There is a weight loss diet that focuses on just about every type of food out there, and popcorn is no exception. Popcorn is a handy food that is inexpensive, easy to make and high in fiber. Eating popcorn regularly, as long as there isn't butter or excessive salt added, can be part of a healthy, low-calorie diet for weight loss.
Buy a hot air popper and popcorn kernels, and use those items to make popcorn instead of using microwave popcorn in your diet. Pop the popcorn without using oil to keep it low-calorie.
