Avoid crash dieting: It can be extremely dangerous for your vital organs like heart, kidneys, liver, and brain.

In order to perform their daily functions, your vital organs rely on energy from your carbohydrate intake. During strict crash diets, carbohydrate and calorie intake is so low, that your organs cannot get enough energy from these sources. As a result, your organs begin to burn the lean tissues of your heart, liver, kidneys, brain and other organs. In the long term, this can result in serious health problems.
