“It is often said that the key to weight loss is a simple calculation - fewer calories in than out - but in reality, it is very difficult to achieve lasting weight loss. This despite more knowledge about diet and exercise in the population than ever. How does this fit together? How are people with overweight and obesity met in the health service, what treatment are they offered, and what seems to work?This conversation is led by Marianne Clementine Håheim, interest policy advisor at ROS.

The eBATTLE Obesity- study

The eBATTLE obesity study is a multicenter RCT that investigates the effect of the drug semaglutide in the treatment of severe obesity in adolescents aged 12-18 years. It is a 60-week prospective pragmatic clinical trial consisting of two phases. Phase 1 is a single-arm feasibility study of a low-calorie intervention (eLED) over 8 weeks. The second phase of the study, which starts right after eLED, is a 52-week RCT, two-armed, double-blinded multicenter study that compares semaglutide versus placebo, as an addition to a family-based cognitive behavioral therapy for obesity (25 sessions; E-BT) mainly conducted through telehealth. 220 adolescents with severe obesity will be recruited to the first part of the study, and 150 to the RCT.

EDIT-collaboration. International research collaboration on eating disorders in obesity treatment


The EDIT Collaboration is a collaboration between researchers, clinicians and users with the goal of improving treatment for people with obesity and eating disorders. There is a lack of knowledge about which factors in different interventions in obesity treatment can increase or decrease the risk of developing eating disorders. The same applies to individual characteristics that can affect the risk of developing eating disorders during and after obesity treatment. By conducting meta-analyses where data from lifestyle treatments for obesity from around the world are combined, this study tries to examine these objectives: 1) To identify characteristics of adolescents and adults with obesity that are associated with increased risk of developing eating disorders during and after obesity treatment 2) To deconstruct behavioral treatments aimed at obesity and examine whether subcomponents and strategies in the treatments increase or reduce the risk of developing eating disorders

Collaborators: The project is led by Hiba Jebeile at University of Sydney, but represents a collaboration between researchers from around the world.

Role: Contributes with data from the FABO-study to the meta-analyses, input to protocol, sits in specialist group that discusses/investigates dietary restraint as a risk factor for developing eating disorders

Cognitive behavioral therapy and emotion-focused therapy for depression. A randomized clinical trial In this study, we want to compare the effect of two treatment approaches that are in widespread use in public and private mental health care in Norway, Cognitive behavioral therapy (CBT) and Emotion-focused therapy (EFT). The comparison will be done through a randomized controlled trial. The main objective will be to investigate whether the treatment method EFT has a similar effect on the treatment of depression as CBT. There is a need for more knowledge about what works for whom in psychological treatment of depression. We lack scientific knowledge about what characterizes treatment courses that have good and bad outcomes. Increased knowledge about who benefits from what, can help to better select which patients should be offered different treatment approaches, and in this way contribute to increased cost-effectiveness and better prioritization within mental health care. In this study, we want to investigate what characterizes processes that give satisfactory and less satisfactory outcomes within and across the conditions. In the study, we will investigate treatment effect, patient experiences and change processes for patients with moderate depression who participate in the intervention "Back to work". The intervention is a short-term treatment offered in the public mental health care and is aimed at people with depression and anxiety who experience a reduction in work ability. We will collect quantitative data in the form of self-report and analysis of video recordings of therapy courses. In addition, we will collect qualitative data in the form of interviews where we map user experiences among the involved patients.

Factors that affect treatment and dropout from eating disorder treatment in specialist health care

Eating disorders often involve a lot of ambivalence and anxiety related to undergoing treatment. It is one of the mental disorders that has the highest dropout from treatment and where many go untreated for a long time. The purpose of this study is to produce knowledge that can help us understand more about dropout from treatment for eating disorders and to help develop the treatment offered so that more people with eating disorders get good help. The study consists of several parts, in order to explore the perspective of the key stakeholders in the treatment of eating disorders - patients, therapists and general practitioners. Focus group interviews will be conducted with therapists and general practitioners, individual interviews with people who have chosen to end treatment for eating disorder before it was completed. Patients and general practitioners will also be invited to fill out an anonymous survey. Data from the regional register for treatment of eating disorders will also be analyzed to see which factors predict dropout from treatment, such as comorbidity, duration of eating disorder, severity of illness and network.

Mindfulness and eating disorders

The project investigates the participants’ experiences with, and effects of, a mindfulness-based low-threshold intervention for eating disorders. The aim is to examine whether changes in problematic eating, were related to the participants’ changes in self-compassion from week to week. Further, we want to learn more about how it is to live with, and cope with, a problematic relationship with food over time, through conversation with the participants four years later. The project forms the basis for a doctoral degree for PhD fellow Anders Ohnstad, UiB.

Obesity and binge eating disorder: Prevalence, diagnosis and clinical implications

There is little knowledge about the prevalence of eating disorders among patients seeking treatment for severe obesity, and which screening tools for eating disorders work best for this group. The project will map eating disorder symptoms and symptoms of anxiety and depression in 200 patients with severe overweight who are referred to treatment for severe obesity at Haukeland University Hospital. The patients will undergo assessment with a wide range of questionnaires that address different types of eating disorder symptoms and disturbed eating behaviors that are common with obesity, as well as a comprehensive standardized clinical diagnostic interview (Eating Disorder Examination Interview). The aim of the project is to investigate the prevalence of eating disorders in adults seeking treatment for severe obesity, as well as compare the results from the different screening tools for eating disorders with the results from the clinical diagnostic interview.

How do adults with severe overweight understand their own weight development from childhood to present? A qualitative study

The purpose of the study is to investigate how people with severe overweight themselves experience and explain their weight development from childhood to present. Such knowledge is important both to increase the understanding of how obesity develops, in improving treatment options and in meeting the individual user with severe overweight in health services. 10 people with severe overweight (BMI over 35) have been recruited to the study via information to user organizations and treatment sites for severe overweight. Qualitative in-depth interviews have been conducted with informants and transcribed interview data will be analyzed using thematic analysis. Qualitative in-depth interviews are chosen as a method because we want to know more about the informants' own experience and understanding of how and why their overweight has developed. The goal is a deeper understanding of these phenomena.
