The new mom said she's already lost 43 of the 50 pounds she gained during pregnany.

Now that she has a wedding to plan, Kim Kardashian is probably going to step up her post-baby weight-loss effort.

Already, the reality star has lost 43 of the 50 pounds she gained carrying daughter North West, according to People magazine - a feat she attributes to a strict Atkins diet.

'To get back to myself just makes me feel good again,' Kardashian, 33, told People.

The new mom also credits breastfeeding and exercising regularly to getting her shapely figure back. Not to mention, a little bit of motivation from her fiancé Kanye West.

'You want your guy to think you're really hot,' she previously said.

And he clearly does. The rapper proudly proclaimed he was 'heading home' after Kardashian posted a racy swimsuit photo of herself in a tight white one-piece to Instagram.

But the most famous Kardashian sister admitted she wanted to 'tune out the media' because of all of the scrutiny surrounding her body.

'Pregnancy for me was a lot tougher than people saw on my show or from magazines,' she said.

She reportedly endured symptoms of preeclampsia while carrying her now 4-month-old daughter, who was born in June. North West was born a few weeks premature as a result of her complications.

'I always envisioned that I would have this easy time just being pregnant, only my belly would get big,' the reality star previously said on an episode of 'Keeping Up with the Kardashians.'
