Definition: "successful long term weight loss maintenance, involving the intentional loss of at least 10% of initial body weight and keeping it off for at least one year."

Majority of dieters are women of whom 87% diet at some time.

Restraint Theory

Research has shown that as many as 89% of the female population in the UK consciously restrain food intake at some point in their lives/ This theory explains the consequences associated with the cognitive restriction of food intake.

Wardle & Beales 1988: Randomly assigned 27 obese women to either a diet group. an exercise group or a non treatment group for 7 weeks. At weeks 4 and 6 all p's were assessed under lab conditions. results show that women in the diet group ate more than the exercise and non treatment groups.

Herman & Mack suggest that attempting not to eat increases the probability of over eating.

Role Of Denial

Research has shown that attempting to supress or deny a thought frequently has the opposite effect.

Wegner et al: demonstrated this effect by asking p's not to think about a white bear, but to ring a bell if they did. The other group was asked to think about the bear and also ring the bell when they did. They found that the group who were asked not to think about the bear rang the bell more times than the other group.
