Weight bias and weight loss treatment outcomes in treatment-seeking adults.

Background: Few studies have explored the relationship between weight bias and weight loss treatment outcomes.

Purpose: This investigation examined the relationship between implicit and explicit weight bias and (a) program attrition, (b) weight loss, (c) self-monitoring adherence, (d) daily exercise levels and overall caloric expenditure, (e) daily caloric intake, and (f) daily caloric deficit among overweight/obese treatment-seeking adults.

Methods: Forty-six overweight/obese adults (body mass index > or = 27 kg/m(2)) participating in an 18-week, stepped-care, behavioral weight loss program completed implicit and explicit measures of weight bias.
