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.
