【雅思聽(tīng)力】肥胖(3/4)

Most of those suffering from excess body weight would go a long way toward solving their problem if they regularly did moderately vigorous exercise, for instance, 30 minutes per day of swimming,cycling or brisk walking. So what exactly is the problem if a person weighs more than they should? Firstly, this can put too much strain on the joints such as knees and ankles. The health consequences of having excess body fat depend on what part of the body the fat is found on. Fat on the abdominal area is often associated with diabetes and heart disease, whereas there's no apparent connection between those conditions and having fat on the thighs and hips. Being overweight can also give rise to problems apart from those of physical health. In childhood, even more so than later in life, people need to feel that they belong. Children who are rejected and ostracized by their classmates because they're overweight and not fit may develop low self-esteem. Although scientists are still unsure why some people gain weight more easily than others, it's clear that the right food, together with regular exercise, is the only way to lose weight and not put it back on.
