How much is too much

I am a little over 10 weeks out my dietician said by 12 weeks I should be eating about 6oz of food per meal...I am only at about 4oz but beside that i am wondering if there is a certain number of calories I should be taking in.. I average about 1000 cals and 75-90g of protien I also workout 3-4x per week burning about 500 cals per session..Iin general I have 3 main melas B, L, and D and then a morning and afternoon snack---snack are mainly protien food or a protien shake..any input advice would be great. 

You're doing great, just keep doing what you're doing. Ignore the averages the dietitian is telling you. You are unique to you.

Sounds like you are doing fine.  Everyone's plan is different so at this point, find a way of eating that works for you, protein first and you should be fine.  As time goes on, you will probably want to increase your protein to around 100, especially with your exercise.  Most of us haven't counted calories, but protein.  If you use an online tracker, you can see your calories too but protein totals are your main concern.
