Alison Sweeney recently opened up about why she left 'Days of Our Lives,' the soap opera she'd starred on for 21 years, to focus on hosting the reality show, The Biggest Loser.

“I was doing two full-time jobs working at 'Days of Our Lives' and hosting 'The Biggest Loser,'” she revealed in an interview with Larry King. “It just got to be too much. Watching my son go into the third grade and my daughter start kindergarten, I realized that I was missing out on a lot and they were missing out on a lot.”

And the actress seems happier than ever with her hosting gig on the weight loss show. Just recently, she shared a promo video for the weight loss competition and seems to be very excited about the contestants' progress.

"Contestants looked amazing last week – excited to see their confidence Thursday! #BiggestLoser," she wrote on Twitter.
