Kourtney Kardashian's Slim-Down Secrets

In the Kardashian family dictionary, the word discretion simply doesn't appear.

One moment we're learning about what Kanye's like in bed, the next we're discovering where Bruce buys his hair extensions. But while not every stitch of dirty laundry deserves to be aired, there are definitely some secrets we don't mind stealing from the first family of reality television. For example: How do they stay in such great shape, especially after having kids?

Thanks to Kourtney's ever-active social feeds, we've been able to study the weight-loss program she's followed since giving birth to her third child this past December. The 5-foot star, currently 120 pounds, recently proclaimed on Instagram that she "only has "14 stubborn pounds to go" until she hits her goal—which, in the scheme of things isn't all that much! Sure, Kourt is specifically working to shrink her post-pregnancy belly, but her healthy lifestyle tips can help anyone lose weight rapidly. Below, we weigh in on her get-fit tricks and tell you how you can get similar results at home, with research compliments of the bestselling Zero Belly Diet!

Kardashian Fit Trick #1: Get a Workout Buddy

Three weeks ago, Kourtney posted a photo of her and a friend flexing some serious guns. Although the caption didn't specify what the sporty-looking duo was about to get into, it's safe to say they were ready to break a sweat.

Why It Works: People exercise for an average of 34 minutes longer with a friend than they do when they hit the gym solo, according to the American College of Sports Medicine. And the longer you sweat, the more quickly you'll reach your goals! Next time a friend asks you to grab drinks after work, suggest taking a hike or checking out a new fitness class instead.

Kardashian Fit Trick #2: Don't Deprive Yourself

About a week ago, Kourt posted a photo of a delicious-looking Nutella pizza roasting over an open fire with the caption, "This is happening." The reality TV star is has said in the past that she typically munches on fresh protein smoothies, veggie soups, lean meats and salads, but she doesn't deprive her sweet tooth when the craving strikes—and that's likely one of the reasons she has so much slim-down success.

Why It Works: Although Nutella is anything but healthy, experts say giving into your sweet tooth can actually help you lose weight. "Occasionally including dessert can aid weight loss efforts by warding off feelings of deprivation and bouts of overeating," explains dietitian Cassie Bjork, RD, LD of Healthy Simple Life. "It can make it easier to stick with your healthy eating regimen for the long haul."

Kardashian Fit Trick #3: Kick Off Your Day with Resistant Starch

Two months ago, the health-minded mama posted a photo of her breakfast bowl. The caption read, "Monday morning breakfast. Organic oatmeal made with whole milk, bananas and cinnamon."

Why It Works: In addition to being more satiating than other popular breakfast options like cold cereal, oats are rich in something called resistant starch. As the name implies, it's resistant to digestion, so the body is not able to absorb as many calories from each molecule. And the cinnamon Kourt adds to her bowl isn't just for flavor; the spice contains powerful antioxidants called polyphenols that can reduce the accumulation of belly fat. Other findings suggest that adding a cinnamon to starchy meals may help ward off insulin spikes and control appetite. With so much science working in her favor, it's clear that regularly eating oats is one of the reasons Kourtney is seeing the pounds fly off so quickly.

Kardashian Fit Trick #4: Step on the Scale

Four weeks ago, the 35-year-old posted a photo of her scale, which showed that she was down to 120 pounds. Way to go! After giving birth to her second child, Penelope, Kardashian danced and dieted her way down to a svelte 105 pounds, but she's pleased with her progress so far. "First day that I have seen this number in a while," she captioned the image.

Why It Works: Although the number on the scale isn't the only way to judge weight loss success, research shows that those who avoid the ritual are less apt to reach and maintain their goals than those who don't. Step on the scale every Wednesday (researchers say that weigh ins are the most accurate mid-week) to make sure you are still trending toward your goal.
