For successful weight loss, Interventions that exclusively focus on changing behaviors will be more successful if they incorporate changing habits. Strategies are required to break the unhealthy habits and/or to form new healthy habits. These new habits are generally formed by repeating a behavior until it becomes more or less automatic, forging a direct link between the context and response. A gradual shift will occur from intentional to automatic.
We make over 200 food decision a day. It is not a lack of will power or poor knowledge but the power of situations to trigger past responses. Habits keep up operating in the way we have always done, despite our best intentions to do otherwise. Breaking unwanted habits can be achieved through restructuring your environment and programming new responses.
