That's the question many have for Jennie Garth, considering she's a working mother of three who recently shed 30 pounds and is determined to keep it off.
The actress admitted to People this week that "maintenance" is a "daily" challenge, but it's all about keeping the proper mindset.
"You have to remind yourself what your priorities are," she said. "And remind yourself about staying healthy and living a healthy life."
It also helps that Garth has turned to gluten-free recipes, while also fitting in exercise as often as possible.
In whatever way she can.
"Every day, I try to schedule something in, whether it's hiking with my dog or jogging or going to the gym," said Garth, who's been linked romantically these days to Big Gigantic drummer Jeremy Salken. "Those are the things I'm focused on right now."
And it's clearly paying off. We always knew Dylan McKay made the right choice.
