　　Passage Three

　　Diet, diet, diet! It gets to be a constant battle for many of us to stay fit and healthy. But diets dont always allow us to learn new eating habits, improve our self-image, or make lifestyle changes. Developing good eating habits and proper exercise is a permanent issue. And its the main topic of this workshop.

　　In order to keep a healthy diet and minimize the risk of disease, its essential to eat a diet that consists of low fat foods and to maximize energy with carbohydrates. Beef, nuts, oils, and most dairy products are rich in fat, so you should eat less of those; while pastry, rice, potatoes, and bread contain almost no fat and are a high energy source of complex carbohydrates. You know that many food manufactures use sugar to make low fat or fat free foods taste good, but dont worry too much about that. You dont necessarily get fat by eating sugar, since sugar is an indirect fat.

　　When you exercise, carbohydrates are the first calories to burn, if you want to burn off fat, its good to do some sort of aerobic exercise such as biking, swimming, running, or fast walking. But you have to keep doing this exercise for at least twenty minutes because it takes about that long before we start to burn fat. And then the effect of burning fat decreases after forty-five minutes of exercise. So if you do some sort of aerobic exercise for three to four days a week for about thirty to forty minutes, youll have an affective schedule for reducing weight.
