Study Description

Brief Summary

The current proposal aims to investigate implicit and explicit priming paradigms for changing cue-dependent and goal-directed nutritional behavior.

Condition or Disease	Intervention/Treatment	Phase
Eating Behavior Habits	Behavioral: health mindest Behavioral: palatability mindset	N/A

Detailed Description

Food choice and intake is a daily and throughout normal subject. However, for more and more people eating habits and the question of food choice are of increasing interest and in several cases even a problem. The prevalence of obesity has tripled in the last decades and it is even spoken of an obesity epidemic. Life style interventions to lose weight often fail on the long run, also because people fall back into former unhealthy eating habits. Various factors influence our daily food choice, not all of which are apparent to ourselves. Thus, food choice might be goal-directed and therefore conscious and reflective, yet in other circumstances the choice to eat something specific might be based on cue dependent processes which are automatic and thus difficult to control. Since a change in eating-behavior and long-lasting weight loss is most problematic to achieve, the current proposal aims to investigate implicit and explicit priming paradigms for changing cue-dependent and goal-directed nutritional behavior.
