6. Popcorn

Who would have imagined that a treat that’s so often enjoyed at the movies is one that can help you lose weight? Although it might not be quite as appealing as a bag of potato chips, you can eat either three cups of air-popped popcorn or just a quarter cup of potato chips and pay the same price: 90 calories. Popcorn is light and fluffy and it does not take all that much to fill a good-sized bowl, which tricks your brain into thinking that you are eating more than you actually are. Popcorn also takes up a lot of room in your stomach and helps you feel full without a bunch of fat-producing calories.
