8 week appt with nutritionist this week

I will have my 8 week post-op appt with the nutritionist who will finally give me the go-ahead for vegetables! I have a big organic garden full of veggies I can't eat and it's killing me! So this appt is very exciting. The food restrictions will be lifted and I can start eating more normal food. But..... I am scared. I have been doing great for the past month on 500 cal/day - protein shakes and protein foods. When I add some berries to my morning smoothie, some veggies and a salad with meals, and then try to gradually add more legumes, seeds, and nuts, the calories are going to go up. I have been losing 4 pounds/week for the past month, and I don't want to lose that momentum. I have also been adding more to my exercise regimen every week and will continue to do so. (Presently, I walk at least 10,000 steps, climb 10 flights of stairs, do 100 wall pushups, and alternate between Elliptical and weights, every other day.) I will add time to the Elliptical each week and more time/pounds to the weights each week. Anyway, I am hoping the extra exercise will counter act the extra calories, My plan is to increase the calories 100/day at a time for at least a week to find the amount I can eat and still keep losing. Does this sound reasonable? I have been doing so well, and I just don't want the additional food groups to cause a stall.
