The American Medical Association has officially recognized obesity as a disease causing the spotlight to focus is own leading a healthier lifestyle.

Delegates made the decision at the association's annual meeting in Chicago.

"Recognizing obesity as a disease will help change the way the medical community tackles this complex issue that affects approximately one in three Americans," Dr. Patrice Harris, a member of the association's board, said in a statement. Harris added that the new definition would aid the fight against Type 2 diabetes and heart disease, which are linked to obesity.

Many doctors and obesity advocates believe that the decision will help focus more attention on obesity. The spotlight on the disease could help improve reimbursement for obesity drugs, surgery and counseling.

"I think you will probably see from this physicians taking obesity more seriously, counseling their patients about it," said Morgan Downey, an advocate for obese people and publisher of the online Downey Obesity Report. "Companies marketing the products will be able to take this to physicians and point to it and say, 'Look, the mother ship has now recognized obesity as a disease.' "

Reports suggest leading a healthy lifestyle starting at an early age is the best way to prevent the disease and increase life expectancy. By avoiding "junk food" and being physically active, you can maintain the ideal weight for your body type.
