is running for re-election in May, has been open about his battle of the bulge in the past. In January, he said he was cutting out bread after putting on weight over Christmas.

The British leader seems to be staying on track. During his 24-hour interview with Times writer Jenni Russell, Cameron munched on a packet of skinny popcorn and drank water for lunch.

The prime minister appears to be taking after chancellor George Osbourne, who lost weight by following the celebrity-loved "5:2" diet, which involves eating normally for five days a week and "fasting" for two.

Although some people question the science behind the 5:2 diet, also known as the FastDiet, it has lured in many weight-conscious men and women with the promise of shedding pounds more quickly than other diets.

Cameron, however, has chosen a more traditional method of weight loss: running every other day.

"I'm not doing 5:2. I couldn't cope with either 5 or 2," he said of Osbourne's dramatic diet, according to The Telegraph. "I need to eat properly, but just cutting some things out and exercising."

Cameron has always been an avid jogger. When he first became prime minister, his special forces team was too slow. Now, everyone on his protective team has to be athletic enough in order to keep up with the middle-aged British leader.
