Not all diets are considered healthy. Some people follow unhealthy diets through habit, rather than through a conscious choice to eat unhealthily. Terms applied to such eating habits include junk food diet and Western diet. Many diets are considered by clinicians to pose significant health risks and minimal long-term benefit. This is particularly true of crash or fad diets – short-term weight-loss plans that involve drastic changes to a person's normal eating habits.
