Ok. @MissPennyP:
First, instructions from teams vary greatly from one person to another. I would always tend to say to listen to your team, but to also supplement this with asking them questions, and doing your research (not just on public forums, but also from the gazillion studies and article published out there on the good ol' internet).
I will admit that your prescribed diet does sound very different from the majority of what I have read here and elsewhere.
HOWEVER, there was one fella on here on here who was also prescribed a similar diet to yours this early on and self-reported some significant success (I can't remember his handle name, and he recently announced that he was no longer participating on this board...which I suspect was partly due to the flack he was getting about his diet, but I digress...).
If you are sticking to under 700 cals are day, you will lose weight. Not as fast as those who did 300-400 in the early months (myself included), but you will lose.
You are barley a month out of surgery, stick to your a low cal (preferably low carb as well) and keep going. Continue to stay honest with yourself with what you are eating and what you are doing and you will see the weight come off. Get some exercise and move, that will help too. Speak to your team and let them know your concerns. Do your research. Make informed decisions.
You will get out of this surgery what you put into it. Good Luck!!
