A crash diet is a general term for an extreme diet that is severely restrictive in its calorie intake. It’s meant to achieve rapid weight loss, and not meant to last for more than a few weeks at a time. An example of a crash diet is four glasses of skimmed milk, four bananas, one vitamin capsule, and large amounts of caffeine per day. Many celebrities go on crash diets when they want to lose weight quickly. Recently, Lindsey Lohan was quoted describing her crash diet: “It was just a crazy diet, nothing but cantaloupe, fruit juice and water, plus a two-hour workout, seven days a week.” Crash diets are typically unhealthy and are rarely, if ever, recommended by health professionals. Often, as soon as a dieter stops a crash diet, he ends up gaining back the weight he lost and then some.
