I've been on a low carb/high protein diet for the past 2 weeks. Surgery is on Wednesday. I've been on vacation for the past 9 days but know that I have done well with my eating because some shorts that were too tight on me when I started the diet are now completely loose. Yet the morning when I weighed myself I hadn't lost any weight. Why is this?

Did you weigh on the same scale at the same time of day with the same amount of clothing on?

yes- I always weigh first thing in the morning with no clothes on.

I did think back and realized that I didn't drink enough Water. So I may be retaining some water too. I know whats really important is the liver shrinkage but its still discouraging to know you did pretty well and feel like you have lost weight but the scale doesnt move.

It is discouraging but I bet if you up your water intake you'll see results fast!
