[Diver Down]

I'm on my third attempt with Atkins and my weight loss during this induction phase is the most severe of them all: I've lost 11-13 pounds in just 6 days. Typically, my weight loss during the other two inductions (roughly) followed a pattern of losing 10 pounds in 10 days, 18 pounds in 18 days...which is still rather extreme, but nowhere near what I'm going through now. I'm starting from a much heavier weight this time around; could that be part of the reason? In any event, is this type of rapid weight loss something I should be concerned about? I'm eating steadily, plenty of meats and cheeses, but maintaining a very low carb intake. I'm even drinking diet sodas with caffeine, sodium, and aspartame. Not to mention having some carb bars and low carb ice cream treats along the way. Why am I losing weight at this pace, even doing things which are known to slow weight loss? I love the results, don't get me wrong, but I'm a little concerned and mostly just terribly confused. I can't explain the cause and I'm really looking for some kind of explanation since it's beyond my realm of understanding.
