"I can honestly tell you I struggle no more," a healthy and happy Oprah says, whom the camera captures practicing yoga. "I live well while losing weight. It is easier than it's ever been."
ET spoke to Oprah about her goal weight in July, when she said that she actually didn't have a particular number on the scale in mind.
