The Atkins diet sure seems to be working wonders for Kim Kardashian!

The new mom posted a photo of herself on Instagram last night donning a tiny white bathing suit, looking slimmer than ever.

The outfit certainly doesn’t censor Kim’s, uh, assets and the reality star’s boyfriend Kanye West didn’t seem to mind in the slightest. In response to the racy photo, Kanye tweeted, “HEADING HOME NOW.” Let’s hope little North West had a sitter!

Kim has showed off her post-baby body before, but has yet to shown so much skin. Up until now, the reality star has stayed relatively clothed, sticking to long dresses and jeans.

With Kim’s restrictive diet since giving birth to North four months ago, we think she deserves to show off a little bit! The new mom has been following the Atkin’s diet since giving birth, cutting out all carbs and focusing on proteins instead.

“She’s working out here and there, but it’s mainly about the food, Atkins-style,” a source told Us Weekly last month. “In August, Kim got frustrated because she hit a plateau, even though she was eating mostly protein and veggies.”

Whatever the problem was, Kim certainly seems to have made it over that plateau!
