1. Introduction

The theories most used in lifestyle interventions with good scientific results are Social Cognitive Theory (SCT), Theory of Planned Behavior (TPB), The Health Belief Model (HBM) and the Trans-Theoretical Model (TTM) (Salwen-Deremer et al., 2019). However, other behavior change theories exist, but they are not widely supported according to the latest research, so their results cannot be generalized (Salwen-Deremer et al., 2019).
