Nowadays , many people think that a special diet help them to keep fit. on the contrary , other people consider that diet have disadvantages. i can understand this point of view.  on the one hand , i am for following a diet. people follow a diet , because they think that is the best way to lose weight. and i feel the same. people dreams of a beautiful body and they aim at it. in my opinion , diets are a good opportunity to lose excess weight. there is the concept of "proper nutrition" including a balanced amount of proteins , fats and carbohydrates. in my view , the proper nutrition contribute to cleanse the organism from useful substances.  on the other hand , doctors are against following a diet , because if people ignore the rules of diet , it will leads to awful consequences. therefore , the best way to lose weight is doing sport. from my point of view , if you lose excess weight you will need to keep fit , because nobody likes flabby body. moreover , dieting lowers your metabolic rate , so when you return to your normal food intake , you will put on weight even faster than before.  to sum up , i think that following a diet is necessary only on the doctor's recommendations. as for me , sport is the best way to keep fit. sport warn people against dying.
