Crash diet and fad diet are general terms. They describe diet plans which involve making extreme, rapid changes to food consumption, but are also as disparaging terms for common eating habits which are considered unhealthy. Both types of diet are often considered to pose health risks. Many of the diets listed here are weight-loss diets which would also fit into other sections of this list. Where this is the case, it will be noted in that diet's entry.
