Challenge to eat enough calories and protein

MDs and NUTs vary in their advice.  Many docs suggest 800 calories, so does my NUT.

I stuck to 600 calories and never had a plateau.

My MD was ok with me being around 600 but I started to feel very sick when I kicked into gear my exercising--didn't you feel weak exercising at that level?

I have heard that they eat about 600 cals on the Biggest Loser (in the beginning at least), and they work out like mad fiends, but they are intensely supervised. 

I had to up mine around 800 and I am still stuck for a week now and very, very frustrated trying to find my optimum caloric level to get the scale moving.  I normally don't have issues with losing as much as keeping it off, so I don't know what to do next.  Today I am trying to drink even more water, I already drink between 64-80 a day, plus coffee (black w splenda) in the a.m.

The daily plate says I should eat 1100 but that feels high (and hard to get in unless I eat high fat foods which is not a road I want to walk down!)

No solids for me for another two weeks, on soft diet.  I am allowed chicken and tuna and lunchmeat in this phase to help get protein.  They want no shakes at this point if I can get it in my own.  Since you posted such a low #, I was curious how you felt exercising at that level.  I was a 22/24 at the beginning of my journey, and currently an 18.  I don't do plateaus!

I think you are at the optimum level of restriction. The goal is not to be hungry and to stay within the protein-calorie guidelines.  You don't have to be tight, stuck, pb'ing or whatever to have "optimum restriction".  it sounds like you allready are there. Congratulations.

Thank you, thank you, thank you to everyone *****sponded and for providing all of the good advice.  I have a lot to learn, and it's great to hear various perspectives.
