Hi Crystal, well done on your weight loss so far!
Right, first thing to say - Chele80's right - average weight loss on this diet is 3 to 4 pounds a week (depending on how much you have to lose - the heavier you are to start with, the more this is likely to be in the beginning).
But that doesn't mean that those 3-4 pounds lost will always show up on the scales.
Now, rest assured, if you've been 100% (and IMHO, I don't think a tiny bit of milk makes a lot of difference), you'll be losing 3-4 pounds of
fat a week.
Unfortunately, for various reasons how much
water your body is holding on to fluctuates all over the place - it can be affected by being a bit under the weather, being stressed, being hormonal - you get the picture. And water weight still shows up on the scales - they can't tell the difference, you see.
So that's why some weeks (after the first week), you'll lose 6 pounds one week and 1 pound the next. Over the course of a month, you can expect to lose a stone. Unfortunately, it's really unlikely it'll come off in even amounts each week.
Oh, and on this diet, funny things can happen. The scales may stay the same for 5 or 6 days at a time - and then all of a sudden, overnight you can drop 2 or even 3 pounds (that's the water suddenly dropping off). Ah, it's all good fun.
Let us know how you get on, okay?
