“…19,40 Clinical pilot studies that mainly aimed to promote more modest weight-loss expectations have been conducted previously. 11,21 These interventions were effective in producing more realistic expectations while they did not facilitate a better long-term weight-loss maintenance. It might be suggested that to be successful, interventions focusing on more modest weight losses should also include components aiming at improving body image and eating behaviors.…”

“…On the other hand, previous pilot studies aiming at changing weight-loss expectations were generally effective in producing more realistic weight-loss expectations at the end of the intervention, without however enhancing weight-loss maintenance. 11,21 Inconsistent results reported in the literature therefore stress the relevance to understand better factors related to patient's weight expectations.…”

et al. 2007

Objective: To examine associations between defined weight expectations and anthropometric profile and to identify psychological and eating behavioral factors that characterize women having more realistic weight expectations. Methods: A nonrandom sample of 154 overweight/obese women completed the 'Goals and Relative Weight Questionnaire', which assessed four weight expectations: (1) dream weight (whatever wanted to weight); (2) happy weight (would be happy to achieve); (3) acceptable weight (could accept even if not happy with it); and (4) disappointed weight (would not view as a successful achievement). Psychological assessments evaluated dysphoria, self-esteem, satisfaction with one's body (i.e., body esteem) and weight-related quality of life. The 'Three-Factor Eating Questionnaire' assessed eating behaviors: (1) cognitive dietary restraint (control of food intake), (2) disinhibition (overconsumption of food with a loss of control), and (3) susceptibility to hunger (food intake in response to feelings and perceptions of hunger). Results: Women's expectations for their dream (60.676.0 kg), happy (65.276.4 kg) and acceptable (67.976.8 kg) weights corresponded to higher percentages of weight loss (24.276.6% or 19.877.1 kg, 18.675.8% or 15.276.0 kg and 15.275.7% or 12.675.8 kg, respectively) than goals recommended for overweight individuals. Defined weight expectations were positively associated with current weight and body mass index (BMI; 0.37prp0.85; Po0.0001). When women were matched one by one for their current BMI, but showing different happy BMI, women with a more realistic happy BMI were older (P ¼ 0.03) and were characterized by a greater satisfaction towards body weight (P ¼ 0.04), a higher score for flexible restraint (P ¼ 0.003) and a lower score for susceptibility to hunger (P ¼ 0.02) than women with a less realistic happy BMI. Conclusion: These findings suggest that having more realistic weight expectations is related to healthier psychological and eating behavioral characteristics.

“…Wadden et al 5 found that informing participants, both verbally and in writing, of the weight losses they could realistically expect to achieve with pharmacological and behavioral treatment resulted in significantly smaller, but still unrealistic, expectations. Foster et al 13 and Ames et al 11 tested more comprehensive cognitive-behavioral programs and found that these treatments were effective for reducing weight loss expectations but not for improving weight loss or maintenance.…”

“…Other investigators, however, have failed to observe adverse effects of large weight loss goals. Such goals were either unrelated to weight loss 5,[10][11][12] or were associated with slightly greater losses. 4 In contrast to Dalle Grave et al, 9 Foster et al 1 found no relationship between weight loss goals and attrition from treatment.…”

The role of patients' expectations and goals in the behavioral and pharmacological treatment of obesity

et al. 2007

Objective: To investigate weight loss expectations and goals among obese treatment seekers and to examine the relationships of these expectations and goals to treatment outcomes. Method: Participants were 180 obese men and women (age 43.8710.1 years; body mass index 37.674.2 kg/m 2 ) who received one of four-year-long treatments that combined behavioral and pharmacological methods. Before treatment, they reported the amount of weight they realistically expected to lose after 4, 12, 26 and 52 weeks of treatment, as well as their ultimate weight loss goals. Expectations and goals were compared across treatment groups and examined in relation to previous weight loss efforts, weight loss and regain in treatment, attrition, satisfaction with treatment and mood. Results: Participants in all treatment groups expected reductions at week 52 that were significantly greater than the 5-15% of initial weight they were told was realistic and significantly more than they had ever lost before. Weight loss expectations were unrelated to achieved weight loss in all groups but one, in which greater expectations were associated with greater losses. Failure to meet weight loss expectations for the first 26 weeks of treatment was related to lower satisfaction ratings, but was not related to weight regain or attrition over the next 26 weeks. Symptoms of depression were reduced from baseline, regardless of whether participants achieved or failed to achieve their expected weight losses. Conclusion: Across groups, we observed no negative consequences of having (and failing to meet) unrealistic expectations for weight loss.

“…A study of recovery from relapse among successful weight maintainers showed that of those who regained Ն5% of their post-loss weight in 1 year, only 13% re-lost at least half of their weight gain in the next year, and only 5% returned to their post-loss weight or below in the next year. 9 To examine potential factors responsible for the rise in obesity, studies have explored the characteristics of normal weight, overweight, and obese individuals, 10 described weight loss experiences and expectations, 11,12 examined trends in population weight gain by sociodemographic group, [13][14][15] and examined qualitative differences between weight maintainers and regainers. 16 Less research has focused on who is at risk for weight regain after weight loss and how to prevent it.…”

Background: Relatively few studies have focused on who is at risk for weight regain after weight loss and how to prevent it. The objectives of this study were to determine the prevalence and predictors of weight regain in U.S. adults who had experienced substantial weight loss. Methods:Data were analyzed from the 1999 -2002 National Health and Nutrition Examination Survey (NHANES). This study examined U.S. adults aged 20 -84 years who were overweight or obese at their maximum weight (body mass index Ն25) and had experienced substantial weight loss (weighed 10% less than their maximum weight 1 year before they were surveyed) (nϭ1310). Results:Compared to their weight 1 year ago, 7.6% had continued to lose weight (Ͼ5%), 58.9% had maintained their weight (within 5%), and 33.5% had regained weight (Ͼ5%). Factors associated with weight regain (vs weight maintenance or loss) included Mexican American ethnicity (versus non-Hispanic white) (odds ratio [OR]ϭ2.0; 95% confidence interval [CI]ϭ1.3-3.1), losing a greater percentage of maximum weight (Ն20% vs 10% to Ͻ15%) (ORϭ2.8; 95% CIϭ2.0 -4.1), having fewer years since reaching maximum weight (2-5 years vs Ͼ10 years) (ORϭ2.1; 95% CIϭ1.2-3.7), reporting greater daily screen time (Ն4 hours vs 0 -1 hour) (ORϭ2.0; 95% CIϭ1.3-3.2), and attempting to control weight (ORϭ1.8; 95% CIϭ1.1-3.0). Finally, weight regain was higher in those who were sedentary (ORϭ1.8; 95% CIϭ1.0 -3.0) or not meeting public health recommendations for physical activity (ORϭ2.0; 95% CIϭ1.2-3.5).Conclusions: How to achieve the skills necessary for long-term maintenance of weight loss in the context of an obesogenic environment remains a challenge.
