The married couple have credited the popular keto diet with helping them shed the pounds.
Briana, 32, gave her hubby a grocery list on Thursday that was very keto-friendly.
"She's trusting me with a list!" Ryan wrote on his Instagram story. "I'm honored!"
Items on her Costco shopping list included 2 packs of salami and a tub of cherry tomatoes, all of which are good with a keto diet.
She also included household supplies for him to pick up like dog food and batteries.
Ryan and Briana showed off the 107-pound combined weight loss on Instagram on Thursday, July 4.
Their fitness journey could be featured on RHOC's upcoming 14th season. Her mother Vicki Gunvalson confirmed that Briana will be returning after exiting the show two years ago.
