Kim Kardashian is more confident than ever after losing weight.

The socialite - who recently split from Reggie Bush - is delighted with her new slimmer figure and feels much more comfortable wearing a bikini.

She said: "I've lost five pounds in five days. I really wanted to just buckle down and get rid of the tiny bit of excess weight I was carrying.

"It gave me a lot of confidence with my body. I work out to feel good about myself -- and sure, it doesn't hurt if someone notices.

"I used to be so shy and insecure walking around in a bikini doing shoots and things. It's amazing how much better I feel and I was really proud of myself for just sticking to my diet."

To shed her excess weight, Kim cut out carbs in favour of lean proteins, fruits and vegetables and added to her exercise regime.

She added to Life and Style magazine: "I made sure that in addition to my gym workout, I did freestyle cardio outdoors. I went running or made sure I did as much walking as I could. I really kept active."
