Why is the Cabbage Soup Diet Still Around?

One of my friends is trying to lose weight fast because she's a size 14 and she bought a size 10 dress to wear to her high school reunion. She's kind of a "last minute" sort of person so of course she waited until one month before the reunion to do that losing 20lbs fast thing.

She's had 6-months to knock off the weight through diet changes and exercise, but now we're at DEFCON-4 for fitting into the very pretty and expensive dress she bought and I asked her what she was going to do. Her solution? Why the Cabbage Soup Diet of course.
I admit it, I snickered. Audibly.
And she said, "Oh it's been redone and revamped. It's not the same. A nutritionist redid it."

I said nothing. The Cabbage Soup Diet is one of the worst offenders in the Fad Diet category. No nutritionist in their right mind would ever recommend consuming the Cabbage Soup Diet as an alternative to eating sensibly and exercising as a weight loss plan. Sure it's low in calories but it's also low in nutrition and my friend may very well lose the promised 10-15 pounds, but the problem is that most of the weight lost will be primarily from fluids, not fat, and will return quickly once she resumes eating normally.

So, it's now one week until reunion time, and I checked on my friend to see how she's doing. She got bored with the Cabbage Soup diet around the "eat 8 bananas day" part and quit. She bought a larger sized dress and and a gym membership the same day. So at least she's on the road to getting a healthy lifestyle going without the Cabbage Soup Diet.
