Compulsive Eating (4)
Researchers from Plymouth University in the UK investigated whether brief guided imagery and body scanning exercises could reduce food cravings.
Elaborated Intrusion (EI) Theory proposes that cravings occur when involuntary thoughts about food are elaborated with affectively-charged imagery. It has been found that craving can be weakened or interrupted by working memory tasks that block the imagery or prevent the involuntary thoughts from being elaborated in the first place.
Research has found that imagery techniques such as body scanning and guided imagery can reduce the occurrence of food thoughts.
This study tested the prediction that body scanning and guided imagery can also reduce craving.
In the past, studies of weight-control diets that are high in protein
or low in glycemic index have reached varied conclusions, probably
owing to the fact that the studies had insufficient power.
Because of this, a team of researchers enrolled overweight adults from eight European countries who had lost at least 8% of their initial body weight with a low-calorie diet. Participants were randomly assigned, in a two-by-two factorial design, to one of five diets to prevent weight regain over a 26-week period. These were: a low-protein and low-glycemic-index diet, a low-protein and high-glycemic-index diet; a high-protein and low-glycemic-index diet; a high-protein and high-glycemic-index diet; or a control diet.
Researchers from the Lancashire Care NHS Foundation Trust in Chorley, UK, investigated the efficacy of a CD-ROM offering Cognitive Behavioral self-help treatment to patients with binge eating disorder and/or bulimia nervosa, many of whom find it hard to access treatment otherwise. Rates of failure to enter treatment and to stay with treatment are extremely high for this population.
Patients referred to a catchment-based NHS outpatient eating disorders service who were assessed and had an eating disorder with a binge-eating component were offered CD-ROM based CBT (Overcoming Bulimia) whilst on the waiting list for individual CBT.
There was a therapist-led condition, where the psychologist provided psycho-educational information for the first half hour and led a group discussion for the second half hour of each session; there was a partial self-help condition, where participants viewed a 30-min psycho-educational videotape, followed by a therapist-led discussion; and finally, there was a structured self-help condition, where participants watched a psycho-educational videotape and led their own discussion.
