Wynonna Judd is singing the weight loss blues ... or rather the reds, blues, golds and greens of the alli© logo. She's signed on as spokesperson for the weight loss drug.

Judd is part of a long-list of celebs who have lent their names and faces to weight loss products. Jenny McCarthy once touted Weight Watchers, and Phylicia Rashad is the latest celeb speaking for Jenny Craig. Regarding alli, Judd said "I've considered every diet under the sun, but so many of them wanted me to be something I'm not and do things I knew were not healthy for me. Then I discovered alli. With the alli program, I'm learning how to make and maintain healthier lifestyle choices. It keeps me honest with myself and allows me to set realistic goals."

That's great, Wynonna. But I've got one question. Why do you need alli to do all that? You can make healthier choices and set realistic goals without a pill. An over-the-counter version of Xenical, alli can have some unpleasant side effects. It works by blocking up to 25 percent of fat from being digested. Without getting too graphic, that can lead to some unexpected (ahem) leakage.

So, Wynonna, I wish you the best of luck in your weight loss journey. And I hope that you have plenty of dark pants in your closet to help you avoid potential embarrassment should things get a little messy.

If, like Wynonna, you want to make healthier lifestyle choices and set realistic goals but would prefer to do so without the aid of an adult diaper, check out the America On the Move: Shrink a Size program.
