Treatment as usual
overweight or obesity
Participants in both study arms continued receiving their TAU, which is the treatment that GPs administer to patients with overweight or obesity. General practitioners usually address their actions at reducing the BMI to a normal range (i.e., <25), using personalised prescriptions for each case depending on the patient's motivation and disposition to change (e.g., psychoeducation, diet records, goal setting, etc.). In this case, the TAU included two interviews with the GP and a nurse, the development of a nutritional plan and some talks on health and nutrition, for a total of 7 sessions, one per week. A more detailed description of this approach can be found elsewhere (Morillo‐Sarto et al.,
