Here is the last of three studies investigating the effectiveness of hypnotherapy in assisting with weight loss.
In this meta-analysis, (which is when researchers correlate the results of multiple studies), the results of the two studies in my last two posts and other studies were
In the studies of hypnosis versus no hypnosis the average short-term weight loss was 6 pounds for those not using hypnosis and 11.83 pounds with hypnosis. Even more importantly, over the long term the average weight loss without hypnosis remained at 6 pounds, but with hypnosis it jumped to 14.88 pounds, indicating again that the effects of hypnosis seem to continue over time.
What is impressive about these results is that doing hypnosis under controlled conditions is extremely difficult, and to have the research indicate that people are losing anywhere from about 2 to on average 16 1/2 times more weight under hypnosis than when they do not use it, clearly indicates that hypnosis is a highly effective tool in our weight management toolbox.
