What do you think about all the different diets that people go on ?   I don't think dieting is good for you . It's much better to eat a balanced diet and to never get overweight to begin with !   But what do you think about people who are obese ? What should they do to lose weight ?   They need to eat healthy foods , but they also have to increase the amount of physical exercise every day . They don't have to cut out fattening foods altogether , though .   So you think it's OK for people who are dieting to eat chocolate , don't you ?   Sure , they can eat some chocolate . As long as they are exercising and eating mostly healthy foods , there's nothing wrong with having a small dessert .   How about drinking soda ?   Many people gain weight by drinking far too much soda . Soda should be treated seriously ; there's simply no nutritional value in it whatsoever .   And have you ever tried taking vitamins ?   I used to take vitamins every day , but I don't take them anymore . Vitamins are good as a supplement , but they don't do much good if you don't have a well-balanced diet to start .   How do you know so much about food and dieting ?
