Talk show queen Oprah Winfrey regrets exhibiting a wagon-load of fat on her US TV show to signify her 31-kilogram (67 pounds) weightloss in 1988 - because she put much of the weight back on.

The 51-year-old star, who celebrated THE OPRAH WINFREY SHOW's 20th anniversary on Monday (14NOV05), regards the infamous episode as one of her biggest mistakes.

She says, "I had literally starved myself for four months - not a morsel of food.

"Two hours after that show I started eating to celebrate - of course, within two days those jeans no longer fit!"
