Now many people are thinking about going on an extreme diet. Some of them think that this diet is normal and you can lose weight quickly. Other people think that it isn’t good idea.

Of course, these diets have some advantages. Firstly, if you go on an extreme diet, you will see the result quickly and it will motivate you to continue the diet. Secondary, it will be like self-control to you, because you have to focus on the diet if you want result.

On the other hand- extreme diets have some disadvantages. They are difficult to follow and you may give up quickly and regain the weight. Also, diets have many restrictions. This minds, you may not get the nutrient which you need to stay health.

So these diets have both : advantages and disadvantages. In my opinion,people shouldn’t go on a diet without doctor’s advice.
