Crash Diets or the Yoyo Diets
In trying to lose weight fast, a lot of people sort to “crash diets” or sometimes called as the “yo-yo diets.” This kind of diet plan forces you to drastically cut down on your calorie intake.

Its effect doesn’t last long since you cannot stand its restrictive approach.

Since your body adjusts to its metabolism, it now burns fewer calories to supply the energy need of your bodily actions. If this continues, you are likely to get fat easily when you eat a little more after your diet. Your body’s metabolism stays slow for few months or even years even after your crash diet since you conditioned it to burn fewer calories.
