Pilot Investigation of a Virtual Gastric Band Hypnotherapy Intervention

This 24-week long pilot investigation of 30 men and women with a BMI > 27kg/m2 aimed to determine whether virtual gastric band (VGB) hypnotherapy has an effect on weight loss in overweight adults, compared to relaxation hypnotherapy and a self-directed diet. Levels of weight loss and gain ranged from -17kg to +4.7kg in the VGB hypnotherapy group and -9.3kg to +7.8kg in the relaxation group. There was no significant difference between VGB hypnotherapy as a main effect on weight loss (Chi2 = 0.67, p = .41, df = 1) and there was no evidence of differential weight loss over time (Chi2 = 4.2, p = .64, df = 6). Therefore, the authors conclude that there was no significant difference between VGB hypnotherapy and the relaxation hypnotherapy.
