Lots of people are unhappy with their present weight, but most aren't sure how to change it. You may want to look like the models or actors in magazines and on TV, but those goals might not be healthy or realistic (现实的) for you. Being healthy is really about being at a weight that is right for you. The best way to find out if you are at a healthy weight or if you need to lose or gain weight is to talk to a doctor or dietitian（营养学家）. If it turns out that you can benefit from weight loss, then you can follow a few of the simple suggestions listed below to get started.
_______________________. Ask your mom or dad to lend help and support and to make lifestyle changes that will benefit the whole family, if possible. Those who have the support of their families tend to have better results with their weight-management programs.
Watch your drinks. It’s amazing how many extra calories can be in the sodas, juices and other drinks that you take in every day. Simply cutting out a can of soda or one sports drink can save you 150 calories or more each day. Slake yourself with water or other sugar-free drinks when you’re thirsty and stay away from sugary juices and sodas.
Stop eating when you’re full. Lots of people eat when they’re full. Try to pay attention as you eat and stop when you are full.
Avoid diet pills. They can be dangerous to your health; besides, there’s no evidence that they help keep weight off over the long term.

Most people regard zoos as safe places for animals, where struggles such as difficulty finding food and avoiding predators（捕食性动物） don't exist. Without such problems, animals in zoos should live to a ripe old age. But that may not be true for the largest land animals on Earth. Scientists have known that elephants in zoos often develop diseases, joint problems and behavior changes. Sometimes, they even become unable to have babies.

To learn more about how captivity(监禁) affects elephants, a team of international scientists led by Mason, a biologist, compared the life spans of female elephants born in zoos with female elephants living outdoors in the wild. Zoos keep detailed records of all the animals in their care, documenting factors such as birth dates, illnesses, weight and death. These records made it possible for the researchers to analyze 40 years of data on 800 elephants in zoos.

The team found that female elephants born in zoos lived an average of 16.9 years. Their wild counterparts（同类事物） who died of natural causes lived an average of 56 years——more than three times as long.

Scientists don't yet know for sure why wild elephants seem to live so much better than their zoo-raised counterparts. Mason thinks stress and obesity(肥胖) may be to blame. Zoo elephants don't get the same kind of exercise as they do in the wild, and most are very fat. Elephant social lives are also much different in zoos than in the wild, where they live in large groups.

Another finding from the study showed that elephants born in zoos were more likely to die earlier than elephants captured in the wild and brought to zoos. Mason suggests stress in the mothers in zoos might cause them to have babies that are less likely to survive.

The study raises some questions about acquiring more elephants to keep in zoos. While some threatened and endangered species living in zoos reproduce successfully and keep healthy populations, that doesn't appear to be the case with elephants.

Living a healthy lifestyle contains making choices about the foods we eat as well as exercise and other daily activities．The term "healthy lifestyle" can be defined as "to improve and protect one's health and well-being"．

     For this purpose, a healthy lifestyle can involve good eating habits, regular physical activity and anti-alcoholism．

     First of all, good eating habits are the main way of living a healthy lifestyle．For instance, rushed morning routines, trying to lose weight, and lack of appetite （食欲）early in the morning are all reasons why people skip breakfast．However, most experts think that breakfast is the most important meal of the day．Another example is fast food; a hamburger from McDonald's with special sauce and cheese is not exactly considered as a healthy meal．Our society today is busy and on the go at all times．It is much easier to stop and get fast food．As a result, humans become fatter．However, eating low-fat meals that include 5 to 9 servings of fruits and vegetables every day is an ideal healthy life plan．Therefore, good eating habits are the main way of living a healthy lifestyle．

     Secondly, another way of living a healthy lifestyle is physical activity．Exercise is indeed part of life because it keeps the body and mind in good shape．Exercise reduces stress and contributes to （有助于）a good sleep．It can keep a person looking and feeling younger throughout his entire life, and it also helps build one's energy and strength．Many people do not think too much about their health until they get sick．So, physical activity is another way of living a healthy lifestyle．

     Finally, another way is anti-alcoholism．Addiction （上瘾）to alcohol may cause serious social and public problems．It is accepted that driving after drinking is dangerous．Alcohol is a main factor of traffic deaths．Alcoholism can also lead to diseases, such as heart attack or liver trouble．Thus, anti-alcoholism is another way for a healthy lifestyle．

     In conclusion, a healthy lifestyle can be maintained in three ways: the first way is good eating habits, the second way is regular physical activity and the final way is anti-alcoholism．
