I think you did fine on Induction if you ate the guacamole & fajitas. (no tortillas & no chips)
Atkins allows extra "special foods" every day and 2 of the 4 ingredients in guacamole are in this catagory. 1/2 avacado & lemon juice. Add a tiny bit of tomato (less than a slice for a serving) as well as a tiny amount of garlic and you have guacamole. Both tomato & garlic are on the acceptable list for Induction. I advise you to get Dr Atkins New Diet Revolution or go to the website. They both have lists of acceptable foods for each phase.

I only stayed on Induction for a week ( though I tried for 2 weeks) but I added nuts after the first week so technically Induction for me only lasted a week.(though I kept my carbs below 20 for 3 weeks) I figured that a week of Induction was good since I was in ketosis and if I didnt have more than the strictest level of Atkins I probably wouldnt keep on with it. I figured I'd rather lose slowly than not to lose at all.

Good luck & keep on keeping on.
