Crash dieting is when you cut your calorie intake dramatically to lose weight fast. So why is it a bad idea? STACK talked to sports dietician Leslie Bonci to find out why you shouldn't go on a crash diet.
Another unpleasant characteristic of crash diets is that they are boring. Since your calorie intake drops, you have fewer food options to choose from. You tend to eat the same food every day, which can make you sick of it very quickly.
Finally, a crash diet affects your mental as well as your physical performance. When you don't eat a sufficient number of calories, you become more fatigued, which can lead you to become unable to focus in the classroom or on the field.
