Well I am two weeks out and not losing weight...actually gaining. I got dehydrated first week so that may be why I lost 10 pounds first week but now I am up 5 pounds and this week I start pureed today. What is wrong? Why am I not losing?

You are fine. around week 2-3 you end up hitting the infamous 3rd week stall where you wont loose and can gain. and this will happen throughout your first year. your body is adjusting. just stick to the plan

liveaboard15 is correct. Most of us experience the "three week stall". Also, those weight fluctuations are just fluctuating water levels. With as little as you're probably eating, there's no way that's a true gain. It's just fluid levels.

Echoing what Liveabord and Catwoman said! I got a smart scale from Amazon. Very helpful for those weeks when the number on the scale doesn't change, but maybe your bone or muscle mass increased and fat went down. Or your water weight increases, mine is still low post op. Also, from previously tracking my many diet attempts, it was never in a smooth linear line. One particularly regimented diet that I followed religiously, I lost 3 lbs every 3 weeks. Not a pound a week, but literally nothing for 2 weeks, then 3 lbs. It followed that pattern for 5 months until I stopped.
