Oprah Winfrey shows off her amazingly slim waist in an orange outfit while out in Hollywood.

The 70-year-old talk show mogul, whose weight has fluctuated over the years, has begun taping Jimmy Kimmel Live!.

Currently, she is causing a stir in public opinion for her upcoming documentary about people who use weight loss pills.

After being trailed by rumors that she was on Ozempic, Oprah herself admitted last year that she has fallen back on medication to shed the pounds.

During her latest public appearance, she flaunted the results of the treatments in a skintight sweater worn under a crop turtleneck.

As she headed into the studio, Oprah joyfully flung her arms in the air, causing her crop top to ride up and emphasizing her reduced frame.

Her talk show appearance come four days before the ABC premiere of her documentary An Oprah Special: Shame, Blame and the Weight Loss Revolution.

Oprah will interview people who have used popular weight loss drugs like Ozempic and Wegovy, as well as professionals with experience in the field.

‘It is a very personal topic for me,’ said Oprah in a press statement quoted by BET:  ‘and for the hundreds of millions of people impacted around the globe who have for years struggled with weight and obesity.’

Over the decades of her superstardom, Oprah has been candid with her fans about the various steps she has taken to lose weight.

Last year she was dogged by rumors she was on Ozempic, the diabetes medicine that has become a Hollywood fad among those attempting to slim down.

As the speculation mounted, Oprah confessed in December that she had relented and started taking weight loss medication – after previously feeling that she had to rely on her own ‘willpower’ to achieve the figure she wanted.

Her size ‘occupied five decades of space in my brain, yo-yoing and feeling like why can’t I just conquer this thing, believing willpower was my failing,’ she told People.

When she underwent knee surgery in 2021, her physical rehabilitation helped her develop a number of healthy habits that helped her burn fat.

‘After knee surgery, I started hiking and setting new distance goals each week. I could eventually hike three to five miles every day and a 10-mile straight-up hike on weekends. I felt stronger, more fit and more alive than I’d felt in years,’ she gushed.

‘I eat my last meal at 4 o’clock, drink a gallon of water a day, and use the Weight Watchers principles of counting points,’ added the television icon, who at that point was still on the board of directors of Weight Watchers.

As for the drugs, she said: ‘I had an awareness of medications, but felt I had to prove I had the willpower to do it. I now no longer feel that way.’
