Eligibility
Inclusion criteria
Inclusion criteria: Included are people with overweight (BMI 25 - 29.9 kg/m2) or obesity (BMI 30 - 39.9 kg/m2) grade I and II (278.00, E66.9) with pathological eating habits and/or people with Binge-Eating disorder (BED. 307.51, F50.8) by DSM-5 (APA, 2013), who want to reduce or stabilize their weight long-term. Uncontrolled overeating, grazing (atypical eating attacks), sweet eating, emotion-induced eating and/or at times strongly restricted eating behaviour within the meaning of rigide cognitive control are defined as pathological eating habits of overweight or obese people. Besides the subjects have made use of interventions of weight reduction, like autonomous dietary restraint and/or increase of physical activity, participation in conservative treatments for overweight or obesity and/or bariatric interventions as well as psychotherapeutic individual or group therapy. Thereby they failed long-term in stabilize their initial “successful” weight reduction of at least 5-10% of their beginning weight. The age is limited to 18 to 45 years, to get an almost homogeneous group concerning the training of cognitive functions. The subjects should possess adequate knowledge of German and access to the Internet.
Exclusion criteria
Exclusion criteria: The subjects aren’t participating currently in other psychotherapeutic individual or group therapies. Furthermore exclusion criteria are Bulimia nervosa, Schizophrenia spectrum and other psychotic disorders, Substance-related and addictive disorders not in early or sustained remission, Neurocognitive disorders, Intellectual disabilities and severe untreated Borderline personality disorder by DSM-5 (APA, 2013) as well as acute suicidality. In case of severe physical diseases which could influence strongly the eating behavior (amongst others liver disease, diabetes mellitus, thyroid dysfunction), subjects were excluded on a case-by-case basis. Besides pregnant women can’t participate because of hormonal and physical changes and their potential influences on the measurements. Medication-induced weight gain, e.g. due to regular intake of weight loss drugs, lithium, weight-influenced antidepressants, lithium, methylphenidate, zyprexa, valproic acid, cortisone as well as sedatives, will carefully be considered in each individual case, depending on the effect size there can be an exclusion of subjects.
