"  Rumors began circulating today that Jillian Michaels, long-time trainer on The Biggest Loser, plans to quit the show for the third time. Michaels previously left the show in 2006 and 2011. Jillian has previously expressed her displeasure with how competitive the show had become, though this past season she was also penalized for providing her contestants with caffeine supplements (without consulting the show&amp;#039;s medical team). A source tells E! News she&amp;#039;s become disillusioned, and in particular wants out following Rachel Frederickson&amp;#039;s &amp;quot;shocking weight loss.&amp;quot; Her unhappiness with that result was crystal clear during the show&amp;#039;s finale; she later criticized the aftercare system in post-show interviews. That said, neither Michaels or NBC have provided comment or confirmed the speculation\u2014at least not yet. This post originally appeared on Cosmopolitan.com. Follow REDBOOK on Twitter.
