I have not lost a lot of weight on EE - 11 pounds in 12 weeks but I have all my syns each week and have gone over a couple of weeks with flexi syns!
I don't feel deprived in anyway, and feel fuller and am enjoying my food much more than before I did SW!
I am happy with the loss as it's in the right direction.
I have done mixtures of red and green and lost similar amounts, or less perhaps. I think I cheated more then and probably did EE before it was even brought in!
I, personally find doing either green or red a bit restrictive, for me. I know that others do well on it, but I prefer EE.
