Kardashian isn’t afraid of going on drastic diets to lose weight fast. To squeeze into Marilyn Monroe’s famous dress for the 2022 Met Gala she dropped 15 pounds in just three weeks by cutting all carbs and sugar out of her diet and drank a lot of water. “Two weeks before [the Met Gala], I was 10 pounds down and I was so proud of myself,” she said. “Then I got down 15 [pounds] and it fit. I couldn’t believe it.” She claims that the diet was safe. “If I was starving and doing it really unhealthy, I would say that, of course, that’s not a good message. But I had a nutritionist, I had a trainer. I have never drunk more water in my life. I don’t see the criticism for other people when they lost weight for roles — they are [considered] geniuses for their craft,” she told Allure. “There are so many things out there that are so not accurate and not true.”

Kylie prefers at-home workouts. "I never find myself in a gym. I find myself on the floor of my bedroom, looking up on like, Google or Pinterest, workouts — and doing abs, lunges, squats. All that good stuff," Kylie revealed during an interview with Harper’s Bazaar. According to the star, she works out every day, sometimes twice.

3. Kim Works Out Like It’s Her Job

Kim doesn’t mess around when it comes to fitness. She trains with bodybuilder Melissa Alcantara, who dished on the details of their sessions to Women’s Health. “Her schedule is crazy, and mine is also crazy, so we work out really early in the morning at 6 a.m,” she said, adding that "85 per cent of our training is weight training, and the other 15 is made up of cardio" and that Kim works out six days per week for 60-90 minutes each time. Ball slams, burpees, sprints, and ladder drills to get her heart rate up are just a few of their exercises. "She’s super responsible, she never cancels – she’s the best client and athlete you can have," Alcantara shared. "It’s just her drive. She's like, ‘I have to work out, this is part of my life.' It’s all about the mindset."

"Today, at the shoot, I ordered a steak burrito and some rice, some enchiladas. I was feeling Mexican food vibes today. It really just depends."
