Can a short online course tame binge eating? new study aims to find out

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Adults aged 18 years or older. * Overweight or obesity, based on self-report. * At least three binge-eating episodes in the past 30 days, associated with psychological distress. * The presence of chronic medical conditions commonly associated with overweight or obesity (e.g., hypothyroidism, hyperthyroidism, dyslipidemia, hypertension, type 2 diabetes mellitus, or polycystic ovary syndrome) is permitted, provided that such conditions are medically stable. * If present, chronic medical conditions must be medically stable, defined as: * stable medical treatment for at least 12 weeks, * no recent changes in medication, * no acute clinical decompensation or recent major cardiovascular events, * at least one related medical follow-up visit in the past 12 months. * If present, psychopharmacological treatment must be stable, defined as no changes in medication type or dosage during the 12 weeks prior to enrollment. * Daily access to the internet and to a computer or smartphone that allows participation in online sessions and assessments. Exclusion Criteria: * Current compensatory behaviors associated with binge eating, such as self-induced vomiting and/or regular use of laxatives, within the past 60 days. * Pregnancy or breastfeeding at the time of the initial assessment. * History of bariatric surgery. * Active suicidal ideation * Current symptoms consistent with severe mental disorders, such as psychotic disorders, bipolar disorder, complex post-traumatic stress disorder, or severe personality disorders, when associated with marked functional impairment or the need for specialized or higher-intensity clinical care. * Current substance use pattern that, due to its severity or functional impact, requires specialized clinical treatment. * Ongoing psychological and/or nutritional treatment at the time of enrollment, defined as regular sessions or an active treatment plan, regardless of treatment focus or therapeutic approach. * Presence of active or medically unstable conditions, characterized by clinically significant symptoms, lack of medical follow-up, or recent changes in medication, that could interfere with participation in the intervention or substantially affect eating behavior or mood. * Significant functional impairment that, in the clinical judgment of the research team, would limit the participant's ability to engage safely and consistently in the intervention.
