If you asked me:"Shall we diet in order to keep fit?" The answer is definitely no.I think going on a diet is not a good way to keep fit.As we all need nutrition everyday.We should have an adequate,balanced diet to support ourselves.Going on a diet is harmful to our health.For the sake of ourselves,we'd better not do that.There are many other ways to keep fit despite of dieting,such as doing exercises.Ecercising is a more effective method to loose weight and beautify our figures.We can do this instead of going on diet.After all,health is the most important thing.
