Vicki Gunvalson's daughter Briana Culberson and son-in-law Ryan Culberson recently announced they've lost a jaw-dropping combined total of 107 pounds on the Keto diet, which they've followed devotedly (save some necessary cheat days) for about a year now.

The Real Housewives of Orange County couple hasn't even found it that difficult to do, to hear Ryan tell it on his Instagram, which is filled with satisfying-looking foods and Keto recipes.

One of Ryan's most recent Keto recipe shares is one for "The Best Keto Meatloaf Muffins" — which call for a prep time of just five minutes. 

The whole ingredient list is 10 items — and those include salt, pepper, ketchup, and other spices you're likely to have already in your cupboard. 

The recipe claims these "savory fat bombs" are "ideal for Keto meal prep lunches."
