It’s no secret that reading is helpful. But can it help kids lose weight In the first study to look at the influence of literature on overweight teenagers, researchers at Duke Children’s Hospital discovered that reading the right type of novel may make a difference.
The Duke researchers asked overweight girls aged 9 to 13 who were already in a weight loss program to read a novel called Lake Rescue. It was carefully created with the help of pediatric experts (儿科专家) to include specific healthy lifestyle and weight management guidance, as well as positive messages and strong role models.
Six months later, the Duke researchers found the 31 girls who read Lake Rescue experienced a significant decrease (fall) in their BMI scores (-.71%) when compared to a control group of 14 girls who hadn’t (+.05%), explained Alexandra C. Russell, a fourth-year medical student at Duke who led the study.
“As a pediatrician, I can’t count the number of times I tell parents to buy a book that might provide useful advice, yet I’ve never been able to point to research to back up my recommendations,” says Sarah Armstrong, director of Duke’s Healthy Lifestyles Program where the research took place. “This is the first probable interventional (介入的) study that found literature can have a positive influence on healthy lifestyle changes in young girls.”
Obesity(肥胖） is becoming more widespread in children, according to the CDC (Centres for Disease Control), which reports that 16 percent of children aged 6 to 19 are overweight or obese, a number that has increased since 1980. Researchers are looking at a lot of ways to help kids stay healthy, lose weight and be more active, but Armstrong says, “most don’t work very well. The weight loss choices that are effective typically involve taking powerful medications with side effects, or require long-lasting surgical procedures.”
While the BMI decrease because of the book is small, Armstrong says any decrease in BMI is encouraging because BMI typically increases in children as they grow and develop. That’s okay as long as it follows a normal, progressing curve(曲线）. In overweight kids, however, BMI usually increases more quickly. “If their BMI percentile (百分位) goes down, it means they are either losing weight or getting tall and not gaining weight. Both are seen as positive signs in kids who are trying to lose weight,” she explains.

The biggest secret about inventing is that anybody can do it! Perhaps this sounds crazy, but it’s true. Maybe you have the wrong idea about inventing, so read on to discover the truth.
Wrong idea No.1： An invention has to be something completely new.
Well, inventing means creating something “new”, but the idea could come from something that already exists*. The Wright Brothers, for example, got the idea for building a “flying machine” from watching birds.
Wrong idea No.2： Inventors are born, not made.
There are a lot of factors* that make invention possible. Take Mozart, for example. He was born with an endowment for musical composition. But other factors were also important for his creativity. His father was a music teacher, and Mozart practiced for hours every day, from the time he was four years old. Thomas Edison said that being an inventor was “99% hard work and 1% inspiration”!
Very successful creators don’t give up when they get something wrong. As one inventor said, “A failure is the right answer to the wrong question.”
Wrong idea No.3： Inventors are always old people.
Don’t believe that you can’t invent something when you are young. Here are two examples of young inventors： Louis Braille went blind when he was a child. When he was fifteen, he invented a system of reading and writing for blind people that is still used in most countries today.
As a young man, George Nissen was watching some artists performing in a show. He watched how they fell into the safety net and then jumped back up again. This gave him an idea, and he invented the trampoline*.
