Gender-sensitive Enhancement of Common Weight Loss Strategies for Overweight and Obesity

According to the SIRs the 12-week intervention will contain exercises from three out of six different key modules (e.g. self-efficacy, impulsivity). The remaining modules will be implemented as mini-modules during the end of the intervention phase. The study will be designed gender-sensitive instead of gender-dichotomous. This means that treatment contents will be individualized based on gender-related SIRs and not biological sex. Participants choose between two different styles of presentation for each module and the contents can be deepened within specific exercises.
