Obesity should be defined by a person's health—not just their weight, says a new Canadian clinical guideline. It also advises doctors to go beyond simply recommending diet and exercise. Instead, they should focus on the root causes of weight gain and take a holistic(整体的) approach to health.

Ximena Ramos-Salas, one of the guideline's authors, said research shows many doctors discriminate(歧视) against obese patients, and that can lead to worse health outcomes regardless of their weight. "The weight bias(偏见)is not just about believing the wrong thing about obesity, " she told the BBC. "The weight bias actually has an effect on the behaviour of healthcare doctors. "

Although the latest advice still recommends using diagnostic(诊断的)criteria like the body mass index (BMI) and waist circumference, it admits their clinical limitations and says doctors should focus more on how weight affects a person's health. Small reductions in weight, of about 3%-5%, can lead to health improvements and an obese person's "best weight" might not be their "ideal weight" according to the BMI, the guideline says.

It emphasizes that obesity is a complex, chronic condition that needs lifelong management. "For a long time we've associated obesity as a lifestyle behaviour. It's been a lot of shame and blame before, " Ms Ramos-Salas says. "People living with obesity need support like people living with any other chronic diseases. " But instead of simply advising patients to "eat less, move more", the guideline encourages doctors to provide supports along the lines of psychological therapy(治疗), medication and bariatric surgery like gastric bypass surgery(胃分流手术).

The guideline doesn't completely give up standard weight-loss advice. "All individuals, regardless of body size or composition, would benefit from adopting a healthy, well-balanced eating pattern and engaging in regular physical activity, " it says.

Art and science may seem like opposite things. One means the creative flow of ideas, and the other means cold, hard data—some people believe. In fact, the two have much in common. Now, a study finds art can help students remember better what they learned in science classes.

Mariale Hardiman, an education specialist at Johns Hopkins University, noticed that students who used art in the classroom listened more carefully. They might ask more questions. They might volunteer more ideas. What's more, students seemed to remember more of what they had been taught when their science lessons had involved(涉及) art. To prove that, Hardiman teamed up with some researchers and six local schools.

In the experiment, the researchers worked with teachers in 16 fifth-grade classrooms. They provided traditional science lessons and art-focused ones. In a traditional science class, for example, students might read aloud from a book. In the art-focused one, they might sing the information instead.

The team randomly assigned(随机分配) each of the 350 students to either a traditional science classroom or an art-focused one. Students then learned science using that way for the whole unit—about three weeks. When they changed to a new topic, they also changed to the other type of class. This way, each student had both an art-focused class and a traditional one. Every unit was taught in both ways, to different groups of students. This enabled the researchers to see how students did in both types of classes.

The team found that students who started off in traditional classes performed better after they moved into an art-focused class. But those who started in an art-focused class did well even when they went back to a traditional science class. These students appeared to use some of the art techniques(技巧) after going back to a traditional class. Classroom teachers reported that many students continued to sing the songs that they learned after finishing the unit. "The more we hear something, the more we retain it, " Hardiman said. "It suggests that the art may help students apply creative ways of learning on their own. "

We live in a town with three beaches. There are two parks less than 10 minutes' walk from home where neighbourhood children gather to play. However, what my children want to do after school is pick up a screen—any screen—and stare at it for hours. They are not alone. Today's children spend an average of four and a half hours a day looking at screens, split between watching television and using the Internet.

In the past few years, an increasing number of people and organisations have begun coming up with plans to counter this trend. A couple of years ago, film-maker David Bond realised that his children, then aged five and three, were attached to screens to the point where he was able to say "chocolate" into his three-year-old son's ear without getting a response. He realised that something needed to change, and, being a London media type, appointed himself "marketing director for Nature". He documented his journey as he set about treating nature as a brand to be marketed to young people. The result was ProjectWildThing, a film which charts the birth of the Wild Network, a group of organisations with the common goal of getting children out into nature.

"Just five more minutes outdoors can make a difference, " David Bond says. "There is a lot of really interesting evidence which seems to be suggesting that if children are inspired up to the age of seven, then being outdoors will be a habit for life. " His own children have got into the habit of playing outside now:"We just send them out into the garden and tell them not to come back in for a while. "

Summer is upon us. There is an amazing world out there, and it needs our children as much as they need it. Let us get them out and let them play.

You just came back from lunch so you know you can't be hungry. Yet, you are reaching for a bag of chips or a bar of chocolate as you prepare to work on a project which has been causing you stress and anxiety.

Most of us tend to overeat when we're feeling stressed or under a lot of pressure. When under long periods of stress, our bodies produce cortisol, a hormone (荷尔蒙) that causes hunger.  In addition, the hormone causes our bodies to react favorably when we consume (消耗) foods that are high in fat or sugar, or both. These foods, known as comfort foods, do control stress in the short term, which explains why many of us desire for them.

Stress eating may be a conscious (有意识的) or unconscious decision, but it does pose (引起) several problems.

Consuming an unnecessary number of unhealthy foods that are high in fat and sugar will contribute to weight gain.  What's worse, it can lead to various chronic health illnesses such as high blood pressure.

However, it does not actually solve your problems. Instead of looking for practical solutions to a stressful situation, your attention is focused on getting quick relief with food. These short-term relief measures may actually be translated into a long-term emotional burden and affect your mental health.

Mentalhealthconcernsaboutanxietyeating

Eating to deal with stress and anxiety can easily become an unhealthy habit and may even lead to eating disorders. If left unchecked, stress eating may progress to binge-eating disorder.  However, it is neither a healthy nor a permanent solution to a stressful situation. There are still many other methods of helping you fight stress and anxiety without sacrificing (牺牲) your physical and mental well-being.

A. That's stress eating.

B. This poses a risk of being overweight.

C. This affects a person's food preferences.

D. Stress eating can provide relief in times of stress.

E. Stress eating can provide emotional and mental comfort.

G. It doesn't work for the benefit of your body shapes in the long term, though.
