She’s hosting a new show in which people battle to lose weight for their weddings, but Sara Rue is grateful she doesn’t have to do so herself.

“It’s nice to not have that be a stressful thing,” the actress, who hosts the CW’s new reality competition Shedding for the Wedding, tells PEOPLE. “Planning a wedding can be stressful enough, and I’m glad I don’t have that to worry about.”

Rue, 33, who’s preparing to wed teacher Kevin Price in May, famously lost 50 lbs. on the Jenny Craig weight-loss program, and says she works hard at staying trim.

“I do my maintenance by exercising and watching what I eat, but of course I may want to lose a little bit more just so I look and feel great in my wedding dress,” says Rue.

But she scoffed at her trainer’s suggestion that she could stay focused by training for another half-marathon. “I was like, ‘Are you nuts?’ ” she says. “No way do I want that stress while I’m planning a wedding!”

For Rue, the best measure of her success is that she is now active and feels comfortable in her own skin. “On my honeymoon, I want to be able to flounce around in tiny shorts and a bikini top,” she says. “That would be ideal.”

Shedding for the Wedding, in which nine overweight couples compete to lose the most weight and win their dream wedding, premieres Wednesday at 9 p.m. ET on the CW.
