Summary
Researchers had debated whether adding hypnosis to cognitive-behavioural weight-loss programmes makes a difference. One reanalysis (Allison & Faith, 1996) concluded the extra benefit was small.
In this reanalysis, Irving Kirsch looked at the same trials and found that people who received hypnosis lost roughly twice as much weight by the end of treatment — and the gap kept widening at follow-up, while those without hypnosis tended to plateau. The size of the benefit is still debated, but both analyses found adding hypnosis helped.
Key finding
Adding hypnosis to weight-loss treatment led to more weight loss, with the advantage growing over time.
Why this matters
Lasting change with food rarely comes from willpower alone. When the subconscious is on board, new habits tend to stick — and keep building.
Research is summarised in plain language for a general audience. Hypnotherapy and energy healing are complementary approaches and are not a substitute for medical or psychiatric care.
