Sorry to respond to this so late. I just signed up to this site yesterday.
I'm currently using this system and am quite impressed by the results. So far, I have lost 23 lbs in a month. What is more important is that I haven't "cheated" or fallen off of this eating plan like I ALWAYS did before. I see no reason why I cannot do this for the rest of my life. I still eat all of the foods that I like, and I eat until I am full.
What I have noticed is that not only do I eat less, because I am eating consciously, but I am eating differently. For example, I used to devour those big Hershey chocolate bars. However, over the past month I ate one sixth of a single bar once. For whatever reasons, my tastes have shifted dramatically, and some of the more extreme foods (meaning extremely sweet or salty) that I loved before no longer hold the appeal that it did before.
If anyone has other questions, I will answer to the best of my ability.
