  1. Eating Behaviour Explanations for the success or failure of dieting.

  2. Notice I said explanations.. • You will need to identify and explain several reasons why a diet may fail or succeed. • There are several, you may want to work on recalling at least two.

  3. But before we look at the reasons.. • What research methods are likely to have been used to collect this data? • Twin studies • Adoption studies • Correlational analysis • Questionnaires. • Keep in mind we need to constantly keep these crucial pieces of information to aid our AO2 and help with AO3.

  4. So…what is a workable definition of dieting???? • The adoption of a particular or special diet in order to achieve a purpose. (A2 level psychology,2009) A common opinion is dieting in the short term to lose weight fast is not as successful as those who take their time and lose weight slowly but surely. Diets usually take the form of reduced calories (lower than normal) to achieve slimness and or being more attractive. In Britain in the last 25 years 22% of adults are considered obese & 75% overweight (Lopez-Jimenez, 2008)

  5. So what are some of the common reported reasons for failure/success. • Leptin & Insulin • Life events • Operant conditioning. • Motivational style • Exercise. • Underestimate/Overestimate • Social factors • Restrained eater • Denial

  6. Restrained eaters?? • Ruderman & Wilson (1979) • Used what is known as the preload/taste-test procedure to explore eating behaviour in a lab setting. • The Ps given either a high-cal shake or chocolate or a low cal preload (e.g. cracker) • The Ps were asked to participate in a taste test were they were asked to rate a series of diff foods (biscuits) for a variety of qualities, incl: salt/sweet. • The Ps were then left alone for a fixed period to rate food and the amount they ate was also recorded.

  7. Ruderman & Wilson (1979) • The aim of the test is to measure food intake in a controlled environment & examine the effect of preloading on eating behaviour. • The result: • Restrained eaters consumed significantly more food than the unrestrained eaters, irrespective of preload size. • The study identified the ‘what the hell’/disinihibition as a characteristic of overeating in restrained eaters • ‘Eating more as a result of loosening restraints in response to emotional distress, intoxication or preloading’ (Herman & Polivy 1988)- Definition of dishinibition.
