Oprah has always said that when she gains weight, it means that something in her or her life is out of balance, and that is what she has always passed on...getting your life to be in balance.
I do believe I've heard her say that. I feel the same way about myself.
Therefore, you probably mean that you're sad for her if she feels ashamed...she might very well feel that way, I know I do when I'm in an upswing. In fact I've finally stopped lying to myself about my weight, stepped on scales, now I have a goal, I'm working out...because of the weight I've let myself put on, I feel ashamed.
But I surely wouldn't want people to say that it's shameful that I gained.
Then again, if someone just said "it's a shame", I'd agree, if they were talking about me. I'm quite cute when not too heavy, and quite NOT cute when heavy...so it is indeed "a shame" when I gain.
Of course, Oprah doesn't "lose her face" when she gains, she's always quite pretty, so maybe she doesn't feel that way about herself!
So many words with "shame", and the one chosen was the one that sounded like a slam. The others aren't as bad, and might very well be how she's feeling about her weight. Maybe.
Anyway, I would imagine she's just tired...I know I would be!
