I've done the Suzanne Sommers diet for about 4-5 years and have really liked it. It eliminates the bad carbs (white flour, sugars) while being able to eat the good carbs (whole wheat, brown rice).
I am addicted to pasta, so could not think of giving up carbs all together.
It has been an easy one for me to stick to, plus I feel a lot healthier. My fiance is pre-diabetic, and so it works well for him also.
