Avoid crash diets. They are bad for health and you will gain what you have lost once you take a break. Crash diets are not a solution to weight loss. It might seem as if you have lost few pounds but the moment you give up on the crash diet every thing will bounce back with a vengeance. Take a look at it in this way. Do you think that it is possible for a person to survive on a crash diet for the rest of his or her life? Certainly not! So at some time or the other, you will have to give up the crash diet and then you will see for yourself that a crash diet does more harm than good on the long run.
Crash diets may have a lot to promise, but very rarely do these promises ring true. Crash diets are things people go on in order to wear an old dress or suit for a particular occasion. That’s the only purpose that they serve as far as I can see.
