- Psychological explanations for obesity
- Restraint theory
- obesity results from placing unsustainable limits on food intake
- occurring through attempting to lose weight by having strict intake targets by reduced eating
- self-imposed target often unrealistic + attempting to diet in this way, lowers mood + increases hunger + motivation to eat more.
- type of people likely to attempt restrained eating those w/ less self-control, more likely to display disinhibited eating - more vulnerable to becoming obese.
- Restraint theory evaluation
- Herman + Polivy - dieters reported couldn't be bothered to keep dieting, too much effort
- suggests cognitive shift in thinking - breakdown of self-control in line w/ boundary model
- Disinhibition major factor in weight gain
- obesity b/c oh high daily number eating opps found in Western cultures.
- Lowe + Kral - among restrained eaters, over-representation of people w/ tendency for lack of self-control + disinhibited eating.

- Herman + Polivy - dieters reported couldn't be bothered to keep dieting, too much effort
- Disinhibition
- overeating through the loss of restraint over food intake
- Occurs when have opp to consume desirable foods + under emotional distress
- anxiety-prone individuals, w/ poor impersonal attachments - rely more on external factors eg food, for emotional control.
- tendency to seek emotional comfort through overeating
- Boundary Model
- obesity results from conflict between physiological and cognitive limits on food intake
- distance between levels set by psych factors, w/ dieters having large range between hunger + satiety level as takes longer to feel hungry + need more food to reach satiety
- physiological set point boundary overrides self-imposed cognitive boundary - overeating w/ such individuals being at increased risk of being obese.
