Because Khloe Kardashian’s weight is fluctuating all the time, reports of a possible pregnancy emerge online almost with clock-like regularity. In a video to her fans, the reality star explains which is her biggest struggle.

The 26-year-old reality star has made a habit of taking questions from her fans and she’s now answering them in videos that she posts on her official blog.

In the first video of the kind, Khloe explains how she always goes out of her way trying not to speak of the things that stress her because she likes to think of others too.

She also says that one of her biggest challenges in life remains – and will probably always be – her weight. For years, she believed she was not good enough for whoever might be looking at her.

Granted, that last part of the problem she now has under control, but the fact remains that her weight will always oscillate and thus make her have certain self-esteem issues.

“My weight is always going up and down. I’m always fighting that. I feel like no matter what I do, I never look good enough to everybody else,” Khloe says in the video for her fans.

“I think my weight is my biggest lifetime struggle. It’s not the biggest thing in life, but it does get you down sometimes,” she adds.

Back when she was younger, her body image problems were even worse, the reality star goes on to add.

“That’s been a struggle that I think I’ve gotten ahold of, not caring what other people think. But as much as I say that, other people’s words eventually come and do hit you hard,” she says.

This is not the first time that Khloe is being so open about her weight and her self-esteem issues.

In October last year, for example, she revealed how she used to be bullied in school for being “ugly and fat,” mostly because she was always being compared to her sisters Kim and Kourtney.
