100 calorie Sierra Mist
Pretty much any of those cute, short little 8-ounce cans of soda are 100 calories (for the non-diet variety.) But they’re usually as costly as their 12-ounce big brothers. They are convenient, though, and if you find a good sale they’re a great way to measure your soda calorie count. I recently picked up a six-pack of 100 calorie Sierra Mist when my son had a tummy ache (the only time he’s allowed soda.)
