Abstract
The use of hypnosis can generate hallucinatory phenomena, which ranged from vivid/auditory imagery to fully developed "hallucinations" in selected people. The aim of this pilot trial was investigating the acute effects of a hypnosis-induced hallucinated breakfast (HB) compared to those of a real breakfast (RB) on subjective appetite and appetite-regulating hormones in highly hypnotizable individuals. Eight healthy post-menopausal women were recruited to consume two meals: the HB and the RB in a randomized crossover design. Participants underwent appetite sensations measurements (before meal and each 30-min until 270-min) and blood sample collection (at 0, 20, 60, 90, 180-min). A 3-day food-record was filled after each meal. The adjusted repeated measures ANCOVA did not show any meal×time interactions on subjective appetite postprandially. As expected, significantly higher glucose (p < 0.001), insulin (p < 0.001), and lower free fatty acid (p < 0.001) concentrations were found after the RB, but not following HB. Furthermore, RB significantly increased postprandial levels of glucagon-like-peptide-1 and peptide-YY at 20, 60, 90 and 180-min, whereas acylated-ghrelin and leptin levels did not differ. Postprandial neuropeptide-Y and orexin-A values significantly increased at different time-points after RB, but not following HB, while α-melanocyte-stimulating hormone levels enhanced after HB only. Energy intakes were significantly lower after HB on the test-day only (HB = 1146.6 ± 343.8 vs RB = 1634.7 ± 274.2 kcal/d; p = 0.003). Appetite sensation might be modulated by fully developed meal "hallucination" induced by hypnosis, likely affecting brain-peptides implicated in the appetite regulation. However, further studies are needed to verify these results obtained in a highly selected group of individuals. NCT03934580.

Abstract
OBJECTIVE The usefulness of the rapid-induction techniques of hypnosis as an adjunctive weight-loss treatment has not been defined. This randomized controlled trial evaluated whether self-conditioning techniques (self-hypnosis) added to lifestyle interventions contributed to weight loss (primary outcome), changes in metabolic and inflammatory variables, and quality of life (QoL) improvement (secondary outcomes) in severe obesity. METHODS Individuals (with BMI = 35-50 kg/m2 ) without organic or psychiatric comorbidity were randomly assigned to the intervention (n = 60) or control arm (n = 60). All received exercise and behavioral recommendations and individualized diets. The intervention consisted of three hypnosis sessions, during which self-hypnosis was taught to increase self-control before eating. Diet, exercise, satiety, QoL, anthropometric measurements, and blood variables were collected and measured at enrollment and at 1 year (trial end). RESULTS A similar weight loss was observed in the intervention (-6.5 kg) and control (-5.6 kg) arms (β = -0.45; 95% CI: -3.78 to 2.88; P = 0.79). However, habitual hypnosis users lost more weight (-9.6 kg; β = -10.2; 95% CI: -14.2 to -6.18; P < 0.001) and greatly reduced their caloric intake (-682.5 kcal; β = -643.6; 95% CI: -1064.0 to -223.2; P = 0.005) in linear regression models. At trial end, the intervention arm showed lower C-reactive protein values (β = -2.55; 95% CI: -3.80 to -1.31; P < 0.001), higher satiety (β = 19.2; 95% CI: 7.71-30.6; P = 0.001), and better QoL (β = 0.09; 95% CI: 0.02-0.16; P = 0.01). CONCLUSIONS Self-hypnosis was not associated with differences in weight change but was associated with improved satiety, QoL, and inflammation. Indeed, habitual hypnosis users showed a greater weight loss.

Abstract
<p><strong>Background:</strong> Obesity is a worldwide epidemic; most obese individuals who lose weight after lifestyle educative treatments, soon regain it. Our aim is to evaluate the effectiveness of a training to teach self-conditioning technique (self-hypnosis) added to standard care in determining weight loss compared with standard care in patients with obesity</p><p><strong>Methods: </strong>This randomized controlled open trial will recruit 120 obese patients (BMI 35-50 Kg/m<sup>2</sup>), aged 20-70 years. The control group will receive a traditional approach: diet + exercise + behavioral recommendations. The experimental group will receive self-conditioning techniques + traditional approach.</p><p>Three individual sessions of hypnosis with rapid-induction techniques will be administered by trained personnel. All the participants of both groups will be assessed at three, six, nine and twelve months after randomization. The primary outcome is weight loss difference between groups at 12 months after randomization; secondary outcomes are changes in adherence to dietetic and exercise recommendations, appetite and satisfaction/well-being, waist circumference and body fat, blood pressure and blood metabolic and inflammatory variables.</p><p><strong>Conclusions: </strong>The results of this trial will assess whether a self-conditioning approach, based on self-hypnosis, is able to help participants to modulate unhealthy patterns of eating and sustain weight loss in the long term.<strong></strong></p>
