  • Explanations For The Success And Failure Of Dieting
    • Spiral Model
      • Dieting often begins in adolescence when individuals experience body dissatisfaction
        • Begins with depression e.g. low self esteem - more motivation to lose weight
        • Dieters experience short term success but ultimate failure
        • Blames failure on personal deficiency - they didn't try hard enough
      • Downward spiral caused due to failure
        • Push themselves to lose weight by eating even less rather than changing their strategy
        • Experience stress and distress - more vulnerable to disinhibited eating
        • Metabolic changes in the body make weight loss more difficult to achieve
          • Ghrelin increases
          • Leptin decreases
        • Depression increases over time as failures consist
    • Ironic Processes
      • Wegner discovered that asking people to not think about something almost always made them think about
        • Paradoxical outcome of trying to suppress a thought is to make it more likely
        • Dieters more likely to think about foods because they're trying not to
          • Leads to disinhibition
      • Distractions (e.g. reading) means the dieter has less cognitive processing to think about food
        • Have to spend all their time occupied to stop thinking about food
    • Restraint
      • Make conscious effort to restrain eating
        • Under cognitive control
          • Food seen through cognitive distortions
      • Vulnerable to internal and external cues
      • Become disinhibited and binge eat
        • Lose no more weight than those who weren't restricting their food
    • Boundary Model
      • Don't regulate eating based on hunger and satiety
        • Limit themselves on how much food they think they should eat
          • If they eat passed this point they will eat until they are full
            • "Why not I've already started"
