Basic forms of dieting: : 

Basic forms of dieting: Restricting the amount of food consumed Refraining from eating certain types of food Avoiding eating for long periods of time Psychological reasons for dieting, success and failure in dieting

Explanations of the impact of dieting : 

Explanations of the impact of dieting Restraint theory: 89% of female UK population consciously restrain food intake at some point in their lives (Klesges et al) Herman & Mack: Restraint theory: Attempting not to eat, actually increases probability of over-eating Supported by Earle & Beales: 27 obese women, 3 groups, 7 weeks.Results showed that at both assessment intervals, women in the diet condition are more likely to over-eat compared to women in the exercise or non-treatment condition.

Explanations for the success of failure of dieting : 

Explanations for the success of failure of dieting The boundary model:Herman & Polivy: Why does dieting lead to over-eating? Biological systems: Hunger keeps intake of food above a certain minimum and satiety works to keep intake below maximum level. But, psychological factors interfere with these functions. For dieters: Longer to feel hungry and more food to satisfy them = failed diet

Slide 8: 

The role of denial in dieting: Attempting to suppress or deny a thought frequently has the opposite effect. Wegner et al: Asked Pps not to think of a white bear, but asked to ring bell if they did and allowed other PPs to think about the bear. Results: Those told not to think about bear rang bell much more often than those allowed to think about it. How does that affect diet? If you can’t have it, you want it more and are likely to binge when you allow yourself to have it.

Characteristics of diets that succeed : 

Characteristics of diets that succeed Redden: The secret is in paying attention to what we eat. He found that the more you repeat an eating experience, the less you want it. Tested by Redden “Jelly bean experiment”. The more details PPS were given about the flavour of a jelly bean, PPs wanted them less. If jelly beans were refferred to as Jelly Bean No7, people didn’t get bored with having more.

Class experiment : 

Class experiment Aim: To understand the background to teenager’s eating behaviours (media, parental modelling, culture, peers etc) and to investigate what % of boys & girls have been on a diet and to discuss with them their diet successes and failures. 4 image conscious males. 4 image conscious females. Interview about: How they learnt to eat the way they do What diets have they tried? What the aim of the diet was (image or health)? Which diet was successful and why did they think it succeeded? Why did the other diets not work? Provide a conclusion to both aims above.
