Eatit's Obesity Intervention: Effects on Weight, Eating Habits and Health

Prior treatment

• Ongoing substance abuse (alcohol, narcotics, or medication) is a contraindication for participation and requires specialized addiction care.
• Depression under psychiatric care: Ask follow-up questions about what support the person is receiving and his or her current mental state.
• Bipolar disorder: Ask follow-up questions about what support the person is receiving and his or her current mental state.
• High degree of psychiatric comorbidity has in some studies been shown to be a complicating factor, and this should also be considered at the start of treatment. Ask follow-up questions about what support the person is receiving and his or her current mental state.

Other illness

• Medical conditions: Patients with conditions where weight loss or weight gain may worsen the disease are excluded. For example: cancer or chronic obstructive pulmonary disease, COPD.
• Untreated or ongoing eating disorder (bulimia nervosa, binge eating disorder, anorexia, atypical anorexia, ARFID) should be treated in a specialized eating disorder unit.
• Severe psychiatric illness (such as psychosis or schizophrenia) without ongoing support.
• Suicidal behavior or self-harm in the past six months. Acute mental illness requires immediate and specialized interventions.
• Requires individual assessment. Certain conditions require individual evaluation as they may negatively affect treatment outcomes. This means that the treating dietitians should ask follow-up questions to ensure that participation in the program is feasible.
• Symptoms of binge eating not meeting criteria for binge eating disorder: Ensure that the person is willing to work with the program, not skip meals, and will inform you if the binge eating worsens.
• Exhaustion syndrome/stress: Ask follow-up questions to determine whether treatment is feasible at this time or if the patient needs to manage the stress in other ways first.
• Neuropsychiatric disorders: To benefit from the program, sufficient concentration ability and capacity for structure/planning in daily life are required. In case of a neuropsychiatric diagnosis, follow-up questions should be asked about whether the person believes that he or she can manage texts and tasks that take approximately 2-3 hours per week.

Other

• BMI: Patients with BMI \< 27 are excluded from treatment.
• Multimorbidity: Individuals with extensive comorbidities may have complex healthcare needs requiring more comprehensive medical support than Eatit can provide.
• Untreated depression may hinder participation in the program and should be managed with medical or psychological support.
• Severe sleep problems: Sleep deprivation may lead to increased appetite and reduced cognitive capacity, making it difficult to engage with treatment. Ask follow-up questions about possible undiagnosed sleep apnea or potential need for other care to address the sleep problems.

  • Has central obesity, defined as waist circumference \> 80 cm for women or \> 94 cm for men.
