Jasgot and Tandern,
I like edieparks have had incredible success and had the same fears as yourself before I was banded. Asking the questions you are asking is the first step you should make.
The answer about caloric intake is to measure yourself on the scale and count your calories. The surgery really helps you with portion control. Eat fresh foods and never step foot into a fastfood place again. I haven't because after eating healthy- the food is absolutely disgusting. If you let yourself- you can walk down any chips/baked goods/ cracker aisle at the supermarket without stopping and feel so proud for it. In addition, you have to look at the surgery as a JOURNEY!! You will try a variety of foods and some will work while others will not. It's different for everyone. I personally try to stay away from Soups and soft foods simply because they don't fill me as if I was eating a small piece of fish, chicken or steak. I never eat sandwiches because bread is something I cannot eat anymore. I have for lunch about a few ounces of shaved turkey (shaved really helps get it down), a slice of diet cheese or salad or cooked veges (whatever I have room for ). My Breakfast consists of a Light n' fit yogurt and a Protein bar. My dinner is usually meat of some sort ( a few ounces) and salad or veges. I drink Soy milk in my coffee and sometimes I will drink Isopure if I feel I am too little on my protein.
I mix it up and I excercise because I LOVE to try out things I could never do before. It blows my mind to think I will do an hour of Step aerobics after an hour of Pilates.....Anyway, this like life itself is a journey full of twists and turns. However, never give up, be honest and ENJOY THE RIDE!!! Understand that food is really not that exciting of a thing when you can express yourself and MOVE like you have never done so before. There are so many opportunities before you. Don't waste one more moment of your life obsessing over food. Be "Bigger" than that- Good Luck!
