But talking to TV presenter Lorraine Kelly on Lorraine earlier this week, the Keeping Up With The Kardashians star mentioned that getting fit and healthy was a long slog.
Talking about how she managed to obtain her stunning and now world-famous figure, Khloe said, "I always say the turtle wins the race so for me, [my transformation] was a really slow process. But I didn't seek out to lose 20 pounds in 20 days - that wasn't my goal."
Khloe - who just celebrated her 32nd birthday - continued, "I just wanted to feel strong mentally. I was always like, 'Oh I'm big-boned' but once I started losing weight naturally I was like, 'Wow ok' now I'm going to get a trainer! Then six months later I was like 'I'm going to get a nutritionist.' Once I started taking my health more seriously I started seeing definition in my arms, [my] muscles and that motivates you more to keep working out."
Khloe revealed that exercising and altering her diet also had a profound effect on her emotional strength, which helped her through a difficult period in her life.
Last year, Khloe's ex-husband Lamar Odom took a drugs overdose which left him in a coma. The star and her family rallied around him during the time.
"Even just dealing with life experiences you feel good mentally [as well as] physically," Khloe said. "Everything."
Khloe - who also recently let us in on her body struggles as a teenager via her website and app - said that even though she feels amazing, she will still always pick a swimsuit over a bikini.
"I love one pieces and I think one pieces can be super sexy," Khloe said. "I don't think you need to show everything to be sexy and now one pieces have the high European cuts and I think they are great!"
She went on to say," I feel really comfortable in them so I am always a one piece girl but I think if you got it flaunt it. I wish I was one of those girls who could walk down in a bikini all the time but I just don't feel comfortable."
Lorraine is on ITV, weekdays from 8.30am to 9.25am.
