Effects of Self-Conditioning Techniques (Self-Hypnosis) in Promoting Weight Loss in Patients with Severe Obesity: A Randomized Controlled Trial

Mindful Self-Hypnosis Combined with Resistance Training to Reduce Perceived Stress and Improve Other Psychological Factors in Female College Students

Perceived stress is a significant problem among female college students that can impact psychological distress, sleep, and overall well-being. Mindful self-hypnosis (MSH) and resistance training (RT) have both been shown to reduce perceived stress. The rationale for the present study was to investigate whether MSH combined with RT could be more effective at reducing perceived stress as measured by the Perceived Stress Scale than RT alone due to synergistic effects achieved by combining the interventions. Forty-four female college students were randomized to one of the three groups: MSH+RT, RT only, or a wait-list control (WLC). Results indicated that, compared to RT only, the addition of MSH led to pronounced improvements in perceived stress which was significantly greater than WLC. Also, MSH+RT resulted in significant increases in mindfulness, sleep, strength, and well-being in comparison to WLC. MSH+RT was shown to be feasible with highly satisfactory participant ratings. Future research should examine the MSH+RT intervention with a larger population and with older women who are more at risk for stress and declining strength.

A Qualitative Exploration of Weight Loss Experiences through Hypnotherapy

Hypnotherapy has been gaining recognition as an alternative treatment for excess weight problems. This qualitative study aims to explore individuals' experiences of losing weight through hypnotherapy and their perceived barriers and facilitators for healthy lifestyle changes. Semistructured interviews were conducted with 15 participants (11 women and 4 men; mean age of 23 years) who recorded having lost ≥5% weight after undergoing 3 hypnotherapy sessions previously at a public university in Terengganu, Malaysia. Each interview was audiotaped, transcribed, and analyzed using thematic analysis. The themes that emerged were the usefulness of hypnotherapy, barriers, and facilitators of healthy lifestyle changes. All participants contended that hypnotherapy played a role in their weight-loss journey through increased mindful eating and enhanced motivation to make lifestyle modifications. Barriers to healthy lifestyle changes included high costs of healthy foods and lack of support for healthy food sources in social and family settings. Hypnotherapy is essential as an adjunct tool in assisting weight loss. However, additional efforts are needed to improve support in the weight management journey.

Psychosocial effects of hypnosis in patients with obesity: a pilot randomized controlled trial

The usefulness of hypnosis in patients with obesity needs to be better understood in terms of various outcomes, in addition to weight loss. The aim of this research was to investigate the effects of hypnosis and self-hypnosis in combination with nutrition education for patients with obesity, as opposed to nutrition education alone, on the secondary outcomes of quality of life (QoL), coping strategies, and self-esteem within a randomized controlled trial (RCT). Eighty-two participants were included in this study (84.3% were women), with 41 in each group. Further, 70 participants had completed treatment. The intervention consisted of eight group sessions (about one every two weeks). Participants completed self-reported questionnaires assessing their QoL, coping strategies, and self-esteem (SF-36, CISS, SEI) before and after the intervention. Non-parametric analyses were performed. Both groups had comparable characteristics at inclusion (sociodemographic information, clinical information, and scores for the self-reported scales). At eight months (i.e. two months after intervention completion), patients from the hypnosis group used more task-oriented coping (p < .001), less emotion-oriented coping (p < .01) and distraction (p < .05), and had more energy/less fatigue (p < .001) compared to the group who did not undergo hypnosis. Other improvements were observed in the hypnosis group, but there were no significant differences compared with the non-hypnosis group in terms of QoL dimensions and general self-esteem. In conclusion, hypnosis and self-hypnosis in combination with nutrition education seem to be promising interventions to help patients deal with obesity, especially by improving their coping strategies.

The use of audio self-hypnosis to promote weight loss using the transtheoretical model of change: a randomized clinical pilot trial

Background

Few studies suggest the use of hypnosis in weight loss may be beneficial, especially when in conjunction with other lifestyle modifications or cognitive behavioral therapy. The primary aim of this study was to determine the ability of self-hypnosis audiotape to promote weight loss by measuring its effects on the Transtheoretical Model (TTM) of change stages and processes.

Methods

This study is a 3-week randomized double-blinded parallel controlled trial among adults who have overweight or obesity. The intervention group listened to a self-hypnosis audio file while the control group listened to a placebo audio file.

Results

Forty-six participants completed the 3-week follow-up visit. There was no association between progression across stages of change and self-hypnosis (X2(2, 46) = 1.909, p-value = 0.580). Gender, baseline BMD, and baseline S-weight had no effect on the association between stage change progression and self-hypnosis. The mean difference in weight at 3 weeks was -0.63 ± 0.43 kg in the hypnosis group and 0.0 ± 1.5 kg in the control group, independent t-test, p = 0.148.

Conclusion

Self-hypnosis was not associated with a progression in the TTM's stages of change or with weight loss after 3 weeks. As this pilot study was underpowered, further research with larger sample size and an examination of the effect of various self-hypnosis content and duration is recommended.

Hypnosis reduces food impulsivity in patients with obesity and high levels of disinhibition: HYPNODIET randomized controlled clinical trial

BACKGROUND

The obesogenic environment of Western countries raises questions about its current management. Some clinical studies have explored hypnosis, although the current state of knowledge does not lead to definitive conclusions about its efficacy.

OBJECTIVES

We assessed the impact of Ericksonian hypnosis and self-hypnosis on disinhibition of eating in adults with obesity and high food impulsivity levels, compared with standard nutritional education.

METHODS

From September 2014 to July 2015, adults with BMI (in kg/m2) of 30-40 and a high disinhibition score [>8 on the Three Factor Eating Questionnaire (TFEQ-51)] were included in a randomized controlled trial. The control and hypnosis groups received the same standard nutrition education in 8 workshops. In the hypnosis group, subjects had 8 sessions of hypnosis combined with training in self-hypnosis. Disinhibition (primary outcome) and other scores from the TFEQ-51 as well as anthropometric, food intake, cardiometabolic, and physical activity variables were collected at inclusion and at 8 mo.

RESULTS

Of 82 randomly assigned adults, 70 participated in all sessions; 80 participated in ≥1 session and were included in the main analysis (hypnosis group, n = 41; control group, n = 39). After 8 mo of follow-up, disinhibition scores adjusted for baseline values were lower in the hypnosis group, with a mean between-group difference of 4.2 (95% CI: 2.8, 5.5; P < 0.001); 67.7% of adults in the hypnosis group had normalized their disinhibition (compared with 11.1% in control; P < 0.0001). Differences for weight (1.8 kg; 95% CI: -0.1, 3.7 kg; P = 0.052), BMI (0.8; 95% CI: 0.1, 1.4; P = 0.028), susceptibility to hunger score (2.2; 95% CI: 1.0, 3.3; P < 0.001), and its 2 subscales also favored the hypnosis group.

CONCLUSIONS

In the management of adults with obesity and a high disinhibition score, hypnosis and self-hypnosis can significantly improve the deep mechanisms of eating behaviors and seem to have a beneficial effect on weight loss.This trial was registered at clinicaltrials.gov as NCT02292108.

Does hypnosis result in greater weight loss compared to conventional approach?

Hypnosis has been increasingly used in recent years as an alternative treatment to maintain well-being. Yet, limited evidence is available regarding its role in weight management, especially in Malaysia. Hence, this quasi-experimental study was conducted to evaluate the effectiveness of hypnosis on weight loss and body composition (body mass index, waist circumference and body fat percentage) among staff and students of a public university in Terengganu, Malaysia. Participants with body mass index (BMI) ≥ 25.0 kg/m² were randomly assigned to either intervention group (IG = 53) or control group (CG = 54), for 12 weeks. All participants received health education (diet + exercise + behavioral recommendations) with those in IG had additional three hypnotherapy sessions, once a month. Body weight was measured at week 1, 7, and 12 while body compositions were measured at weeks 1 and 12. Descriptive, univariate, and repeated-measures analysis of covariance (ANCOVA) were utilized. A total of 104 participants completed the trial (mean age = 26.28 ± 8.01; female = 82.2%; BMI = 31.39 ± 4.89). A significant weight loss was observed in the intervention (-4.61%) and control (-3.04%) groups (mean difference = -1.57; 95%CI: -2.59, -0.54; p = .003) after 12 weeks. Participants that frequently practiced self-hypnosis lost more weight (-6.27%; t(50) = -5.331, p < .001). Body fat percentage and waist circumference did not significantly change from baseline in both groups. Essentially, the positive outcomes indicated the promising potential of hypnosis as an alternative tool in facilitating weight loss efforts for those in need.

Complementary and Alternative Therapies for Weight Loss: A Narrative Review

Despite various strategies, overweight and obesity problems are still increasingly prevalent worldwide with serious health outcomes. Consequently, the continuous demand for more effective, safe and acceptable therapies for reducing body weight is also escalating—including complementary and alternative therapies (CATs). The aim of this review is to provide a summary of the most commonly- and recently-used CATs, with evaluation of their safety and efficacy for weight loss. Electronic scientific databases such as Scopus, PubMed and EBSCO Host were explored for articles that reported CATs for overweight and obesity treatment from 2015 to December 2019. Only systematic reviews, meta-analysis and randomized controlled trials (RCTs) published in English were included. Studies whereby CATs were not utilized for reducing body weight were excluded. Eight systematic reviews and meta-analyses and 11 additional RCTs with 765 participants (50.2% overweight and 49.8% obese) related to hypnotherapy, acupuncture and dietary supplements met the inclusion criteria. Their results suggested that spirulina, chitosan, probiotic, EPA + DHA, vitamin D, fiber, and herbal extract supplementation may all provide small reductions in body weight (ranging from 1-10 kg). Interestingly, hypnotherapy and acupuncture reported significantly greater reduction in body weight compared with placebo (p < 0.001 and p < 0.0001, respectively). Nonetheless, the evidence is still relatively limited and not encouraging to provide a definitive conclusion due to the methodological shortcomings and the presence of adverse events in chitosan and fiber supplementation. Hence, studies of this nature need to be further replicated and improved to corroborate the efficacy and safety of the CATs to combat weight issues.

The Use of Self-Help Strategies in Obesity Treatment. A Narrative Review Focused on Hypnosis and Mindfulness

PURPOSE OF REVIEW

The aim of this narrative review was to summarize the evidence evaluating the possibilities and limitations of self-hypnosis and mindfulness strategies in the treatment of obesity.

RECENT FINDINGS

Psychological factors, such as mood disorders and stress, can affect eating behaviors and deeply influence weight gain. Psychological approaches to weight management could increase the motivation and self-control of the patients with obesity, limiting their impulsiveness and inappropriate use of food. The cognitive-behavioral therapy (CBT) represents the cornerstone of obesity treatment, but complementary and self-directed psychological interventions, such as hypnosis and mindfulness, could represent additional strategies to increase the effectiveness of weight loss programs, by improving dysfunctional eating behaviors, self-motivation, and stimulus control. Both hypnosis and mindfulness provide a promising therapeutic option by improving weight loss, food awareness, self-acceptance of body image, and limiting food cravings and emotional eating. Greater effectiveness occurs when hypnosis and mindfulness are associated with other psychological therapies in addition to diet and physical activity. Additional research is needed to determine whether these strategies are effective in the long term and whether they can be routinely introduced into the clinical practice.

The feasibility and acceptability of hypnotherapy among overweight and obese individuals in a Malaysia's public university

OBJECTIVES

The global epidemic of overweight and obesity presents a major challenge in the health status of the society. Their prevalence is at an alarming rate worldwide due to poor compliance with conventional treatment and high rates of relapse, thus increasing demand for an effective and safe alternative approach such as hypnotherapy. This study aimed to evaluate the feasibility and acceptability of hypnotherapy for weight loss and to compare these among selected socio-demographics.

METHODS

A cross-sectional study was conducted among 30 students and staff of a public university in Terengganu, Malaysia using convenience sampling. Data analysis was carried out using SPSS 23.0.

RESULTS

Among the respondents (age = 26.17 ± 8.23 years; female = 66.7%; students = 63.3%), 40.0% were overweight and 60.0% were obese. Results indicated excellent feasibility as determined by participants' satisfaction towards the clarity of hypnotherapist's voice (93.3%), the suitability of content (86.7%) and time spent for the session (90.0%). Good overall acceptability (>60.0%) was also reported regarding hypnotherapist professionalism, the environment and perceived usefulness of hypnotherapy. Obese individuals were significantly more satisfied towards the hypnotherapist environment than overweight respondents (p=0.015). Additionally, no adverse effects were reported after the intervention.

CONCLUSIONS

This evidence signalled that hypnotherapy is a promising alternative tool in assisting overweight and obese individuals to lose weight. Extensive research is needed to substantiate its role in weight management programs for its full benefits.

Hypnotherapy for overweight and obese patients: A narrative review

Obesity and overweight problems are serious global health issues today and despite many efforts, the prevalence has continued to rise for decades. Interestingly, hypnotherapy has been gaining recognition as an effective treatment for obesity and overweight problems. This review compiles contemporary scientific research on the effectiveness of hypnotherapy for weight reduction. Scopus, PubMed and EBSCO Host databases were applied in the study. The search identified 119 articles, of which seven met the inclusion criteria. A total of 539 respondents (82.7% women and 17.3% men) between the ages of 17 and 67 years were represented in the seven studies. Most studies incorporated lifestyle changes, such as changes of dietary habit and behavioral recommendations in the hypnotic procedure. Their results suggested that the use of hypnotherapy not only promoted weight reduction during the treatment period but also after treatment cessation, and in some cases, one to ten kilograms were lost during follow-up periods. In addition, one study even showed increased physical activity among the hypnotised individuals. This use of hypnotherapy also improved respondents' eating behavior and quality of life. However, a definitive conclusion could not be drawn due to several methodological flaws and the limited number of published studies in this area. Therefore, further well-designed studies are needed to substantiate the effectiveness of hypnotherapy for this modern-day health problem.

Acute assessment of subjective appetite and implicated hormones after a hypnosis-induced hallucinated meal: a randomized cross-over pilot trial

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.

The Effectiveness of Group-based Cognitive Hypnotherapy on the Psychological Well-being of Patients with Multiple Sclerosis: A Randomized Clinical Trial

Multiple sclerosis is a chronic, demyelinating disease of the central nervous system mainly affecting young adults. In addition to physical problems, the patients suffer from many psychological problems affecting their psychological well-being. The aim of the present study was to determine the effectiveness of group-based cognitive hypnotherapy on the psychological well-being of patients suffering from multiple sclerosis. This study was designed as a clinical trial with a pretest-posttest control group. From 60 patients diagnosed with multiple sclerosis referred to Beheshti hospital in Yasuj, Iran, 45 patients who met the inclusion criteria were selected by the convenience sampling method. The patients were randomly assigned to intervention (23 individuals) and control (22 individuals) groups through stratified random allocation. After completing the Ryff Scales of Psychological Well-Being, the intervention group attended eight sessions of group-based cognitive hypnotherapy on a weekly basis. The control group did not attend any intervention sessions. At the end of the eight intervention sessions, both groups completed the Ryff's Scale of Psychological Well-being again. The collected data were analyzed using the SPSS software (Version 23). Analysis of Covariance (ANCOVA) and two-way Analysis of variance (ANOVA) tests were used in order to compare the groups. The results indicated that cognitive hypnotherapy had a significant effect on the total score of psychological well-being (F (45, 1) = 6.07, p = .018, η2 = 0.12) and the dimension of environmental mastery (p < .05). Therefore, it is recommended to use hypnotherapy to promote the psychological well-being of patients suffering from multiple sclerosis.
