There have always been a lot of commonly believed but false ideas about being fat and doing exercise. Some people believe that they can’t help putting on weight as they get older, while others hold that if they stop exercising, their muscles will turn into fat. Here are some more myths:
I’ll never lose weight --- I come from a fat family
Wrong! While we can’t change the body type we are born with, we can’t blame our genes for making us fat. There’s plenty of evidence that fatness runs in families, and the main reason is that they share the same habits of eating too much and exercise too little.
I am fat because I burn calories slowly
Wrong! Fatness is not caused by a slow metabolism（新陈代谢）. If fact, although fat people consume more energy that slim people, they also fail to realize how much they eat! Keeping a diary can help you work out your daily food intake more accurately.
Exercise is boring
Wrong! Anything will become boring if you do it repetitively. The key is to develop a balanced and varied program that’s fun as well as progressive. If you enjoy a Sunday walk, take a different route. If you do Yoga, try a tai chi class. If you like swimming, set yourself a distance or time challenge.
No pain, no gain
Wrong! Exercise is not meant to hurt. Indeed, pain is your body telling you something’s wrong, and continuing to exercise could lead to serious injury. You may experience mild discomfort as you begin to exercise regularly, but this your body adapting to the positive changes in your lifestyle and the aches should disappear relatively quickly. If you don’t, rest and seek medical advice.

? ?Obesity
refers to the medical condition characterized by storage of excess body fat. The
human body naturally stores fat tissue under the skin and around organs and
joints. Fat is critical for good health because it is a source of energy when
the body lacks the energy necessary to sustain life processes, and it provides
insulation and protection for internal organs. But too much fat in the body is
associated with a variety of health problems.
? ?Most physicians
use the body mass index (BMI) to determine desirable weights. BMI is calculated
as weight divided by height and people with a BMI of 27 or above are considered
obese.
? ?Weight-height tables, such as those published by the
Metropolitan Life Insurance Company, are also used as general measures of
desirable weight ranges3. These tables assign a range of weights for a
particular height. For example, a man of 1.8 m has a desirable range of 66 to 83
kg, with an average of 75 kg. A woman who is 1.6 m has a desirable range between
53 and 70 kg, with an average of 62 kg.
? ?The BMI and
weight-height tables only provide rough estimates of desirable weights and
scientists recognize that many other factors besides height affect weight.
Weight alone may not be an indicator of fat, as in the case of a body-builder
who may have a high BMI because of a high percentage of muscle tissue, which
weighs more than fat. Likewise, a person with a sedentary lifestyle may be
within a desirable weight range but have excess fat tissue.
?
?Obesity increases the risk of developing disease. According to some
estimates, almost 70 percent of heart disease cases are linked to excess body
fat, and obese people are more than twice as likely to develop high blood
pressure. Obese women are at nearly twice the risk for developing breast cancer,
and all obese people have an estimated 42 percent higher chance of developing
colon cancer. The risk of medical complications, particularly heart disease,
increases when body fat is distributed around the waist, especially in the
abdomen. This type of upper body fat distribution is more common in men than in
women.
? ?The social and psychological problems experienced by
obese people are also formidable. Stereotypes about "fat" people are often
translated into discriminatory practices in education, employment, and social
relationships. The consequences of being obese in a world where people had
better be "thin" are especially severe for women, whose appearances are often
judged against an ideal of exaggerated slimness.
