Dear David,

    Sorry to learn that you've put on weight. Eat too much food in McDonald's and KFC must be the reason. You have to realize that food is not always as healthy as was said in the advertisements. If you know much about them, we will find fried chicken and French fries are rich in fat, sugar and salt. They can make you to gain weight and become sick.

    That you ought to have every day are noodles, rice, fruit and vegetables rather than the junk food. Energy-giving food, body-building food and protective food makes up a balanced diet. In word, you must have an idea of how a healthy diet should be and stick to it.

    I hope my advices can help you improve your health.

Yours,

Li Ming
