Kelly Osbournes dramatic weight loss due to lifestyle changes drew in intense online scrutiny. Here are the factors that contributed to her changed physique.
Singer, actress, and fashion designer, Kelly Osbourne, is the daughter of the legendary artist, Ozzy Osbourne. On February 28, 2026, Kelly and her mother, Sharon Osbourne, attended the BRIT Awards at Co-op Live in Manchester to accept a posthumous Lifetime Achievement Award for the late Ozzy Osbourne, who passed away in July 2025. Following her appearances at the BRIT Awards and earlier events such as the 2026 Grammys, Kelly has faced intense body-shaming. She fiercely defended her slender physique against abusive online comments. Amid that, here is a look at the reason for her drastic weight loss.
Kelly Osbourne has recently slammed the commentors on her weight, describing the trolling as “disgusting”. One online user even went as far as to compare Kelly’s physique with that of a dead body. “Looks like a dead body... She’s tooooo thin and fragile... Looks like she’s going to see her dad soon,” they wrote. Another commentator sarcastically stated, “You seem to be carrying a lot of jealousy and envy around, literally and figuratively.” The 41-year-old, Kelly, shared a screenshot of such abusive, defaming, and body-shaming comments and wished no one would have to go through something like that. Taking to her Instagram Stories, the internet personality wrote:
“Literally can’t believe how disgusting some human beings truly are! No one deserves this sort of abuse!”
Kelly Osbourne’s weight loss journey has been a decade-long process involving medical procedures, lifestyle changes, and major life events. Following her appearance on Dancing with the Stars, she lost nearly 20 pounds through daily cardio and dietary shifts. Kelly became even slimmer after a sleeve gastrectomy (gastric sleeve). She revealed in 2020 that the surgery resulted in 85 pounds of weight loss. Kelly described the procedure as a “tool” that gave her a “fighting chance” rather than a quick fix, noting that it required at least a year of therapy to prepare her mindset.
During her 2022 pregnancy with son, Sidney, Kelly Osbourne gained approximately 100 pounds, which she revealed on Scheananigans podcast. She was diagnosed with gestational diabetes, which added to her rapid weight gain despite not eating much. After giving birth, she was determined to lose weight, which forced her to adopt a strict sugar-free and low-carb diet to manage the condition. She admitted that she pushed herself too hard at that time. Her exact words were:
“I was on a mission after having the baby…I went a little bit too far [with dieting], but I stopped.”
Following Kelly’s public appearances in late 2025 and early 2026, social media users frequently used the term “Ozempic face” to describe her noticeably thinner and sharper facial features. However, experts note that such changes can occur from any rapid weight loss, including that caused by grief or surgery. Kelly has repeatedly denied using Ozempic for her recent weight loss. She attributed her most recent weight loss to the death of her father, Ozzy Osbourne, in July 2025. Her mother, Sharon Osbourne, supported the statement, saying that Kelly has been “struggling to eat” while mourning. Sharon said:
"She's not happy, she lost her daddy. She can't eat right now. [The internet] is a shield for people who are unhappy. Jealousy and people's perception of somebody else — how many times have we been wrong about somebody because of our perception? A lot of effort goes into [hurtful comments]. I feel sorry for people. There's something wrong with their lives. They're not happy."
