A recent report by the OECD suggests that by 2025, about half of high school students will be unable to go back to school because of the health consequences of obesity.
The OECD study, which examined the health and wellbeing of students across the world, found that a quarter of those with an eating disorder will have an eating problem at some point in their lives.
It said that many people have been denied access to health care for years because of weight issues, which in turn has caused an epidemic of obesity and other eating disorders in the developed world.
According to the report, more than 20 million adults worldwide have anorexia, bulimia, binge eating, or anorexic symptoms.
Many studies have found that many of these people have eating disorders, including bulimics, and have a high likelihood of having a weight problem in the future.
But the study, conducted by the National Institute for Health and Development in Geneva, Switzerland, found it was not clear if these eating disorders could be treated by a simple diet or medication.
Instead, it suggested that students should have the option of attending a primary or secondary school or university where they can be monitored and managed by a specialist dietitian or specialist dietician, who would also help them manage their weight.
This is because, it found, the health risks of obesity outweigh the health benefits, especially if people are able to lose weight at home.
In addition, it said, if people manage their eating and weight in a healthy way, it may reduce the risk of developing an eating or weight disorder in the long term.
But if there is no medical intervention, it suggests that many students will continue to be denied the option to go out to school and continue to suffer a range of health problems.
Some countries in the developing world have already taken action to help prevent obesity.
In the US, more and more students are able go to school without having to undergo a specialised diet programme.
The National School Lunch Program was created in 2009 to help students from low-income families afford meals in schools.
Students in the US have also been able to choose the type of food they eat in the cafeteria, which has resulted in some students opting for healthier fare.
Many students in the UK are now able to skip the lunch period altogether, with the school year starting earlier and lasting longer.
The UK government also announced plans in November last year to set a target of reducing childhood obesity by 40 per cent by 2020.
But it also said it was important to remember that it is not enough to tackle the problem through better education, more support for those with eating or obesity issues, or better food and exercise policies.
Professor Mark Ware, from the University of Sheffield, said it would be important to look at whether other nations are following the UK’s example and introducing programmes that encourage students to go on a healthy diet and exercise.
“If they are, we need to do more to ensure that students are not being denied access and to make sure that they are not stigmatised by having to restrict their eating or exercise options,” he said.
“It is important that we can provide opportunities for students to learn about healthy eating and exercise and to be educated about the risks associated with these activities.”
