I have been babystepping into low carb, starting with the Insulin Resistance Diet and Life Without Bread. Now I think I am going to move on to Protein Power.

I am about halfway through the book (the earlier one from the mid-'90s) and I have a couple questions about supplementation. Should I expect to need a potassium supplement at the 55 carb level or only if I drop to the full 30 carb limit? If I need it, what is the best source of potassium?

I suspect I will need to use some sort of protein powder or other supplement to reach 65 grams a day, especially since I eat two meals a day at my desk. What do you recommend? I like the Atkins shakes just fine, but am open to other, simpler things. Does anyone use spirulina?

Thanks for any help.
