Crash Diet

-

A crash diet is a method to lose weight really fast in a short period of time by reducing the daily calorie intake as low as 700 calories a day.
It can shed some weight within days or few weeks.

IS CRASH DIET EFFECTIVE ?

If it is for a certain target date, for eg there is upcoming event or wedding party, it is the most effective method. 
However by depriving our body of so much calories and valuable nutrients puts a lot of stress in our body which may bring disadvantage and less effective method of losing weight.

Another name for crash diet is YO-YO effect.
Since we restrict too much calories, our body will go into survival mode and reduce the calories it burns during normal daily activity. When we start eating normal again, it's very easy to add the kg back on since our body is burning less calories.

There are MANY TYPES OF CRASH DIETS, I pick few ones

1. Juice Fast Crash Diet
Consume nothing but fruits and vegetable juice for at least 60 days and lose tons of weight and seem to get a lot healthier because we detox our body and feel energised. 
But if we do it for long period of time, our body may experience nutrients deficiency and has high risk of rebound weight gain.

2. Cabbage Soup Diet
On this diet, we are allowed to eat all cabbage soup we want and a few select other food. Cabbage is high in fiber which help to clean up our body system
