(Akron, Ohio) The journal, Obesity Research, today published an article on the results of a 24-month federally funded obesity study led by Summa Health System researchers in Akron, Ohio. The study is the first to document that patients who spend a longer time in the action and maintenance stages for portion control or planned exercise were more likely to lose weight. The reverse was also true. Patients who spend less time in the action and maintenance stages for portion control or planned exercise were more likely to gain weight.

According to lead Summa researcher Everett E. Logue, Ph.D., the greatest weight loss in the study was related to portion control. "Although we saw similar patterns of weight loss related to reduced dietary fat consumption, increased fruit and vegetable consumption, increased physical activity and increased planned exercise, the target behavior that induced the greatest weight loss was portion control."

While Logue points out portion control showed the greatest weight loss, the study also suggests planned exercise induced the least. This however, does not surprise Logue.

"Portion control may be behaviorally easier to change than increasing planned exercise for many obese individuals," Logue said. "However, other research suggests that planned exercise is an important component of long-term weight management."

The study found that 38 percent of obese patients who consistently spent two years practicing food portion control lost five percent or more of their baseline weight. Conversely, they concluded that 33 percent of patients who did not consistently practice portion control gained five percent or more of their baseline weight.

"The message in the study is that you have to eat fewer calories and/or burn more calories if you want to loss weight," Logue said. "There are no short cuts. However, there are multiple ways of eating fewer calories and/or burning more calories. The trick is to
