Abstract
This study examined whether changes in psychological dimensions of eating behavior during the first year of lifestyle intervention would mediate the effects of intervention on body weight during a 9-year period. Middle-aged participants (38 men, 60 women) with overweight and impaired glucose tolerance (IGT) were randomized to an intensive lifestyle intervention or a control group. During the first year, the intervention group showed increased cognitive restraint of eating and greater weight loss compared to the control group. These differences persisted for nine years. First-year increases in cognitive restraint mediated the intervention's impact on 9-year weight loss. Intensive, individually tailored lifestyle intervention had long-lasting effects on eating behavior and body weight.
