Research: Weight loss hypnosis has legs

Hypnosis Subjects Lost More Weight Than 90% of Others and Kept it Off Reviewed 18 studies comparing a cognitive behavioral therapy such as relaxation training, guided imagery, self monitoring, or goal setting with the same therapy supplemented by hypnosis. Those who received the hypnosis lost more weight than 90 percent of those not receiving hypnosis and maintained the weight loss two years after treatment ended. J Consult Clin Psychol. 1996;64(3):513-516.

Hypnosis Over 30 Times as Effective for Weight Loss Treatment included group hypnosis with metaphors for ego-strengthening, decision making and motivation, ideomotor exploration in individual hypnosis, and group hypnosis with maintenance suggestions. Hypnosis was more effective than a control group: an average of 17 lbs lost by the hypnosis group vs. an average of .5 lbs  lost by the control group  Consulting and Clinical Psychology, 54, 489-492.

Two Years Later: Hypnosis Subjects Continued To Lose Significant Weight 109 people had treatment for weight with or without hypnosis. After 9-weeks both groups lost significant weight. At 8-month and 2-year follow-ups, the hypnosis subjects were found to have continued to lose significant weight, while those in other group showed little further change.
