  1. * Responses to each item of the Binge Eating Scale were given a score from 0 to 3 and summed for a possible total of 15 with higher scores indicating more episodes of binge eating behavior. Subscales of the revised Three Factor Eating Questionnaire (TFEQ-R18) (uncontrolled eating, emotional eating, restrained eating) were summed into a scale of 0–100. Higher scores reflect more uncontrolled eating, emotional eating, and restrained eating
  2. Boldface indicates statistical significance where Bonferroni correction (two-sided alpha: 0.05/3 = 0.017) was applied to adjust for multiple comparisons
  3. pa GEE comparing 12-month change in each study arm compared versus controls
  4. pb GEE comparing 12-month change in each study arm compared versus controls, adjusted for age, race/ethnicity (black, white, other), and baseline BMI
  5. pc GEE comparing 12-month change in diet alone and exercise alone arms versus diet + exercise arm, adjusted for age, race/ethnicity (black, white, other), and baseline BMI
  6. pd GEE comparing 12-month change in diet alone and exercise alone arms versus diet + exercise arm, adjusted for age, race/ethnicity (black, white, other), baseline BMI, perceived stress, anxiety, depression and social support
