Briana And Ryan Culberson Just Shared A Photo Of Their 128-Pound Weight Loss

© Instagram Briana Culberson, daughter of The Real Housewives of Orange County's Vicki Gunvalson, and her husband Ryan Culberson are practically spokespeople for the keto diet. The two have been steadily documenting their keto-fueled weight loss—and Ryan just shared another update on Instagram.

"Smiles from a couple that's down a combined 128 pounds!" he captioned a sweet photo of the couple posing together in the woods. "No fads, workouts, or magic pills just a consistent Keto lifestyle!"

Ryan and Briana first talked about doing keto in November 2018, when Ryan referred to Briana as a "keto queen" on Instagram. He noted that they'd been on the diet for five months at that point.

Fast forward to January 2019, and Briana posted on Ryan's Instagram that she'd lost 45 pounds on the diet. She also said that keto "greatly improved" her health. (Briana was diagnosed with lupus in 2016 and almost had to have her leg amputated in 2018 due to her condition, according to People.)

In March 2019, the couple revealed on Instagram that they lost 86 pounds together in eight months on the diet. "Celebrating being 86 pounds lighter between the two of us!" he captioned the shot. "What are you waiting for?"

And in July, the two shared that they were 107 pounds lighter on keto. "Happy 4th of July from my family to yours!" Ryan captioned a shot of himself, Brianna, their kids, and her stepfather Donn. "Swipe right and see the difference a year on keto has made, down 107 between the two of us!"

Ryan and Briana have also offered up little snippets of advice here and there including how it's possible to stay on the keto diet at Disneyland (JIC you were wondering… ).

So, yeah, they're now an amazing 128 pounds down. It's not hard to see why they're into keto.
