Objective: This study aimed to investigate effects of hypnotherapy on weight loss and thus on leptin, adiponectin (ADP), and irisin levels in obese patients who presented to the psychiatry outpatient clinic to participate in hypnotherapy sessions to develop a healthy and balanced diet. Methods: The study sample included 32 individuals with a body mass index (BMI) of ≥30 and who completed the 10-week hypnotherapy. First, the Personal Information Form was handed out to the participants and then each participant's weight (in the morning on an empty stomach) and height were measured and BMI was determined. Five-milliliter blood samples were drawn before the first session, and then irisin, leptin, and ADP levels were measured using the enzyme-linked immunosorbent assay method. Then, they participated in hypnotherapy sessions once a week for 10 weeks. At the end of the 10-week hypnotherapy, 5 mL of blood was taken again and the aforementioned biochemical analyses were performed. BMIs were measured again. Results: The mean BMI values of the patients were 33.43 ± 5.28 and 31.45 ± 4.98 at the beginning and end of the hypnotherapy sessions, respectively. Serum leptin, ADP, and irisin levels, which were 9.48 ± 5.48, 6.73 ± 3.27, and 1.43 ± 1.14, respectively, at the beginning of the hypnotherapy sessions, were 6.47 ± 2.69, 7.68 ± 3.34, and 1.53 ± 1.21, respectively, at the end of the hypnotherapy sessions. The results showed that BMI and serum leptin levels decreased significantly after the hypnotherapy sessions, whereas serum ADP and irisin levels increased significantly. Conclusions: This study indicates that hypnotherapy in obesity treatment leads to weight loss in obese patients and thus to considerable changes in leptin, ADP, and irisin levels. Hypnotherapy is easy to apply, cheap, and effective; has no potential for side effects; and can be applied both alone and in combination with other treatments. However, to confirm its effects, further studies should be conducted on this issue.
