I'm on a similar plan. I have about 50-70 grams of carb a day and then on Saturday, I have what I want for lunch minus grains. Never any grains. I don't dare do the same on Sunday because that will set me back.

I did this years ago, intending to maintain, but didn't when life got in the way (again). This time, trying to find a way to eat that I can do for life.
