Colorado: Study: Exercise is More Critical Than Diet to Maintain Weight Loss

​A new study from the University of Colorado Anschutz Health and Wellness Center (AHWC) at the CU Anschutz Medical Campus revealed physical activity does more to maintain substantial weight loss than diet.

The study, which included Colorado School of Public Health epidemiology alum Dr. Danielle Ostendorf, was published in the March issue of Obesity, and was selected as the Editor’s Choice article.​

“This study addresses the difficult question of why so many people struggle to keep weight off over a long period. By providing evidence that a group of successful weight-loss maintainers engages in high levels of physical activity to prevent weight regain – rather than chronically restricting their energy intake – is a step forward to clarifying the relationship between exercise and weight-loss maintenance,” said Dr. Ostendorf, a postdoctoral fellow at the CU Anschutz Health and Wellness Center.

The findings reveal that successful weight-loss maintainers rely on physical activity to remain in energy balance (rather than chronic restriction of dietary intake) to avoid weight regain. In the study, successful weight-loss maintainers are individuals who maintain a reduced body weight of 30 pounds or more for over a year.
