Here is an overview of the second of three studies I am posting that investigated the effectiveness of hypnotherapy in weight loss.
Study 2*
This study, published in the “Journal of Consulting and Clinical Psychology,” investigated the effects of hypnosis in weight loss for 60 females at least 20% overweight and not involved in other treatment. The researchers interviewed each participant this time about their family background, educational background, and their belief as to their hypnotizability.
The group was split into hypnosis and non-hypnosis groups with both groups being given weight-loss behavioural treatments and counselling. The results were very interesting. The group using hypnosis lost an average of 17 pounds at the 6-month follow up. The group that did not receive hypnosis only lost 1/2 pound. They also found that “hypnotizability” and social and educational backgrounds had nothing to do with the results.
