The essay topic is : dieting can change a person's life for better or ruin one's health completely . What is your opinion ?

Nowadays, dieting became very essential for people everywhere , and this refers for many reasons such as being fit,keeping body healthy,and for beauty aims.And by years ,reports show that by the 2050 , half of United State citizens are at risk of getting fat, for this reason ,many associations impelled to encourage people doing sport and dieting .Meanwhile,many people were against dieting and they encourage doing sport only , they claim that dieting has a detrimental effect on people's health .

Admittedly , dieting is very important to keep our body free of fatal diseases like heat attack,strokes,sugar diabetes ,and many other.
People who had a disease or over weight obviously, they will do a diet to get rid of his problem. Unfortunately ,a lot of them instead of getting healthy they had additional diseases like blood ,and even psychological disease for instance .

Actually, I believe that making a diet is always good , just if doing it in right way ,and under the supervision of diet specialist because he will advice an integrated nutrition program that is specifically suitable for each person separately.

In conclusion , dieting has a pros and cons . But we can get the advantages if we make it in right way .In addition ,every person should do sport and eat natural products and be away of fat food to have a healthy life .
