I have Gallops book also I like the concept of the green light foods list and I have been back and forth on the Atkins they don't know what caused my issue I just had (it's in my journal) but I felt the same way the last time I did Atkins and that feeling never went away until I stopped eating a high concentration of fat. Which is a RED light in gallops book. The doc says they don't know what causes what I had nor how to prevent it. So I have decided to try the low GI again just to see - it's generally low carb.
So when are you starting again? Do you have any mini goals yet? I don't get on here very much but I will check in on you when I do.
Good luck with your fresh start
