Researchers led by psychologist Amy Gorin of the University of Connecticut set out to see whether they could replicate these results in a randomized controlled trial. They recruited 130 couples in which one partner was willing to try a weight-loss program and the other was not. To be included, the partner on the program had to be either overweight or obese (with a body mass index between 27 and 40) and the other partner had to be overweight (with a BMI over 25).
