I started at a BMI of 32 and I'm 4 weeks post op and have only lost 7 lbs - after surgery. (I gained 5 after surgery and took over a week to lose that gain). I'm discouraged. Yeah I know it's going down instead of up and I should be grateful. But I just can't understand how I can barely consume 500 calories a day and not lose more weight even after adding more walking and light weights. I've done diets before surgery and have lost more weight in less time. I'm totally confused:(

Well, the weight you "gained" after surgery was post-op fluids from IVs and swelling, it wasn't really a "gain." Next, you've got a low BMI to start with, so your loss isn't going to be as dramatic as someone who starts off with a higher BMI. Finally, sometimes you have to increase calories in order to lose or else your body thinks its in starvation mode.

Always eat protein first
