They preferred partying and drinking to exercise and Sam said she's gained 50 pounds while Nicole put on 75 pounds,

Sam also revealed they had not had sex in eight months.

She also revealed that she she's been embarrassed to be seen in public due to her weight gain and avoids eye contact.

'Oh, I've been there,' Khloe revealed as she recalled being overweight.

She added: 'If I saw someone, I would still look down, even though obviously they could still see me. But just not having the eye contact, I felt much — I felt safe by not looking them in the eye.'

Sam told Khloe how she gained weight when she started dating Nicole who was her first girlfriend.

'It was an instant connection, I mean, something I've never felt before. And so, we focused on doing fun things and hanging out with each other. I didn't realize all these things that we were eating and doing. I blinked, and I had gained the weight,' Sam said.

Eye contact: Sam said she was afraid to make eye contact due to being overweight

Khloe replied: 'Whenever people get into new relationships, I think that it's natural to get consumed in them. You kind of lose track of your own personal life and your wants.'

Sam was hoping that Nicole would lose weight with her to salvage their relationship.

The Keeping Up With The Kardashians star also provided a trainer to former Coastal Carolina football player Dexter.

Dexter wanted to create a revenge body to get back at his father Robert who had been taunting him about being overweight.

During his initial meeting with Khloe, Dexter talked about being teased as a child for being overweight and for his man boobs.

Dexter explained that after losing his starting position in college his pro football career aspirations crumbled and he turned to food for comfort.

'Well I'm an emotional eater myself, because I've always been overweight as a kid,' Khloe told him.

She explained: 'If I was stressed out or sad, I would eat. It felt good and that was my form of comfort.'

'So I had to learn how to then put all my energy into something more positive and healthy for me, which is how I fell in love with working out,' Khloe said.

Khloe assigned Sam and Nicole to celebrity trainer Harley Pasternak.
