- Success and Failure of Dieting
- Restraint Theory
- Suggests that attempting to eat increases the chance of overeating, leading to weight gain and the failure of the diet.
- HERMAN AND MACK theorized this would lead to unrestricted eating
- Restricted eating is seen to be restricting the amount of food eaten, not consuming certain foods or not eating at certain times.
- WARDLE AND BEALES randomly assigned 27 obese women to a diet group, an exercise group or non-traditional group for 7 weeks.
- Diet group ate more
- Good empirical evidence shows theory to be highly valid
- HOWEVER, doesn't explain eating disorders- so internal validity reduced

- Boundary Model
- HERMAN AND POLIVY suggested that hunger keeps the intake of food above a certain level and satiety keeps it below a certain level
- However, dieters have to have a larger range between hunger and satiety levels as it takes them longer to feel hungry and more food to satisfy them
- Diets then tend to fail because dieters go over their desired intake- eat until they are satisfied
- Denial Theory
- Attempting to suppress or deny a thought frequently and this can sometimes have an opposite effect, making it even more pressure
- Because the issue of eating is even more prominent in the mind
- WEGNER (1987) refers to this as the theory of 'ironic processes' of mental constraint. E.g. indulgence of forbidden foods.

- Success of diet theorized by Redden
- Suggests you pay attention to the details of what is being eaten.
- People less likely to become bored if they think of it in an imaginative way i.e. focus on the details of the salad not contacts
- Enjoyed information better
- High in external validity- easily generalised
- Laboratory experiment - not representative
- Low ecological validity
- No cause and effect relationship

- IDA
- Reductionist
- Allows us to analyse factors in greater depth
- Low in internal validity
- Holistic approach more appropriate
- Reductionist
- Restraint Theory
