Based on what you described eating in a day, I suspect you aren't eating/drinking enough and definitely not getting enough protein. I agree with Diane in that you should find some foods that you like and puree them. Tuna salad, chicken and gravy, chili, and some other things that have a bit more to them than cottage cheese. I suspect you are being a little too cautious, and I understand. Learning this new way of eating isn't "natural" for us. We have to relearn.
The important thing, like Diane mentioned, is making sure you are meeting your protein and fluid goals for the day. My protein shake intake hasn't changed since starting puree. The small amounts of puree don't generally have enough protein or calories to replace a shake. I still use drinks to ensure I get at least 60g of protein from that source. Generally, your protein goals after the liquid phase should be 0.3 x bodyweight. The pureed food I try doesn't really replace anything I was doing during the liquid phase. In my diet, the purees are replacing the soup I was eating for "meals" during the liquid phase. It is almost an equal caloric trade-off, and the protein is supplemental, so I have to keep up the protein drinks and fluids as I was before.
I really wish you had contact with your nutritionist. It's not very supportive of the weight loss clinic you used to not allow some sort of communication with your nutritionist before you see them in person. It seems like that would be very helpful for you. I know it has been helpful to me.
