著名的饱受争议的迪康减肥法（Dukan Diet）创始人法国营养学家迪康（Pierre Dukan），日前在其新书中提出，可以通过给变瘦的孩子增加额外考试成绩的方法来解决儿童肥胖问题。

Pierre Dukan, the nutritionist behind the popular but controversial Dukan diet, has suggested that France tackle child obesity¹ by giving extra exam marks for slimness.

Dukan, who has sold 8 million copies of his diet book worldwide, made the proposal in a 250-page book called 'An Open Letter to the Future President', which he sent out Tuesday to 16 candidates for France's presidential election.

The plan calls for high school students to be allowed to take a so-called "ideal weight" option in their final year exams, the "baccalaureat（高中毕业会考） ," under which they would earn extra points if they kept a body mass index (BMI) of between 18 and 25.

Those already overweight at the start of the two-year course would score double points if they managed to slim down over a period of two years.

"It's a fantastic motivator," Dukan told the reporters.

"The baccalaureat is really important in France. Kids want to get it, their parents want them to even more, so why not get them to work together on nutrition?"

Weight gain is becoming an increasing problem in France and experts say sedentary lifestyles and poor nutrition are to blame.

World Health Organization (WHO) figures show 50.7 percent of the population were overweight in 2010, including 18.2 percent classed as obese².

"There's a real problem. Since the 1960s the number of overweight people in France has risen from 500,000 to 22 million and it's going up every year," Dukan said.

"When you reach those levels, it's no longer a health problem, it becomes a political problem, and the leaders of the nation need to worry about it."

As well as the suggestion for students, Dukan's book, which will hit French bookshops Thursday, contains a further 119 suggestions for the future president on ways to fight obesity.

One idea is the creation of a French fast-food restaurant serving more nutritional³ versions of the ubiquitous（普遍存在的） burgers and fries.

Dukan has earned an international reputation as diet guru（领袖，专家） to the stars, although his methods have drawn⁴ criticism from some health experts and weightwatchers who say his high-protein meal plan causes fatigue⁵, bad breath and dizziness. But he is also a committed campaigner for the promotion⁶ of healthier lifestyles.

He recently met executives from McDonald's France with a suggestion for a healthy "McDukan" burger, made with low-fat meat and with oatmeal（燕麦粥） bread instead of the usual white bun. Unfortunately, the giant food chain turned him down.

"They were interested, but they said the public wasn't quite ready for it yet," he said.

The BMI, obtained by dividing a person's weight by the square of their height, is used as an indicator⁷ of the proportion of body fat. The WHO defines a BMI of 18.5 to 25 as normal, 25 to 30 as overweight, and over 30 as obese.
