Overweight and obesity are increasing and more than 50% of all people over 18 years in Sweden are overweight or obese. Main causes are changes in lifestyle habits regarding diet and physical activity. Obesity increases the risk of various diseases such as type 2 diabetes, cardiovascular disease, arthrosis and cancer; it also affects the quality of life. Losing 5-10% of body weight can improve metabolic health and quality of life. However, weight loss is difficult to achieve and especially to maintain over a longer period of time. Treatment based on cognitive behavioral therapy improves long-term outcomes. A behavioral treatment program via the Internet has been developed that contains 12 treatment modules that the patient follows for 6 months. The patient has regular contact with a therapist who follows the patient's treatment process and provides support. The purpose of this pilot study is to evaluate the Internet-based treatment regarding weight reduction, change in eating habits, physical activity and quality of life. We also intend to investigate how feasible and user-friendly the treatment program is and the patients' experiences of the treatment effects.

| Change from baseline to follow-up at 6 months and 12 months |
| Psychosocial functioning | Change in weight-related psychosocial functioning measured by the Obesity-related Problems scale, version 3 (OPv3). OPv3 comprises 26 items on a four-point response scale. The participants indicate how bothered they are by their obesity in a broad range of social activities and to what extent they avoid social activities because of their obesity. The responses are aggregated into two domains: Distress (13 items) and Avoidance (13 items). Scale scores range from 0 (no distress/avoidance) to 100 (maximum distress/avoidance). | Change from baseline to follow-up at 6 months and 12 months |
| Experiences of the treatment program | The patient's experiences of the treatment program are measured with five study-specific questions about how easy or difficult it was 1) to follow the treatment program, 2) to understand the language and content, 3) to use the program 4) to understand the home tasks and if they were relevant, and 5) how useful feedback from the therapist was . | From treatment start to follow-up after treatment ends at 6 months |
| Experiences of the treatment effects | The patient's experiences of the treatment effects are measured with study-specific questions (18 and 15 questions at 6 and 12 months follow-up respectively). The questions concern the following aspects: 1) if the treatment has been helpful in making lifestyle changes, 2) if the participant is satisfied or dissatisfied with the weight change, 3) if the participant considers that the treatment has had an effect on health and well-being. | From baseline to follow-up at 6 months and 12 months |
