Kim Kardashian

AKM-GSI

Kim Kardashian is embracing her signature style more than three months after giving birth to her and husband Kanye West's second child, son Saint West.

The 35-year-old Keeping Up With the Kardashians star was spotted out and about in Los Angeles Friday while wearing a sleeveless black maxi dress, paired with matching stiletto sandals, a '90s-style choker and sunglasses. She wore her black and golden ombré-dyed hair down and carried a light blue jeans jacket.

Kim, who often dons black and has been seen sporting similar black dresses over the past week, has been working hard to lose the baby weight after welcoming Saint. In January, she announced she had started the low-carb, high-protein Atkins diet to drop the pounds and had become a spokesmodel for the company. She also gone on the same diet two years ago after giving birth to her and Kanye's first child, daughter North West

"I gained 60lbs during my pregnancy but have been an extra 10 lbs up for the last few years so it's time to really get to my goal," she tweeted. "This is going to be soooo f--king hard but I can do it and I can't wait to share it all with you! #BeastMode #WhosWithMe ?!?!?!"

Kim, who is 5'3", said that toward the end of her pregnancy with Saint, she weighed 190 pounds. She said her goal weight is 120. Kim revealed on her website this week she had lost 42 pounds and had 28 more to go.

Her nutritionist, Colette Heimowitz, vice president of nutrition and education at Atkins Nutritionals, told Redbook magazine this week Kim eats 1,800 calories a day. She said the reality star's daily meals consist of four to six ounces of protein, four ounces of cheese, eight to 10 servings of veggies and two tablespoons of added fat. She is allowed to eat sour cream, half-and-half and butter in moderation but is discouraged from consuming sugar, sweets, cakes, crackers, white flour and white rice.

A source had told E! News the reality star has been "staying on track with her weight loss progress" and is "taking it day by day."

"Running around with the kids definitely helps with shedding some weight," the source added. "And she has been working out and eating healthy."
