Khloé Kardashian sought ''refuge'' in the gym.

The 'Keeping Up With The Kardashians' star has admitted she exercised more when she was having ''issues'' with her estranged husband Lamar Odom.

She said: ''When me and Lamar were having issues, I decided to channel my energy into working out ... if I went out with my girlfriends I would be hounded by paparazzi and made to feel more humiliated.

''The gym was my only refuge. I could put music on and dance around with my girlfriends and be silly.''

The 30-year-old television personality, who is known for her curvy figure, insists she has never felt fat but admits she was ''unhealthy''.

She added: ''I have never felt 'fat', I just didn't realise how unhealthy I was until I look back at pictures.

''In the moment I felt so beautiful and I remember walking down red carpets with my make-up done in a little sparkly dress and I thought I was so cute. I had all this confidence.''

Despite having lost an impressive 30 pounds, Khloé says she still gets sent hateful messages about her size.

She told the Cosmopolitan magazine's Body issue: ''Now on my Instagram page people comment saying 'I liked you better when you were bigger' and I think, 'Thank God I don't live my life for other people because I'd be in a constant tug of war.'''
