Trying to retrain my tummy

to learn that it's not going to get fed every time it growls, especially in the evening.  I'm getting a better feel for real hunger vs. some of the "sport eating" I used to do when passing through the kitchen, Costco or other places where food is easily accessible, i.e. pop cakes in the grocery.  Keeping a food log is making me conscious of just how many calories I used to eat casually, especially things like chunks of cheese, a couple spoonfuls of almond butter or a little dish of buttered pasta or quinoa at night.  I'm still going to have a snack at night but I'm trying to find better options, like a 130 calorie Greek yogurt instead of pasta or cheese.  If anyone has healthy snack ideas to share, I'd love to hear them.  Thanks.
