Khloe Kardashian shares incredible before and after photo from 18kg weight loss

She's rightly proud of her new, slim yet curvaceous physique. 

The 32-year-old posted an incredible before and after shot on Instagram adding a long caption, finally ridding herself of 'the chubby one' tag of her slender Kardashian-Jenner sisters.

'If you were to ask me five years ago if I ever saw myself being completely in love with fitness and health. That I would be an inspiration to many others, that I would be the push that others needed to find their way. I would've laughed in your face.

'Me? The chubby one? No way! But now I can't see myself ever stopping!' she wrote.

'I am completely honored and taking my role seriously in helping motivate and teach people what I had to learn to better myself from the inside out. Becoming stronger mentally so I can't let the little things break me down. 

'I see myself only getting better and better! I can't believe how far I have come! I almost can't believe that was me! If you've lost your motivation don't beat yourself up about it, negative thoughts only turn into negative realities.

'By keeping positive about your body, your inner health, your mental sanity, your fitness and what you're trying to achieve, you're way more likely to succeed.

'My fitness journey was for myself and myself alone. On my terms and on my timeline! Cheers to us becoming better than we were yesterday! #RevengeBody.'

Khloe began taking control of her life, and her body, in 2015 after her marriage to Lamar Odom started to fail and she's since written a book – Strong Looks Better Naked – about her transformation.

'Mine was a really slow process. I didn't seek to lose 20lbs in 20 days. That wasn't my goal. It was more that, emotionally, I just wanted to feel strong,' Khloe said of her weight loss last June.

And she always had excuses for her fuller figure in a family full of skinny Kardashian-Jenner women.

'I was 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.

But it wasn't easy: 'The first 45 days you're like, 'F*** this,' she revealed in 2015.

'But it's just as much for all my critics who called me 'the fat one' for my entire existence.'
