Investigated the effects of hypnosis in weight loss for 60 females, at least 20% overweight. 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 17lbs vs. 0.5 lbs on follow-up. Cochrane, Gordon; Friesen, J. (1986). Hypnotherapy in weight loss treatment. Journal of Consulting and Clinical Psychology, 54, 489-492.
109 people completed a behavioral treatment for weight management either with or without the addition of hypnosis. At the end of the 9-week program, both interventions resulted in
significant weight reduction. At 8-month and 2-year follow-ups, the hypnosis subjects were found to have continued to lose significant weight, while those in the behavioral-treatment-only group showed little further change. Journal of Consulting and Clinical Psychology (1985)
Researchers analyzed 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 the non-hypnosis, and maintained the weight loss two years after treatment ended.

Study of the effect of adding hypnosis to cognitive- behavioral treatments for weight reduction, additional data were obtained from authors of 2 studies. Analyses indicated that the benefits of hypnosis increased substantially over time. Kirsch, Irving (1996). Hypnotic enhancement of cognitive-behavioral weight loss treatments–Another meta-reanalysis.

Two studies compared overweight smoking and non-smoking adult women in an hypnosis-based, weight-loss program. Both achieved significant weight losses and decreases in Body Mass Index. Follow-up study replicated significant weight losses and declines in Body Mass Index. The overt aversion and hypnosis program yielded significantly lower post-treatment weights and a greater average number of pounds lost.

… An analysis of five weight loss studies reported in the Journal of Consulting and Clinical Psychology in 1996 showed that the ” … weight loss reported in the five studies indicates that hypnosis can more than double the effects” of traditional weight loss approaches. University of Connecticut

Research into cognitive-behavioral weight loss treatments established that weight loss is greater where hypnosis is utilized. It was also established that the benefits of hypnosis increase over time. Journal of Consulting and Clinical Psychology (1996)
