A serving size of nuts/seeds is one ounce. I am very careful to count them out and only sometimes eat two ounces if I know it is replacing a meal and it's going to be awhile before I eat again. I always have them on me for emergency situations or hunger on the go. Obviously a lot of people have a problem portioning nuts/seeds. The very worst thing you can do is eat them from the bag/container! Carbs from nuts/seeds add up fast if not kept to strict portion control.
