Eating junk food can have a significant impact on one's health. Though many people enjoy eating junk food and think it tastes great, the health consequences can be serious, and can range from everything to low energy levels to weight gain and illness. The term "junk food" encompasses a fairly broad category of food, but it typically refers to foods that are relatively high in caloric content, but low in nutritional value.
Junk food is often high in sugar, salt, white flour, and fat, particularly saturated fat. It is often heavily processed and prepackaged, making it easy to prepare and consume.

In addition, junk food can cause moodiness, and make it difficult to get enough sleep at night, so energy levels are never restored to normal.
