Eating Behaviour- Success and Failure Of Dieting Flashcards
What is the role of life milestones on successful dieting
Eg divorce illness
Ogden and Hill interviewed successful dieters and found those who lost weight and maintained it were influenced by a major life milestone
What forms of social support may influence a successful diet
Self help groups eg weight watches
Role models eg husband or wife
Vicarious reinforcement eg celebs
Social identity eg I am a dieter
What is the restraint theory and the boundary model
Attempting to eat less can have opposite effect
Developed into boundary model- non dieters food consumption is controlled by bodies and biology
What is a body weight set point
Explanation suggests we have a BWSP depending on how much body fat we have
The mechanisms in our body do not allow our weight to fluctuate much from this point
NOTE- whether we eat or not depends on biological processes
What did Herman and Polivy suggest
Dieters have a larger range between hunger and satiety
Dieters require more food to reach satiety
What are biological and cognitive boundaries
Biological boundaries are set by hunger and satiety
Cognitive boundaries are what someone believes they should eat, usually lower than required to be full
Dieters have both biological and cognitive boundaries
If dieter exceeds cognitive boundary the what he hell effect takes over
This leads to weight gain not loss!!!
Who are the researchers for success and failure of dieting
Herman and Mack
Wardle and Beale
Lowe
What did Herman and Mack do
45 female students
3 conditions: no preload; 1 milkshake preload; 2 milkshake preload
Asked to rate quality of milkshake
Given 3 tubs of ice cream and asked to eat as much in 10 mins
Given questionnaire on eating habits
Non dieters ate less in 2 milkshake conditions
Dieters in preload ate more ice cream- exceeded cognitive boundary and experienced what the hell effect
What did Wardle and Beale do
27 women
Diet group; exercise group; control group
7 weeks
Food intake was assessed under lab condition
Those in diet group ate more suggesting dieting can encourage over eating
What did Lowe do
71.6% of weight watchers maintained body weight loss of 5%
Suggesting social support is significant
Evaluation of success and failure of dieting
Gender issues- research based on females
Practical applications- weight watchers endorsed by NHS
Restraint theory cannot explain anorexia
Supporting research
Methodological issues- restraint scale or 3 question eating questionnaire
