    A crash diet is a diet which is extreme in its deprivations - typically severely restricting calorie intake. Meant to achieve rapid weight loss, a crash diet differs from outright starvation only slightly. Crash diets are typically unhealthy and are rarely - if ever - recommended by doctors or dietitians. Crash diets can lead to malnutrition, and are not a recommended means of weight loss.

    After a person discontinues a crash diet, the "yo-yo effect" is often seen. This causes a person to eat far more than normal, causing them to regain both the weight that was lost due to the diet as well as additional weight. This is caused by an evolutionary trait of the human race that historically only took effect in times of famine: after a famine ended, people's bodies naturally craved to regain both the weight that was lost, plus additional weight as well, in order to protect themselves in case of another famine.

    An example crash diet consists of a daily intake of 4 glasses of skim milk, 4 bananas, and 1 vitamin capsule; a boiled egg may be substituted for a banana. Also, large amounts of caffeine.[1]

    You mess up your metabolism. You risk serious illness. You mess up your body's balance of minerals. You could do some major damage. Plus you don't really learn anything about how to keep the weight off, so once you're off the crash diet, you're going to gain back everything you lost, with interest.

    You're a lot better off taking the slow and sensible approach. It takes longer, but you're more apt to keep it off because you've learned the lessons about how to keep it off.

    do NOT crash diet. the reason why is because if you take in a very little amount of calories, sure you will loose weight for the time being on the diet, but when you are finally happy with your body and want to go back to a regular diet, your body will hang on to the calories even more so than in the first place, therefore resulting in weight gain. so in other words, while you are on the diet, you will be skinny, but when you go off the dies, you will be fatter than you were int he first place.

    You are at risk of not getting enough vitamins and minerals to stay healthy if you severely restrict your food intake.

    After using up your glycogen, you will start losing weight from your body's tissues, as your body frees up energy to keep you going. Crash diets do this too quickly to be healthy.

    Crash dieting tends to make dieters tired, irritable, and lethargic, and brings on food cravings.

    In short, you lose weight quickly, but your metabolism slows down so when you get off the 'diet' you re-gain VERY easily and since your body is trying to hoard calories (because you deprived it on the diet) chances are you may gain more than you had to lose in the first place.

    BAD weight loss method.

    I lost weight fast a few years ago and it caused my mind to go into some sort of 'shock', which then caused me to eat even more. I then started to eat a lot of food as a sort of 'catch up'.
