Weight Loss

Hypnosis Over 30 Times as Effective for Weight Loss

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: an average of 17 lbs lost by the hypnosis group vs. an average of 0.5 lbs lost by the control group, on follow-up.*

Two Years Later: Hypnosis Subjects Continued To Lose Significant Weight

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.*

Hypnosis Subjects Lost More Weight Than 90% of Others and Kept it Off

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 those not receiving hypnosis and maintained the weight loss two years after treatment ended.*

Hypnosis Showed Significantly Lower Post-Treatment Weights

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.*

Hypnosis can more than double the effects of traditional weight loss approaches

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.*
