Why Employers' Incentives For Weight Loss Fall Flat With Workers

Promising workers lower health insurance premiums for losing weight did nothing to help them take off the pounds, a recent study found. At the end of a year, obese workers had lost less than 1.5 pounds on average, statistically no different than the minute average gain of a tenth of a pound for workers who weren't offered a financial incentive to lose weight.

"Our study highlights some of the weaknesses" of workplace wellness programs, said Dr. Mitesh Patel, assistant professor at the University of Pennsylvania's Perelman School of Medicine and the study's lead author.

The study, published in January's issue of the journal Health Affairs, reported the results of a yearlong randomized controlled trial to test the effectiveness of financial incentives to encourage weight loss among 197 obese employees of the University of Pennsylvania health system.

Participants were asked to lose 5 percent of their weight. Each was assigned to one of four study groups. The control group wasn't offered any financial rewards. The three other groups were offered an incentive valued at $550.

People in one group were told they would begin receiving health insurance premium discounts biweekly immediately after reaching their weight-loss goal. In another group, the people were told they would receive biweekly premium adjustments the following year if they reached their goal. Volunteers in the final group were eligible for a daily lottery payment if they met their daily weight loss goal and weighed in the previous day.
