Hi itsjustme and darbs! welcome to you both!!
itsjustme - I'd echo claire in saying that you can do Induction, but once you have 10lb left to lose it is integral to move to OWL. The OWL process is where we learn to make Atkins sustainable. Induction is not sustainable. OWL teaches us how our bodies respond to different foods and different carb sources so we can determine what will lead us back to food cravings that will get us back into trouble later. Atkins says that you should count on spending a long time losing the last 10lb, because your losses are going to slow down significantly as you up your carbs. This can be frustrating but it is so, so important to go through this process!! Also as claire said if you find yourself too close to your goal weight and still on the first rungs of OWL, start adding carbs back by 10g every week or two until you find your CCLM. Once you have your CCLM you can back off by 5 or 10g carbs and lose the rest of your weight while adding in new foods. HTH
darbs - Eep, 800 calories!! Phew. That must have taken some willpower!! On Atkins we do not count calories, we focus on our macronutrient ratio. Aim for 65% of your cals from fat at a minimum. Since you have been basically on an extended induction period, go ahead and move to OWL, so you can learn how to happily be carb-conscious for life. Do you know how OWL works? You add carbs back in 5g (NET carbs) increments, as quickly as 5g/week or slower than that, as you wish. First, you add them in vegetable carbs from the accepted induction veg list. So you can eat a max 25 NET carbs per day. You continue gradually adding carbs in 5g (or 10g if you have very little weight to lose and your losses are still quick) increments until you find your CCLM - the number of carbs per day you can eat and *maintain* your weight. Once you have a week or two with no weight loss (or a small gain), you know that you just have to eat fewer than that number of carbs to lose! How cool is it to have that number with no guesswork! As you are adding carbs you also go through 'rungs' of the OWL ladder, allowing you to add in fruit, nuts, dairy, grains, starchy veg, alcohol, and other food items you are currently restricting. Do it slowly, though, to watch how your body reacts to each, and stick to your carb limit!!
Whew, didn't intend to write a novel... I am in a chatty mood

hope that helps you guys!
