I have been doing this WOL for almost a year now. I know I can stay with it forever. I losing very slowly, but as I plan to eat like this for the rest of my life, it doesn't really make any difference how fast I lose the weight. My blood sugar is under really good control, as is the rest of my health. I have no problems staying at 20 -25 carbs. I enjoy the foods I eat and I'm not feeling deprived in any way.
