How much were you expecting to have lost? Remember that your bodyweight will vary by a couple of pounds, sometimes more, over the course of a day; unless you can guarantee to always way yourself while your bowls are empty and your hydration level is absolutely perfect, you're going to see a variation from day to day. Sometimes that variation will mask your weight loss (e.g. you lost half a pound of bodymass but you ate a curry which really isn't shifting yet).
