Nuts
Measure out and transfer 1-ounce portions into resealable bags. While nuts are a very healthy food and have even been shown to assist in weight loss, one large handful could hold more calories than you need.
Hard cheese
Runnersworld.com offers this tip for cheese: Whenever you have a block of cheese, read how many servings come in a package, and then score the cheese appropriately so you know what a single portion should look like.
Butter and cream cheese
Score as you did for the cheese into teaspoon-size portions for butter and 1-ounce portions for cream cheese.
Ice cream
You know when you get home and the ice cream is the perfect consistency? Take that time to scoop out the ice cream onto a cold cookie sheet. Place the sheet in the freezer until the ice cream is solid then transfer to a large freezer bag. The typical ice cream scoop is a half cup which is also the amount in a serving. When you want a serving, pop it in a cup and enjoy without the bent spoons and accidental extra ingestion.
