Lifestyle overhaul needed to cure obesity

Two-thirds of American adults are too fat, and a major overhaul of US policies – from schools to restaurants to urban planning is needed to stem the epidemic, medical experts said.

Two-thirds of American adults are too fat, and a major overhaul of US policies – from schools to restaurants to urban planning – is needed to stem the epidemic, medical experts said.

In a hefty, 400-plus page report, the Institute of Medicine (IOM) called for urgent action to reverse national obesity trends that are costing the US R1, 4 trillion a year in illness-related costs.

Peppered with terms like "synergies," "empower" and "systems approach," the report called for a renewed focus on schools as the place where eating habits take hold for life, noting that 17% of US children are obese, and a figure that has tripled in 30 years.

Offering lunches packed with veggies and whole grains and limiting access to sugar-sweetened drinks were among the recommendations for kids age six to 18.

Obesity a stubborn problem

States and local schools should also make sure all children and teenagers have the opportunity for 60 minutes of exercise per day, said the report titled "Accelerating Progress in Obesity Prevention: Solving the Weight of a Nation."

Other top goals for all ages included making physical activity a daily routine, making healthy food and drink choices widely available, and expanding the role of doctors, insurers and employers.

"Because obesity is such a complex and stubborn problem, a bold, sustained and comprehensive approach is needed," said the report.

"Action must occur at all levels – individual, family, community, and the broader society."

The IOM report reviewed past strategies for obesity prevention in order to come up with new recommendations to speed progress, it said.

Obesity could be catastrophic

"Left unchecked, obesity's effects on health, health care costs, and our productivity as a nation could become catastrophic," added the report.

People who belong to ethnic minorities, who have lower incomes and less education are more susceptible to obesity, partly due to policy decisions that result in limited access to healthy foods and places to enjoy exercise.

For instance, one third of children born today will develop type 2 diabetes in their lifetime, according to projections cited by the IOM.

"Some communities may have no safe place to walk or play, no shops offering affordable healthy food, and widespread advertisements of unhealthy food and beverages," said the report.

Limited ability to control weight

Community planners could work harder to make sure there are safe places for exercise, for example by converting an unused railroad bed into a running and biking trail, said the report.

"People only have a certain, limited ability to control their weight in an environment where there is a lot of food available," said IOM committee member Shiriki Kumanyika, professor of epidemiology at the University of Pennsylvania.

"One of the main reasons (for obesity) has to do with people being presented with large quantities of food – tasty food – in a culture where more is better, portion sizes are getting larger and heavily advertised," she told AFP.

Separate research presented Monday at a related conference on obesity in the US capital warned that 42% of US adults could be obese by 2030, and the number of severely obese people could more than double from five to 11%.

Invest money and political capital

Michael Jacobson, executive director of the Center for Science in the Public Interest, a consumer advocacy group, urged governments, the food and health care industries and schools to implement the IOM's recommendations, calling it an "excellent blueprint for solving America's costly obesity problem."

"But policy makers will have to invest both money and political capital to convert the advice into reality," he added.

Despite the report's repeated urging of more institutional measures to make sure healthy foods are readily available, Kumanyika said the report's authors were not seeking new laws or mandates.

"We can't rely on mandatory solutions where they are not likely to be put into place. There a lot of things that government can do voluntarily," she said.

"Many of the things we recommend are in the control of people," she added. "They just require energy, focus and leadership to get things done."
