The growing population of overweight and obese people calls for developing new methods and tools for independent weight management. Wellness Diary (WD), a cognitive behavioural treatment (CBT) based weight management application, was designed and implemented for Series 60 mobile phone platform. WD is a tool for recording CBT related self-observations and giving feedback on them. A three-month user study with 29 volunteer users was launched to study the acceptance and effect of the concept. The users recorded on average 5.6 (SD 0.59) self-observations to WD per day, and the recording activity was maintained at a high level throughout the study. The average weight change in the group was -1.4 kilograms (range: -12.0 - +1.5 kg, SD = 2.7 kg). The users found WD simple and easy-to-use, yet useful in weight management. The results indicate high level of acceptance for the approach and concept. The weight management results were encouraging and suggest that wellness diary concept supports success of CBT based weight management.
