The 30-year-old said she would be 'miserable' if she dieted.
Speaking in the May issue of Cosmopolitan UK, the Kourtney and Kim Take New York star said: 'Sometimes I pig out, and I still feel great, and think 'That was so worth it!' That's how I feel a lot of the time.
'I think, 'See this little dimple of cellulite here? It was so worth it for that cookies 'n' cream ice cream!'
'If I was stuck on a diet my whole life I would be really miserable. I love to eat. If you can't enjoy your life then what's the point? You can't torture yourself.'
Kardashian also insisted that she knows her body isn't perfect.
She added: 'I never aspired to be a size zero. I have cellulite. So what! I've never claimed to be perfect. It's crazy anyone should assume that just because you're in the spotlight, you're flawless.'
