I think the amount you consume depends on how far out you are from surgery. I personally feel you must remove the triggers to get some kind of control. If you are truly hungry feed your body some type of protein- I have tried drinking skim milk and waiting to see if that helps. 3 meals is what my NUT told me to aim for- since grazing will lead to weight gain. As you can tell that hasn't been what I've done lately! On a good day a Protein shake made with milk for breakfast- lunch about 2oz chicken breast chopped up in lettuce tomato carrots, with regular salad dressing- dinner 3oz pork chop with green Beans and about 1/4c of mashed pot. If hungry in between some Greek yogurt! I think I feel hungry when I am truly just thirsty... I have read that if you have all of your protein in for the day and you still feel hungry, drinking something will help. Be prepared have high protein food in your house. So when you go for something it will satisfy you longer. The sugar craving are getting better for me with each day I avoid them!
