Chrisley Knows Best star Savannah Chrisley has been posting a ton on Instagram lately about getting ready for her upcoming wedding to pro hockey player Nic Kerdiles. Now, Savannah says she’s turned to the South Beach Diet to help her look and feel her best before she says “I do.”

Savannah, 21, who has a partnership with South Beach Diet, btw, shared the news on Instagram Tuesday. “You all know by now that I’ve made a commitment to my health and definitely want to look and feel my best for the wedding,” she wrote, captioning a photo of herself posing in a cropped white button-up shirt.

“I just recently had an amazing photo shoot with my @southbeachdiet team and am very proud about how far I’ve already come,” she wrote. “South Beach has given me the confidence to feel good about myself, and within myself. If anyone out there is looking to get healthy and stay healthy, this is your program!”

In case you’re not familiar with it, the South Beach Diet is broken up into three phases, and urges participants to focus on eating food that’s high-protein, low-carb, and low-sugar, according to the program’s website.

Savannah also told People in a new interview that she started the diet earlier this year to try to get healthier. “It’s also just feeling good about myself and that was the biggest thing. I want to wake up in the morning and feel good,” she said. “That’s why I wanted to partner with South Beach. It’s been great for me because it’s easy and it works. It’s just about a healthy lifestyle. It’s not like, ‘I’m on a diet.’ I’m working towards having a healthy lifestyle.”

In the same interview, Savannah admitted that she’s struggled with body image in the past. “There are a lot of times I let it get in my head,” she said. “That starts to have an impact on how I think about myself. But recently, I’m embracing what I’m seeing. I don’t look at a number, I don’t step on a scale. It’s just about how I feel.”

Savannah said her fiancé is also trying to eat healthier. “We’ve kind of made a pact,” she said of Nic. “We’re going to keep each other accountable and have a healthy lifestyle.”

Savannah and Nic haven’t set a date for their wedding yet, but you can definitely count on one thing: She’s bound to look great in her wedding dress.
