The talk show host - who performs with professional partner Derek Hough on the show - is pleased to have lost weight on her arms because she "hated" that part of her body.
Ricki - who announced her engagement to Christian Evans in August - told People.com: "I've lost a lot of inches all over. Definitely in my arms, and my arms were particularly one of the things I hated most about my body, so it's nice to see them slimming down."
But the 43-year-old brunette is not setting her sights on looking like 'Dirty Dancing' star Jennifer Grey and singer-and-actress Chynna Phillips - who was voted off the competition last week - despite giving "110 per cent" effort.
She added: "I'll never look like these women and these professional dancers.
"I'm exhausted. I'm committing to this 110 per cent ... coming in with a good attitude ... and going home and eating a balanced meal. It's really that simple."
Ricki - who has sons, Milo, 14, and Owen, 10, from her previous marriage - recently explained losing 15 lbs on the show has made shopping for wedding dresses much easier.
She said: "I'm looking for wedding dresses, and I just want to feel good about it and what I put on.
"Christian said, 'Honey, it doesn't matter what you are. I love you. It's about you being happy.' "
