Deborah Cohen is a senior natural scientist at the Rand Corp and the author of the book A Big Fat Crisis: The Hidden Forces Behind the Obesity Epidemic and How We Can End It. According to the book, there are lots of misunderstandings of obesity.

1).If you're obese, blame your genes.

    Obesity rates have increased. Yet, between 1980 and 2000, the number of Americans who are obese has doubled—too quickly for genetic factors to be responsible.

    At restaurants, a dollar puts more calories on our plates than ever before, because restaurant meals usually have more calories than what we prepare at home, so people who eat out more frequently have higher rates of obesity than those who eat out less.

2).If you're obese, you lack self-control.

    Research shows that if we are faced with too much information, we have a tendency to make poor dietary choices. Our world has become so rich in temptation that we can be led to consume too much in ways we can't understand. Even the most vigilant (警觉的) people may not be up to the task of controlling themselves.

3).Lack of access to fresh fruits and vegetables is responsible for obesity.

    Although the US Department of Agriculture estimates that fewer than 5 percent of Americans live in the “food deserts”, about 65 percent of the nation's population is overweight or obese. For most of us, obesity is not related to access to more fresh fruits and vegetables, but to the choices we make in supermarkets.

4).The problem is not that we eat too much, but that we don't exercise.

    Michelle Obama's “Let's Move” campaign is based on the idea that if kids exercise more, childhood obesity rates will decrease. But there was no significant decrease in physical activity levels as obesity rates climbed in the 1980s and 1990s. In fact, although a drop in work-related physical activity may account for up to 100 fewer calories burned, leisure physical activity appears to have increased. The problem is that we eat too much.

    You probably know you should say” please” and “thank you ” at restaurants. You probably know the rules of a library. You know you should respect and be nice to your classmates. But do you have music manners?

    Keep It Down! You have to notice the volume of your music. You should not play your music so loud that everyone around you can hear it. Some people might even get angry. Usually, when you play the music loud on an MP3 player, other people can't hear the words of the song. They just hear a loud sound. Not one wants to listen to this. Very loud music can also be bad for your ears, so even if you are alone when listening to our MP3 player, you shouldn't have it turned up too high.

    Take Them Off! You need to know when to turn your MP3 player off and put it away. Libraries and schools don't allow MP3 players. There are other places, like museums, that don't have rules, but it would be rude to have your MP3 player on. Sometimes, it just doesn't make sense（没意义） to listen your MP3 player at event. Why would you listen to music at a play, a movie or a sporting event? You would miss what is going on and others would wonder why you even came.

    Take One Out! Once in a while it's okay just to take out one earphone and not the other. Imagine you are listening to your MP3 player when someone asks you the way. It would not be rude to take out one earphone, tell him the way, and put back the earphone and continue listening. You can also do this when you order food at a fast-food restaurant.

    It's Your Choice! There are times when you need to decide what is best. For example, some people can listen to music on their MP3 Players when read books, while others think it is disturbing. In cases like this, you need to do what seems right for you.

    Google's new camera, called Clips, is a small, smart device. It comes with a case that has a clip (夹子)，but it's not designed to be worn on your clothing. Most interestingly, it uses artificial intelligence to take photography out of your hands so it can capture moments on its own.

    This roughly 2-inch by 2-inch camera, with a three-hour battery life and Gorilla Glass for toughness, is intended for candid moments, like when a child does something cute that may happen too quickly for you to pull out your smartphone.

On board the Clips device, it uses machine learning algorithms (计算程序) to help capture scenes. Those algorithms include face recognition. “Once it learns that there's a face you see frequently, it'll try to get nice photos of those faces,” said Juston Payne, the device's product manager. And they also want it to recognize facial expressions, which involved “training it to know what happiness looks like”. The Google team also trained it to recognize what not to shoot — like when a child's hand is over the lens, or if it is tossed in a dark purse.

    The only way to see the images is by connecting the camera with your phone, as it has no screen for viewing or editing.

    Were people concerned it could seem strange? Yes, Payne admitted. But they said they addressed that by making it obvious what it is. A green light on the front signals that it is on. Besides, unlike a camera meant to monitor your home, it is not connected to the Internet.

    “This product is only possible because of the way that silicon has advanced” Payne said, noting that it was only in the past year or so that they could squeeze the technology down into a device this size. Going forward, we're likely to get more assistance from the artificial intelligence packed into our apps and gadgets.

    Breakfast is not only the most important meal of the day, but also the most neglected. Common reasons for not eating breakfast include lack of time, not feeling hungry, traditional dislike for breakfast, and dieting.

    Breakfast simply means "break 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 calories needs for the day. On average(平均)we eat 400 less calories for breakfast than for dinner. If breakfast doesn't attract you in the morning, try eating a lighter for the breakfast in the morning.

    If you aren't hungry in the morning, start with something small like juice or toast or have a nutritious mid-morning snack alter when you are hungry.

    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 eat more. That's because your body is working all day long, in fact, 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 quickly. If you feed your body healthy snacks and meals through the day, you are less likely to become hungry and fill yourself as soon as you begin to eat. Since breakfast is the first and most important meal of the day, choosing the right fuel is important. The best breakfast foods are fruits, juice, lean meat, and grain products such as bread, rice, noodles and cereals(谷物).

    The secret to living longer could be as simple as picking up your walking pace, according to a new study. Researchers from the University of Sydney found that walking at a brisk (快的) or fast pace was associated with a risk reduction of 24 percent for any cause of death.

    This effect was even more obvious in older age group, with fast walkers over the age of 60 reducing their risk of death by a surprising 53 percent. Professor Emmanuel Stamatakis, who led the study, explained, "A fast pace is generally five to six kilometers per hour, but it really depends on a walker's fitness levels; an alternatives indicator is to walk at a pace that makes you slightly out of breath or sweaty."

    In the study, the researchers looked at the results of 11 surveys from 1994 to 2008, in which participants recorded their walking pace, as well as age, sex and BMI. The analysis showed that walking at an average pace was associated with a 20 percent risk reduction for all-cause mortality (死亡率) compared with walking at a slow pace, while walking at a brisk or fast pace was associated with a risk reduction of 24 percent.

    The researchers hope the findings will encourage the development of public health message about the benefits of walking pace. Professor Stamatakis added, "These analyses suggest that increasing walking pace may be a straightforward way for people to improve heart health and risk for premature mortality—providing a simple message for public health campaigns to promote.

    "Especially in situations when walking more isn't possible due to time pressures or a less walking-friendly environment, walking faster may be a good option to get the heart rate up—one that most people can easily add to their lives."
