Hard work is paying off for Daphne Oz.

Oz revealed she's lost “nearly 50 lbs.” since starting her health journey and becoming a WW ambassador.

“I still have a way to go, but my aim to feel strong in my skin, energetic for my kids and to love the way my clothes fit have been my guide,” she wrote on Instagram alongside a mirror selfie.

“I’ve had these goals in the back of my mind throughout the upheaval and stress of the past few months, because historically for me it would have been such an easy way to slip back into old emotional eating habits,” she said of staying healthy during the coronavirus quarantine.

Back in February, Oz told People magazine her fourth pregnancy was the “hardest pregnancy, physically" on her and she was ready to make “meaningful eating choices.”

Since the quarantine began, Oz has been homeschooling her three older children: Philomena, 6, Jovan, 4, and Domenica, 3, with her husband, John, creating new recipes and getting in a workout whenever possible.

"We have a million Zoom meetings and the house feels extra chaotic at times. But we bake a cake every Friday. We build forts and don't clean them up right away. My kids have me crafting (I am not a crafter)," she said.

Oz added: "We do elaborate treasure hunts around the house. We do lots of movie nights and read extra books before bed. My hope is that these are the moments we are all going to remember."
