Abstract

Background & aims: Previous studies have shown improvements in eating behaviors following a Health-At-Every-Size approach (HAES). However, to our knowledge, no study has yet investigated how a HAES intervention could influence dietary intakes and eating patterns in overweight women. Therefore, objectives of this study were to determine changes in dietary intakes and eating patterns in premenopausal overweight women in response to a HAES intervention compared to a social support intervention and a control group, and then to determine whether changes in eating behaviors were associated with changes in dietary intakes and eating patterns in response to the HAES intervention.

Methods: Women completed a 3-day food record and the Three-Factor Eating Questionnaire was used to assess eating behaviors.

Results: Energy intake (main effect of time; p = 0.045) and snack frequency (main effect of time; p = 0.0004) decreased similarly over time in the three groups whereas proportion of energy intake from breakfast (main effect of time; p = 0.03) increased over time. Within HAES group, decreases in hunger and external hunger were associated with a decrease in total daily energy intake (r = 0.50, p = 0.0009 and r = 0.50, p = 0.0007, respectively).

Conclusions: HAES intervention has no specific impact on eating patterns. However, a decrease in hunger, which characterizes women who respond well to HAES, is associated with a decrease in overall energy intake. Clinical trial registration number (www.clinicaltrials.gov): NCT01240499.
