There is a(n)  27  – a surprising, opposite result – to all this dieting. While many people are becoming thin, other people are becoming overweight. More people are overweight than in the past! In many countries, there is a  28  problem with obesity. There are two main reasons. First, these days, many people often go to fast-food restaurants. At these restaurants, many of the foods (such as fried potatoes and deep-fried meat) are  29  in fat, so are some of the dairy products. Second, dieting doesn’t often work. Sometimes people  30  weight fast, but they usually gain it back again. Almost 95 percent of all people gain back weight after  31  . One problem with obesity is easy to see: overweight people have more sicknesses, such as heart disease and diabetes. (excerpted from Interactions Access by McGraw-Hill, 2007)
