Atkins implies that it's your decision whether or not to start adding more carbs. It depends how much you care about slowing down your loss. I stayed on induction for almost a month, mainly because I felt very comfortable there. Of course, if you are looking for more variety, adding five or so grams of carbs feels quite good. I started eating cottage cheese, nuts, and even a bowl of strawberries and cream! And still gradually losing, so I'm satisfied. If you want to melt off a few more pounds quickly, it's safe to stay on induction levels another week or two, but if you want more yummy foods, go ahead and start adding. Whatever works for you.

Congrats on the initial loss. But I agree, the way it makes me feel is ten times better than anything weight related.

Happy low carbing!
