Yes, Margalo, quite detrimental. Atkins is a Low Carb plan, not a no carb one. You need some carbs and you definitely need the fiber and micronutrients that vegetables will provide. I strongly suggest pulling out your copy of DANDR and rereading the chapter(s) on induction. Dr. Atkins provides a detailed list of the foods you must eat and the ones you should eat. Veggies, leaner cuts of meats (such as those I listed above), cheeses and various fats are all listed.

If LCing is to be a WOL (way of life) then it must be something that you can do over the longterm. Eating just hamburger and salami isnt something you can do for the rest of your life. Reading through some of the members' journals will give you a better idea of what you need to eat. Re-reading Atkins, however, is key.
