ABSTRACT The moderating influence of binge eating status on obese individuals' responses to weight loss treatment was evaluated with a meta-analysis of 36 tests of weight loss treatment (n=792) that were matched to control key background variables. After controlling for pre-treatment weight, treatment produced more weight loss in samples of obese non-BED compared with obese BED participants. Weight loss treatment produced large posttreatment reductions in depression in both obese BED and non-BED samples. The results indicate that BED status moderated post-treatment weight loss among people in weight treatment programs. Obese BED (average weight loss=1.3 kg) samples lost negligible weight compared to obese non-BED (average weight loss=10.5 kg) samples. BED status did not moderate psychological responses to treatment: both BED and non-BED samples experienced large post-treatment reductions in depression. The clinical implications of these findings are discussed.

    ABSTRACT: Le traitement médicamenteux des compulsions alimentaires chez le malade obèse est encore l’objet d’incertitudes. En effet, si quelques études contrôlées sont disponibles, elles n’ont inclus que trop peu de malades au total. Les antidépresseurs de type inhibiteurs de la recapture de la sérotonine, l’orlistat et les derniers anti-épileptiques ont fait la preuve de leur efficacité (niveau de preuve: bon), mais aussi de leurs effets secondaires, en particulier les anti-épileptiques. Ces médicaments ne sont efficaces en moyenne que chez un malade sur deux; ils n’agissent qu’après un délai d’au moins trois semaines et leurs effets persistent tant que dure leur prise. La dose efficace est en règle élevée. Leurs effets favorables sont d’autant plus importants et durent d’autant plus qu’un travail psychocomportemental a été effectué en parallèle. The effectiveness of pharmacological treatment of compulsive eating disorders in obese patients is as yet uncertain. Although some clinical trials have been carried out, not enough patients were involved in total. Antidepressants such as selective serotonin reuptake inhibitors, orlistat and the newest anti-epileptics have all been shown to be successful (proof level: good), but have also been seen to have side effects, particularly with respect to anti-epileptic drugs. On average, these drugs only work for one in two patients, they take at least three weeks to work and they only work for as long as they are being taken. They are generally only effective when taken in high doses. Their success is greater and more durable if used simultaneously with psycho-behavioral therapy.

    ABSTRACT: Binge eating (BE) is common in overweight and obese individuals with type 2 diabetes mellitus, but little is known about how BE affects weight loss in this population. To determine whether BE was related to 1-year weight losses in overweight and obese individuals with type 2 diabetes participating in an ongoing clinical trial. The Look AHEAD (Action for Health in Diabetes) trial is a randomized controlled trial examining the long-term effect of intentional weight loss on cardiovascular disease in overweight and obese adults with type 2 diabetes. A total of 5145 overweight and obese individuals aged 45 to 76 years with type 2 diabetes participated in this study. Participants were randomly assigned to an intensive lifestyle intervention or to enhanced usual care (a diabetes support and education control condition). At baseline and 1 year, participants had their weight measured and completed a fitness test and self-report measures of BE and dietary intake. Four groups were created based on BE status at baseline and 1 year (yes/yes, no/no, yes/no, and no/yes). Analyses controlled for baseline differences between binge eaters and non-binge eaters. Most individuals (85.4%) did not report BE at baseline or 1 year (no/no), 7.5% reported BE only at baseline (yes/no), 3.7% reported BE at both times (yes/yes), and 3.4% reported BE only at 1 year (no/yes), with no differences between intensive lifestyle intervention and diabetes support and education conditions (P = .14). Across intensive lifestyle intervention and diabetes support and education, greater weight losses were observed in participants who stopped BE at 1 year (mean [SE] weight loss, 5.3 [0.4] kg) and those who reported no BE at either time (mean [SE] weight loss, 4.8 [0.1] kg) than in those who continued BE (mean [SE] weight loss, 3.1 [0.6] kg) and those who began BE at 1 year (mean [SE] weight loss, 3.0 [0.6] kg) (P < .001). Post hoc analyses suggested that these differences were due to changes in caloric intake. Overweight and obese individuals with type 2 diabetes who stop BE appear to be just as successful at weight loss as non-binge eaters after 1 year of treatment. Identifier: NCT00017953.

    ABSTRACT: Obesity during youth has become a major public health problem. Overweight adolescents are at elevated risk for a variety of physical health problems and exhibit higher rates of eating pathology compared to non-overweight teens. Eating pathology has been suggested to contribute to overweight, and in some cases, complicate weight loss. A form of eating pathology common among overweight youth is binge eating. Many researchers have hypothesized that adults with binge eating may be less successful at weight loss, but this hypothesis has been met with mixed empirical support. Few adolescent studies have examined the impact of binge eating on weight loss. The present study seeks to evaluate the impact of binge eating on weight outcomes among adolescents during and after a placebo-controlled medication trial that included a behavioral weight loss program. Specifically, the present study aims to: (1) assess the impact of baseline binge and loss of control eating on weight loss and regain, (2) assess the impact of post-treatment binge and loss of control eating on weight regain, and (3) assess the impact of change in binge and loss of control eating on weight loss and regain. Findings from this study may help to guide treatment recommendations for obese adolescents.
