Dietary Advice on Prescription in Kungsbacka

The aim of the study is to evaluate self-reported adherence to and the effects of an intervention model consisting of individualized prescribed dietary advice (DAP) in combination with Motivational Interviewing (MI), social support and mobile services in obese patients in primary health care.
