Pregnant Kelly Osbourne loses 10 pounds after gestational diabetes diagnosis

Kelly Osbourne has lost 10 pounds since being diagnosed with gestational diabetes in the third trimester of her pregnancy.

The “Osbournes” alum told People in an interview published Thursday that she initially thought she had “done something wrong” when she noticed her rapid weight gain, unusual fatigue and ankle swelling.

After the actress, 37, was diagnosed with the condition, which is when a pregnant person’s body is unable to make enough insulin, the expectant star decided to cut sugar out of her diet.

“I wasn’t eating right [before],” the “Fashion Police” alum explained to the outlet, noting that her only craving was sugary juice.

Since changing her eating habits, Osbourne has lost 10 pounds and cleared up her skin.

“I haven’t had to wear compression socks once since I cut the sugar out, which is unreal for pregnancy,” the former reality star added. “I just have more energy. I’m sleeping better.

“You don’t realize what it’s doing to you until you take it away is all I can say,” she continued.

Osbourne went on to call her pregnancy the perfect “incentive” to make such a drastic change.

“I’ve never been able to stick to anything a hundred percent the way that I have been doing this because I’m not doing it for myself,” she explained. “I’m doing it for my baby.”

Osbourne revealed in May that she is expecting her and Sid Wilson’s first child, gushing to her Instagram followers about how “ecstatic” she is.

Carrying the little one has been the “roughest, most weirdest, wildest” experience, Osbourne told Jada Pinkett Smith and Adrienne Banfield Norris on Wednesday’s “Red Table Talk” episode.

Osbourne noted that she isn’t planning to breastfeed her upcoming arrival as she wants to stay on her medication.

“The judgment that I have received from my friends and also extended family [is wild],” she said, adding that she “can’t pay attention” to negative commentary because her choice is “best” for her family.
