"Strict" Keto Gave Vicki Gunvalson's Daughter Briana Culberson a Whole New Look — See Dramatic Before-and-After Pics

We already know that Vicki Gunvalson's daughter, Briana Culberson, is the "Keto queen." Late last year, her husband, Ryan Culberson, used his Instgaram feed to share that he was "so proud of Briana my keto queen! It has been such a easy transition for us over the last 5 months."

And now The Real Housewives of Orange County son-in-law has a new Instagram post showing his wife's progress — and sharing effusively just what keto has done for her (and for him, too).

The post showed side-by-side before-and-after pics — with the one on the right showing a slimmer physique and glowing skin.

The caption read: "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! For more info the link is on my profile page bio."

Following the caption were hashtags like "ketotransformation" and "ketolifestyle" — plus "whatareyouwaitingfor."  

Overall, celebs tend to have strong feelings — and choose unequivocal sides — when it comes to the controversial Keto diet. Here’s what some of the most vocal fans and opponents have had to say:
