Yes its true, crash diet may be the shortest and effective way of losing weight but the after effects of the crash diet I suffer later is worst.

Whenever I go through a crash diet I need to under go extreme nutritional deprivations, typically severely restricting calorie intake. This indeed leads to rapid weight loss but the final result is that i regain most of my weight within few weeks.

So all my starvation and resisting myself from yummy food becomes worthless after this crash diet.
