Snacks for me include:
Nuts (especially cashews and almonds)
Cheese and crackers
Fruit (watermelon, apples, pears)
Vegetables and dip
Popcorn
Ice Cream
Salt Water Taffy (for those moments of OMG I need something sweet but don't want to eat much)
Chips/pretzels
I also often make myself a treat every week. Last week was apple bread, this week will be a vanilla cake. I'm an "everything in moderation" sort of girl which has helped me stay under/at my calorie goal for the past couple of weeks.
