a. Age 21-50 years required at study entry.

b. BMI 30-39.9 required to meet study eligibility.

c. Current (within past year) non-smoker required to meet study eligibility.

d. EAT-26 measures general eating disorder pathology; score ≥ 20 was criteria for study exclusion.

e. Three Factor Eating Questionnaire, dietary restraint score ≥ 14 was criteria for study exclusion.

f. Meeting ≥ 3 of 5 NCEP-ATPIII criteria.

* Demographic characteristics were not significantly different at baseline among randomly assigned preload groups based on Chi-square test of independence for categorical variables and one-way ANOVA for continuous variables.
