I like cabbage soup, and keep some in the freezer, for days, when I've had all my good food and need a snack. It is a good low cal, healthy option.
However, it's not a lifestyle or plan. One can not live on cabbage soup alone.
Our bodies need more than cabbage/veggie soup.
I understand why you don't want to *settle* for the dress, however, in the long run, you will be happier, if you find a good balance of healthy nutrition, exercise and the now and then cake or drink or what ever, that you can sustain for life.
