Interesting discussion. I think it's worth remembering that Oprah is an extremely ambitious and marketing-minded celebrity, above all else. In some ways, as has been pointed out in this thread, she has changed her message to match the prevailing marketing/sponsorship opportunities. Pardon me if that sounds cynical, but I know from way back that she's had her eyes on the prize of remaining influential and relevant, and this WW partnership is one more step along the way. I like many of her messages of self-acceptance and the strength of women and minorities, but I'm sure all of these things are carefully molded to her public persona and Oprah as a brand and tastemaker.
Ok, on to the topic of weight loss and image enhancement as the primary goal of "self-improvement"... absolutely I agree that hyper-focusing on these things is a sure way to be unhappy.
Example. There is a woman in the resort where I am currently staying. Very slim, very tan. Posture is impeccable. Obvious but clearly quality boob job. Long, carefully styled and very expensively colored blonde hair. Perfect white resort wardrobe. At first glance, you think this woman is in her 30s, until you see her face. Again, immaculate makeup but it becomes quite obvious up close that she is likely in her 60s. Ok, I've got no problem with any of this, right? It's clearly her prerogative to "take care of herself" in whatever ways she sees fit. The thing that strikes me, however, is that she looks miserable. She doesn't strip down to her swimsuit and jump in the water. I haven't seen her smile or laugh with her husband. She is in a beautiful place, is an attractive woman, presumably with the love of her life, and presumably with enough money to be vacationing in quite a nice place and in high style, but she just looks so unhappy. I can't help but wonder what her pursuit of physical perfection has gotten her.
Meanwhile, my pasty white, cellulite-thighs and I are having a blast. Yes, I've been working out walking or running for at least 45 minutes each day, but I've also been going without makeup and eating guacamole and drinking margaritas every day too. I'd rather be physically imperfect and enjoy myself!
