Robert Kardashian lost his battle with oesophageal cancer when he was 59 years old, and his daughter Khloé - who was 19 at the time - has admitted she ballooned in size after she ate "literally everything" in order surpress her feelings.

Speaking to a woman named Lauren on an upcoming episode of her new show 'Revenge Body with Khloé Kardashian' - in which the blonde beauty mentors men and women to encourage them to reinvent themselves both inside and out - she said: "I know, to a degree, how you feel. My dad died in 2003. I was 19. And when it set in, I was like, you spiral. For me, my spiral was food."

"I gained so much weight because I was so internally just suppressing so many things that it was like, eating me alive, and I was literally eating everything.

"We can't let these tragic things ruin the rest of our lives."

And whilst the 'Keeping Up with the Kardashians' star admits that hardship forced her to gain weight, she also revealed recently that her divorce from Lamar Odom - which was finalised last year - helped her to shed the pounds.

Khloé - who filed for divorce from the basketball player in 2013 - said previously: "I really needed an outlet mentally.

"I started working out, and the clarity I received from that was so needed, and it was so therapeutic, and as a by-product I started losing weight."

But Khloé insists that her new body is not just to "prove a point" and that she hopes to maintain her new physique.

She added: "I was like, 'Oh, OK, I see a little definition somewhere. Let me try keep this up.

"Then I got a trainer, and a few months later, a nutritionist.

"My journey has been a long one, but it's a lifestyle change.

"I'm not trying to lose 30 pounds in 30 days to prove a point.

"I want this to be for the rest of my life."
