Participants
Participants were recruited from the Quebec City metropolitan area through media advertisements. A total of 194 women were met for a screening interview and a sample of 144 premenopausal women voluntarily agreed to participate in the research project and to be randomized into one of the three groups under study. Inclusion criteria included women with overweight or obesity (body mass index [BMI] between 25 to 35), with a stable body weight for at least 2 months (±2.5 kg). All women were also
Results
Women who participated in the study had a mean age of 42.3±5.6 years. Almost all (99.3%) women of the total sample were white, and 23% were taking medication (the most common being thyroid agents [n=8]). However, these medications had no potential effects on dependent variables measured. Baseline comparisons between completers and non-completers at 16 months showed no significant differences with regards to age, BMI, metabolic variables, and eating behaviors. Furthermore, as presented in Table 1
Discussion
Our study aimed to examine the long-term effects of an HAES intervention in comparison to an SS intervention and a control group. It was found that scores for susceptibility to hunger were significantly lower at 1-year follow-up in both the HAES and SS groups when compared to the control group. In addition, situational susceptibility to disinhibition was significantly lower at 1-year follow-up in the HAES group than in the control group. Overall, these results suggest that, when compared to a
Conclusions
Results from this study showed that women involved in an HAES intervention experienced sustainable improvements in eating behaviors related to disinhibition and hunger, when compared to a control group. In addition, the role of social support appears to be an important factor to consider with regard to eating behavior changes, because no distinctive effects were observed between the HAES and the SS groups. However, significant associations were observed between eating behaviors changes and body

2022, Body ImageCitation Excerpt :‘Flexible restraint’ was a phrase of particular interest in this analysis (Leblanc et al.; 2012; Provencher et al., 2007; Provencher et al., 2009). Defined by Westenhoefer et al. (2013, p. 69) as “a more graduated approach to losing weight in which “fattening” foods are permitted in limited quantities rather than avoided entirely, leading to more consistent and sustainable dieting”, “flexible restraint” can be understood as an oxymoronic concept, in that ‘flexible’ expresses freedom of choice, personalised health and a gentle approach to health, in line with the HAES® model, whereas ‘restraint’ indicates rigidity and restriction that is characteristic of normative, weight-centric approaches to health such as strict dieting and exercise regimes (Provencher et al., 2009, p. 1856; Westenhoefer, 2013, p. 69). The use of these words together may be an attempt to award the disciplined and rigid practices of dieting and exercise regimes the social good of being considered ‘gentle’, ‘nurturing’ or ‘easy-going’.
