Taco Bell Diet?

Subway had enormous success with the release of their diet-branded campaign promoting healthy alternatives with spokesperson Jared - who really did drop all those pounds by eating the low fat subs daily over a long period of time.  So how serious is Taco Bell really being with their new campaign for the Drive-Thru Diet? 
In comparison, the campaign follows the same overall strategy of a diet-branded campaign, by having a spokesperson, Christine Dougherty, claiming to have lost 54 pounds over 2 years by eating off of Taco Bell’s Fresco Menu.  But what separates this campaign from that of Subway, is that Taco Bell’s entire campaign holds a strong sense of parody to it.  Their online website includes infomercials of her story and uses language that doesn’t exactly suggest credibility.  The question being asked when the spokesperson claims that she wanted to diet but, “didn’t want to cut out my fast food” is - Pardon me, can you repeat that?  That’s like saying, “I want to quit drinking, but don’t want to cut out my brandy,” or even, “I want to save money, but don’t want to cut out my shopping.” 
While some nutritionist are up in arms over this campaign and how it is having an effect on the nation, which is definitely something to consider, I have a feeling most consumers are reading into the suggestive parody and laughing along.  Fast food restaurants have been trying to keep up with the trends of offering healthier alternatives these past years, and while the angle is somewhat questionable, the Fresco Menu is currently all Taco Bell has to offer consumers looking for something healthier.
What do you think of the new campaign?
