Talk about a revenge body! Kourtney Kardashian is in the best shape of her life, and she’s worked very hard to get there. The mom of three recently split with 25-year-old model Younes Bendjima, and it seems that she’s not sweating it a bit. Instead, she’s focusing on herself and her family — and her rocking bod. Kourt’s kept up her busy workout schedule and rigorous diet despite the drama in her life, and it shows.

“I believe we have one life to live, and I would like to live it feeling my best,” says the Keeping Up With the Kardashians star and single mom, who shares kids Mason, 8, Penelope, 6, and Reign, 3, with ex Scott Disick. To get extra lean, clean-eating Kourtney went on the popular Keto diet. Though she usually limits her gluten and dairy intake, that meant also sticking to three low-carb meals a day that are high in protein and healthy fats, like avocado pudding for breakfast or a salad with chicken for lunch. She’ll also munch on fresh fruit and almonds in between meals. It’s not an easy plan to follow, but the star is no stranger to a little self-discipline.

Registered Dietician and SlimFast Plan Consultant Maryann Walsh says snacking actually helps keep hunger at bay. “A good grab-and-go option is a SlimFast Keto Peanut Butter Cup Fat Bomb, which contains healthy fats,” she tells In Touch magazine. “Fat is a staple of the Keto diet and helps keep you feeling full.”

No wonder Kourt’s a fan! “It was a really positive experience for me,” says the 39-year-old, who advises followers to check with their doctors before starting the intense eating plan. The way it works is by shifting the body into a metabolic state called ketosis so that dieters burn fat instead of carbs for energy. And if you’re wondering if it works, well, Kourt is kind of living proof. But she also kicks butt in the workout department, often exercising with her trainer, Don Brooks, and sister Khloé.

“I know for my body, I need [at least] four to five days a week of working out… I’m on a workout kick,” says Kourtney, who alternates between cardio work (like running, jumping rope, or using the stair climber) and strength-training (using resistance bands, body weight, or kettlebells). Her commitment to fitness has made a huge difference in getting her the body of her dreams. “I never made working out a priority [before],” she says, “but now it makes me feel so much better mentally and physically… I try to take time for myself to work out every day.”
