The Energy Diet

How can I lose weight when every time I go on a diet, I'm so exhausted that I can barely make it through the day? So goes the complaint of many men and women who are concerned about being overweight. What many people don't realize is that a healthful weight-loss plan can actually boost your energy. The key is to eat smart. And then combine this healthful diet with some physical activity. Here are six pointers to get you started.

1.____

Consume too few calories and you'll have less energy, and decrease the amount of calories burned. "That's because one of the ways the body protects itself from starvation is to slow down its metabolism," explains Dr. Donald Hensrud, a nutrition professor at the Mayo Clinic, in Rochester, Minn. So how many calories do you need to feel energized while also slimming down? A healthful weight-loss rate is roughly one-and-a-half pounds per week, and the calorie intake to achieve this depends on your age, weight, and activity level.

2.____

The key to keeping your energy level up when you diet is to eat balanced meals that supply all the nutrients you need. "Vitamins and minerals act like spark plugs," explains Kristine Clark, director of sports nutrition at Pennsylvania State University. "They help release the energy in nutrient-rich food." Try to follow USDA guidelines. They call for 6 to 11 servings per day from the bread, cereal, rice, and pasta group; three to five servings of vegetables; two to four of fruits; two or three of milk or cheese; two or three of meat, fish, or eggs. Avoid fried and creamy dishes, and keep consumption of sweets and desserts to a minimum.

3____

When you go for five to six hours without food, the amount of fuel in your system starts to run low, and you begin to feel tired. Therefore, says Kristine Clark, it's important to eat at regular intervals to keep your energy up. If you exercise, it's important to make sure you have "fuel in the tank" before you head for the gym. Avoid eating a large number of calories at one time, since it's harder to control your total calorie intake, making weight gain more likely.

4____

About 10% of women of childbearing age in the United States are iron deficient. Iron is essential for energy and endurance because it is a vital component of red blood cells, which carry oxygen to working muscles. "Fatigue and listlessness can be directly associated with too little iron," says Frances Berg, a licensed nutritionist in Hettinger, N.D. The best sources of iron are meat, poultry, and some fish. Other sources: fortified cereals, dried beans, dried fruits, and peas.

5____

"I don't have the energy to exercise!" say many dieters. Indeed, a 1998 survey, developed in part by the Center for Sports Medicine at Penn State, found that over 70% of respondents cited "too tired" or "lack of energy" as key reasons to skip exercising. Yet exercise is exactly what these people need. And, lastly, don't try to do too much too soon. Consider breaking your exercise into small units. Instead of trying to do 30 minutes in one chunk, accumulate exercise in short bouts （一場，一回）every day by mowing the lawn, walking to work, or climbing stairs instead of taking an elevator. It won't be long before you reap （收獲）the rewards. Imagine carrying a 15-pound sack of groceries around all day. Then think about how much more energy you'd have if you put that sack down.

We already know the fastest, least expensive way to slow climate change: Use less energy. With a little effort, and not much money, most of us could reduce our energy diets by 25 percent or more—doing the Earth a favor while also helping our wallets. 

Not long ago, my wife, PJ, and I tried a new diet—not to lose a little weight but to answer an annoying question about climate change. Scientists have reported recently that the world is bending up even faster than predicted only a few years ago, and that the consequences could be severe if we don’t keep reducing emissions（排放）of carbon dioxide（CO₂）and other greenhouse gases that are trapping heat in our atmosphere.  21世紀(jì)We decided to try an experiment. For one month we recorded our personal emissions of CO₂^. . We wanted to see how much we could cut back, so we went on a strict diet. The average US household（家庭）produces about 150 pounds of CO₂ a day by doing common-place things like turning on air-conditioning or driving cars. That’s more than twice the European average and almost five times the global average, mostly because Americans drive more and have bigger houses. But how much should we try to reduce? For an answer, I checked with Tim Flannery, author of The Weather Makers: How Man Is Changing the Climate and What It Means for Life on Earth. In his book, he had challenged readers to make deep cuts in personal emissions to keep the world from reaching extremely important tipping points, such as the melting（融化）of the ice sheets in Greenland or West Antarctica. “To stay below that point, we need to reduce CO₂ emissions by 80 percent,” he said. 

Good advice, I thought. I’d opened our bedroom windows to let in the wind. We’d gotten so used to keeping our air-conditioning going around the clock. I’d almost forgotten the windows even opened. We should not let this happen again. It’s time for us to change our habits if necessary.

B. it seems possible for every household to cut emissions of CO₂

C. the average US household produces about 3,000 pounds of CO₂ a month.

D. the average European household produces about 1,000 pounds of CO₂ a month.

Which of the following would be the best title for this passage?

 A. Saving Energy Starts at Home         B. Changing Our Habits Begins at work

 C. Changing Climate Sounds Reasonable  D. Reducing Emissions of CO₂ Proves Difficult

Do you know that a Mom deserves a special gift this year for Mother’s Day? Sure, flowers can always brighten Mother’s day and a dinner out is always appreciated. However, doesn’t she deserve something more personal or something that lasts longer than an evening?

I’m talking about the gift of fitness. Improved fitness is a gift that is invaluable to everyone. When you give a woman the gift of fitness, you are helping her open a door to better health. I can’t think of a more thoughtful gift that shows the recipient(接受者) how much you care about their well-being. By giving the gift of fitness you are providing them with unlimited health benefits. And, its a gift that you can truly feel proud to give.

Of course, we all know that exercising can help people stay slim and fit. But, do you also know about all the other great benefits of exercising? Daily physical activity reduces stress and can help you sleep better. Fitness has been linked to reducing the risk of some diseases and to warding off depression. Researchers also believe that strength training can help prevent osteoporosis(骨質(zhì)疏松). Not to mention that exercising also improves self-esteem, increases energy and helps you be able to do continuous work for longer.

All Moms would find these fitness benefits extremely invaluable. If they are like most of us, they have probably even mentioned how they would like to drop a few pounds or just get in better shape. In fact, experts say that about 62% of Americans are currently on a diet. By giving the gift of fitness you are helping provide your mom with extra motivation. She may be more motivated to actually get fit because she doesn’t want to feel guilty about ignoring such a thoughtful gift .

1.The first paragraph is most likely to tell us that___________.

2.You would like to send the gift of fitness to your mother because__________.

3.You want to keep healthy you should__________.

4.According to this passage the gift of fitness will____________.
