The scientific studies that prove hypnosis for weight loss works

Journal of Clinical Psychology, 41 (1), 35-41 109
17-67 year olds completed a behavioral treatment for weight management either with or without the addition of hypnosis. Results show that, at the end of the 9-week program, both interventions resulted in significant weight reduction. However, at 8-month and 2-year follow-ups, the hypnosis subjects showed significant additional weight loss, while those in the behavioral-treatment-only group exhibited little further change. More subjects who used hypnosis also achieved and maintained their personal weight goals.

Averaged across post-treatment and follow-up assessment periods, the mean weight loss was 6.00 lbs. (2.72 kg) without hypnosis and 11.83 lbs. (5.37 kg) with hypnosis….At the last assessment period, the mean weight loss was 6.03 lbs. (2.74 kg) without hypnosis and 14.88 lbs. (6.75 kg) with hypnosis… Correlational analyses indicated that the benefits of hypnosis increased substantially over time.

Investigated the effects of hypnosis in weight loss for 60 females at least 20% overweight and not involved in other treatment….There were two experimental groups (hypnosis with and without audiotapes) and a control group, assessed immediately after treatment and at 6-month follow-up. Ability to be hypnotised, use of audiotapes, and other variables were not predictive of weight loss. But, hypnosis was more effective than a control group- (17 pounds vs. .5 pounds on follow-up).

What experts have to say about NLP
“NLP cannot be dismissed as just another hustle. Its theoretical underpinnings represent an ambitious attempt to codify and synthesize the insights of linguistics, body language, and the study of communication systems.”
Psychology Today

“(NLP) does offer the potential for making changes without the usual agony that accompanies these phenomena. . . Thus it affords the opportunity to gain flexibility, creativity, and greater freedom of action than most of us now know.”
