Since Briana Culberson and her husband Ryan Culberson committed to the Keto diet about a year ago, they've lost a whopping 112 pounds combined — according to the latest update from Briana's mom, Vicki Gunvalson.
The Real Housewives of Orange County couple has been outspoken about their deep devotion to Keto on social media — but is it only Keto that made the difference for them, or a larger lifestyle overhaul including exercise as well? Ryan recently answered that question, in response to an Instagram commenter.
The follower asked, "Does Briana work out also? Or is this all from Keto? She looks amazing!"
Ryan responded, "No we haven't started incorporating working out. We just focus on the food."
Here's what celebs have said about the controversial Keto diet, good and bad:
