I just started my 5th week of Atkins.

After measuring and weighing over the past 4 weeks I noticed some interesting trends. When I lost weight over one week, I didn't lose considerable inches, but when I didn't lose weight over another week, I did lose considerable inches. E.g., last week, I didn't lose any weight, but I lost 1 inch from both my chest and my waist.

Is this typical? If I am losing weight, but not inches, what did I just lose? If I am losing inches, I would assume that I am losing fat, but then why doesn't it show up on the scale, or maybe a better question would be what is taking the fat's place?

Anyone have experience with this?
