'RHOC' star Vicki Gunvalson's daughter Briana loses 45 pounds on keto diet

Real Housewives of Orange County” star Vicki Gunvalson’s daughter is reaping the benefits of a keto diet.

Briana Culberson’s husband, Ryan Culberson, posted a side-by-side comparison of her, seemingly captioning it from her viewpoint: “The face on the left is of an average American diet, never felt good, having constant lupus flares, and on and off steroids for almost a year. The face on the right is strict Keto, steroid free, and lupus flare free! I’ve lost 45 lbs on keto so far but most importantly my health has greatly improved!”

Ryan has been chronicling the couple’s journey with the keto diet on his page, as Briana maintains a more private lifestyle.

Briana, 31, first revealed she was diagnosed with lupus during the “RHOC” Season 11 finale in 2011. Gunvalson, 56, revealed in 2017 that Briana “almost died” due to a surgeon using a dirty scalpel. It was unclear what she was receiving treatment for at the time.

She was most recently hospitalized in April 2018 for lupus-related ailments.

“Please keep my wife in your thoughts and prayers! Her lupus is causing inflammation around her heart and is causing it to go in and out of irregular heart rhythms now requiring her to have a cardiac ablation,” Ryan posted ahead of her hospital stay.
