Need advice about food portions and such

I said the same thing to my nurse at my appt today.  She said to email or call them anytime for support.

 Eat between 500-700 cals.  The 40-30-30 that I used was 40%protein, 30%carbs, 30%fat.  But really, if you are eating so little, the main thing to focus on is getting the minimum of 60g protein.  
Use fitday.com or myfitnesspal.com to track your food.  Around 6 months out you should increase your cals to the 600-800 range.  If you are very active, the NUT might suggest 1000 cals a day. 

The rest of the rules that I have followed...

Eat protein first, then veggies/fruits if you have room, grains last.
A meal should never be more than a cup of food (although this is for those farther out...you are probably eating much less)
Separate your fluids and meals by 30 minutes each side
Don't eat more than every 2 hours.
Eat at least every 5 hours

This is just what I have done, I'm sure there are many variations.  You are probably doing just fine as long as you are hitting your protein and water targets.  

I aimed for 90g protein, 64 oz water.  Nothing else mattered at the time.

 I had my one month check up at TWH with the nurse yesterday.  I was asking her questions regarding food and she informed me that we should have a nut appointment at one month as well.  I was lucky and the nut had a few minutes to see me.  I was advised that we should be having 60-80g of protein.

What about fibre...you know...so things come out okay in the 'end'?
