Snack on popcorn
One cup of plain popcorn with just a little salt only contains around 35 calories. However, because you spend so much time munching on a handful, and because it’s a whole grain, a little bit of popcorn can fill you up. Next time you want to reach for, say, pretzels (228 calories in just 10 small ones) try popcorn instead. If you’re a big snacker, you could save yourself hundreds of calories a day by switching to popcorn.
