Burn Calories in Your Sleep?
The weight-loss world is full of assertions(斷言), rarely proved, that some pill can help you “burn calories while you sleep.” But a recent Dutch study reports that it can be done – simply by eating more lean protein(無脂肪蛋白質(zhì)).
Researchers report for the first time that consuming nearly a third of daily calories as lean protein – for example, lean meats without the skin – speeds up a person’s metabolism(新陳代謝) during sleep and that higher protein intake increases the burning of calories and fat during the day. Plus, when the study’s participants, who were all women of healthy weight, ate more protein, they felt fuller, more satisfied and less hungry than when they consumed a diet with the amount of protein, about 10 percent of calories.
The findings suggest that adding lean protein to your daily food “enables you to reach the same level of satiety(過飽)that you are used to with about 80 percent of your normal energy intake,” notes Margriet Westerterp-Plantenga. “That means you can eat about 20 percent less and still have the same satiety.”
What gives protein its caloric edge? It’s more difficult for the body to metabolize protein than either fat or carbohydrates(糖類). The body also doesn’t store protein as efficiently as it does carbohydrates or fat. So protein is more likely to be burned and that in turn requires more oxygen and helps you feel satisfied in the hours after eating.
But the latest findings don’t mean it’s time to dust off those high-protein diet books. The current study limited fat to about 30 percent of daily calories, and included 40 percent of calories as healthy carbohydrates, including fruit and vegetables. For example, lunch included bread, soy milk, fruit yogurt, tuna in water, tomatoes, cucumbers, feta cheese and salad dressing.

Breakfast is not only the most important meal of the day, it is also the most neglected(忽視).Common reasons for not eating breakfast include lack of time, not feeling hungry, traditional dislike for breakfast, and dieting.
Breakfast simply means “Breakfast the fast”.Your body spends at least 6 to 12 hours each night in a fasting state.In the morning your body needs energy for the day’s work ahead.
A good breakfast should provide up to 1/3 of your total calorie needs for the day.On average, we eat 400 less calories for breakfast than for dinner.If breakfast doesn’t interest you, try eating a lighter dinner earlier in the evening or save half your dinner for breakfast ________.
So, you say you’re on a diet.Some people fear eating breakfast will make them hungrier during the day and they will eat more.It is true that eating breakfast is likely to make you feel hungry throughout the day.That’s because your body is working correctly.Although you may feel as if you eating more all day long, in reality you are probably not.
Not eating breakfast can also cause you to overeat, since a fall in blood sugar often makes you feel very hungry later.To make matters worse, since your body is in a slowed state it will not be able to burn those extra calories very efficiently(有效地).If you feed your body healthy snacks(小吃)and meals throughout and day, you are less likely to become hungry and stuff(填飽)yourself as soon as you begin to eat.
Since breakfast is the first important meal of the day, choosing the right fuel is important.The best breakfast foods are fruits, juice, lean(精瘦的)meat, and grain products such as bread, rice, noodles and so on.

Keeping a busy social life among lots of friends may keep people thinner than spending hours doing some exercises, according to scientists. They say that socialising and meeting with friends help increase levels of brown fat in the body which burns calories(卡路里)to produce heat.
Living in an exciting social environment was found to reduce fat in mice's belly by half over four weeks, even if they ate more. US researchers say that social excitement aids weight loss by turning white fat into brown. White fat stores calories and makes us fatter, while brown burns energy to produce heat. Turning white fat into brown is extremely difficult,normally
requiring long- term stay in cold conditions or exciting part of the body's nervous system.
However, scientists from Ohio State University now think that having a busy social life is an even more effective way of changing white fat into brown. The team came up with their theory by studying the effects of various living environments on mice. Those, who lived alongside a greater number of mice, had more space and toys to excite themselves and then lost far more weight over the course of the study than their “couch potato" fellows.
Study author, Dr Matthew During, whose team's findings appear in the journal Cell Metabolism, said, "I'm still amazed at the degree of fat loss that occurs." Explaining how new technology had threatened face-to-face socialising, he added, "It's not just a sedentary(久坐 的)lifestyle and high calorie foods, but an increasing lack of social activities." Co-author Dr Lei Cao said,"Loneliness is a potential factor for cancer and death; it's equal to cigarette smoking to a certain extent. Social activities are very vital.,,
【小題1】What information can we get from the first two paragraphs?
A.Brown fat stores calories and makes us fatter. |
B.It doesn't take long to turn white fat into brown. |
C.Social excitement helps gain more weight. |
D.Brown fat can burn energy to produce heat. |

B.The mice lacking social life lose more weight. |
C.The research findings haven't been published so far. |
D.Dr Matthew During wasn't convinced of the result. |
A.the fat in mice's belly was reduced because of the relaxing environment |
B.a(chǎn) sedentary lifestyle and high calories foods influence people's social life |
C.surfing the Internet may influence people's face-to-face communication |
D.cancer and death are mainly caused for lack of social life |
A.Brown fat is beneficial to people's health. |
B.Socialising is unnecessarily important in people's daily life. |
C.White fat can be changed into brown fat. |
D.Socialising contributes to people's losing weight. |

I know what you’re thinking: pizza? For breakfast? But the truth is that you can have last night’s leftovers in the morning if you want to.
I know lots of women who don’t have breakfast, and they have many different excuses for doing it. Some say they don’t have time, others think they’re “saving” calories(卡路里), still others just don’t like breakfast food.
But eating in the morning is very important when you’re trying to lose weight. Eating just about anything from 300 to 400 calories would be better than nothing at all.
Breakfast is one meal I never miss, and the same goes for most weight loss success stories. Research shows that eating breakfast keeps you from overeating later in the day. Researchers found that those who don’t have breakfast have a bigger chance of gaining weight than those who regularly have a morning meal.
So eat something in the morning, anything. I know plenty of friends who end up having no breakfast altogether, and have just coffee or orange juice. I say, try heating up last night’s leftovers-it may sound crazy, but if it works for you, do it! I find if I tell myself, “You can always eat it tomorrow,”I put away the leftovers instead of eating more that night. Try it…you may save yourself some pre-bedtime calories. And watch your body gain the fat-burning effects.
【小題1】The word “l(fā)eftovers” in Paragraph 1 probably means __________.
A.pizza topped with fruit | B.things left undone |
C.food remaining after a meal | D.meals made of vegetables |
A.be careful about what you eat | B.eat something for breakfast |
C.heat up food before eating it | D.eat calorie-controlled food |

A.who go to work early | B.who go to bed late |
C.who eat before sleep | D.who want to lose weight |
A.Better eat up all the food at dinner in the night. |

It takes more than just practice to become an Olympian. Gold medal performances require some serious nutrition. Have you ever wondered what these successful athletes eat to stay in peak shape?
Keri Glassman, a registered dietitian and founder of Nutritious Life Meals, appeared on “Good Morning America” today to give you a glimpse into the diets of some top athletes. Some of their meals could surprise you.
Crazy Calorie Count
Glassman said Olympians eat a lot of food- quantities that for ordinary people would constitute pigging out. One secret of swimmer Michael Phelps’ astonishing performance in the 2008 Olympics in Beijing was consuming as many as 12,00 calories in one day.
Athletes can eat like this and not gain any weight because their workouts are intense. According to Glassman, Phelps’ workouts can burn 4,000 to 6,000 calories in a day, and those calories must be added in order to train the following day.
Snacking Secrets
Some athletes eat strange foods that improve their performance. Yohan Blake, the Jamaica sprinter and 100-meter world champion, has stolen champion sprinter Usain Bolt’s thunder on the track during the Olympic trials. Asked about how he gets his energy, Blake answered that he eats 16 bananas per day ,Glassman said.
Jonathan Horton, the lead gymnast on the Us team, has a blood sugar problem. His solution is honey. When he starts to feel shaky at the gym, he takes honey to boost his energy, Classman said.
Foods for Recovery
What are the best foods to help the body recover after harsh competition?
For Olympic swimmer Ryan Lochte, the recovery meal is grilled chicken breasts with Alfredo sauce, whole-grain spaghetti and a salad with lemon juice and olive oil. Lochte, who recently cut out junk food, candy and soda, has undertaken a strength-training regimen(養(yǎng)生法)that involves flipping tractor tires, and tossing beer kegs, Glassman said.
【小題1】What’s the best title of this passage?

There are new findings that not enough sleep may cause people to gain weight. Researchers say a lack of sleep can produce hormonal(激素的) changes that increase feelings of hunger.
In one study, researchers in the United States examined information on more than 1000 people. The people had taken part in a long-term study of sleep disorders.
Some people slept less than five hours a night. They had 15 percent higher blood levels of a hormone called ghrelin than people who slept eight hours. And they had 15 percent less of the hormone leptin. Experts say ghrelin helps make people feel hungry; leptin makes you feel full.
The scientists say these hormonal changes may be a cause of obesity in Western societies. They note the combination that sleep limitation is common and food is widely available.
The results were not affected by how much people exercised. People who are awake longer have more time to burn energy. But the researchers say loss of sleep may increase hunger especially for high-calorie foods, so people gain weight. It seems that, for survival, the body may be designed to store more fat during times with less sleep.
Researchers from Stanford University in California and the University of Wisconsin did the study. They found that the best amount of sleep for weight control is 7.7 hours a night.
The Public Library of Science published the findings in its journal Medicine . Internet users can read the full study, free of charge, at plos. org.
【小題1】Not enough sleep can cause obesity by ______.
A.burning more of your energy |
B.making you want to eat more food |
C.keeping you from doing exercise |
D.helping you feel great without food |
A.make a news report |
B.offer a piece of medical advice |
C.make an advertisement |
D.keep a record of the old findings |
A.Only on the Internet |
B.only in Medicine |
C.Both on the Internet and in Medicine |
D.Neither on the Internet nor in Medicine |
