    There are a lot of people who are overweight all over the world. What causes obesity? If you get the gene(基因), well, probably you are going to be a few more pounds heavier compared to the rest of your classmates or friends. ____ Obesity can not only make a person look heavy, and not in the usual sense of being handsome, but can also lead to serious health conditions and life-threatening diseases.

    ____ Indeed, junk food has been blamed for the prevalence(流行)of obesity. It is called junk food, because hamburger, pizza and the like contain high calories. If you eat a Big Mac (a super hamburger), an order of large fries, and a large Coke, you will need to walk non-stop for six hours to burn off the calories you have gained. And don't be fooled by soft drinks, which are high in sugar and are a major cause of obesity.

    ____ Popular sugary drinks, of course, include Coca Cola, Pepsi(百事) Cola, and many new brands that appear on the market every couple of days.

    ____ Just one 20-ounce (about 567g) bottle of soda can have 250 calories, which are equal to more than 16 teaspoons of added sugars. Even a lemon-flavored iced tea can have 210 calories.

    ____ Next time, when you are ready to eat that huge Mac and to drink that two-liter bottle of Pepsi, probably it's a good idea to give it a second thought.

A. Obesity is more common in women than men.

B. Most people don't realize how easy it is to gain weight from drink sugar-sweetened beverages(饮料)

C. When we talk about obesity, the first thought that comes to mind is: junk food.

D. The unburnt calories will put weight on you.

E. Keeping healthy is our own responsibility.

F. Because of their high content of sugar, soft drinks are also called sugary drinks.

G. However, the most common cause of obesity is eating too much, especially too much junk food.
