Kim Kardashian has fluctuated through the years.  Having used QuickTrim in the past, it seems Kim is back on the QT diet pill wagon – especially after beau Kanye West has put the pressure on her to lose 20 pounds.

Expressing her frustration with losing weight, Kim tweeted the below after working out with her sister Kourtney – who gave birth to Penelope Scotland back in July:

“How is it that @KourtneyKardash & I have the same amount of weight to lose but she just had a baby! SMH help! LOL (sic)”.

She added:

“Since I started QuickTrim again a few weeks ago, I’m down 6 lbs!!! Yay best feeling. I was getting discouraged but now I’m so motivated!”

Admitting that her relationship with Kanye hasn’t helped her in the weight department, she told InStyle magazine:

“I’m hoping to slim down a little bit, and I’m not afraid to say it.

“I think everyone goes up and down in whatever that comfortable love relationship phase is where you like to eat out, but now it’s time to get it together again.”

Do you think Kanye should be “controlling” or putting his two-cents in about Kim’s weight?
