Researchers warned that while policy and environmental changes can be effective in preventing weight gain in populations, they do little to help overweight individuals shed the pounds.
To help people lose weight, the researchers call for "new treatments, health delivery strategies and initiatives" aimed at fighting the global obesity epidemic, George Washington University's Milken Institute School of Public Health reported.
"An estimated 600 million people worldwide now suffer from obesity, and that represents an enormous burden both for individuals and for society at large," said William H. Dietz, director of the Sumner M. Redstone Global Center for Prevention and Wellness at Milken Institute School of Public Health at the George Washington University. "Our findings suggest that we must take steps now to transform the way obesity is treated, with more emphasis on partnerships, better training for health professionals, and initiatives aimed at erasing the stigma surrounding this serious health condition."
The researchers conducted one of the most comprehensive reviews on literature published between 2000 and 2013 on obesity management. They determined current clinical delivery systems are poorly suited to fight obesity, and many healthcare professionals are not adequately trained to deal with the problem.
"Many health professionals view people with obesity as lazy or lacking in willpower," Dietz said. "The disrespect shown by some providers may discourage future visits or delay essential care that could lead to weight loss or the detection of diseases associated with obesity."
The researchers suggest training for healthcare providers should highlight the biological factors linked to obesity. They also stress that healthcare providers should remain informed on therapeutic advances for obesity, such as behavioral therapy, medications, and devices that can reduce appetite such as bariatric surgery. The researchers also suggest future efforts to tackle the problem of obesity should integrate clinical and community initiatives.
"Even a 5 to 10 percent weight loss can lead to a reduced risk of stroke, heart disease, and diabetes," Dietz said. "Health professionals should stress the benefits of modest weight loss--and work with their patients to decide on the most appropriate therapy."
The findings were published in a recent edition of the The Lancet.
