Using Hypnosis for Weight Loss
Copyright (c) 2008 Mark Albertson
The escalation of obesity rates in this country has sparked a flurry of activity among both serious researchers and charlatans to discover the perfect weight loss method. A recent study of four diets revealed that the key to weight loss success isn’t the diet, but how closely you follow it. Investigators from Tufts-New England Medical Center (Journal of the American Medical Association, January 2005) have determined in a study of four popular diets that the key to successful weight loss is not the diet itself, but actually following the diet. In this one-year study of 160 overweight adults, the researchers split people into four diet groups:
· Weight Watchers (low calorie)
· The Zone Diet (low glycemic index)
· The Ornish Diet (low fat)
· The Atkins Diet (low carb)
The conclusion of the investigation was that all of these diets worked when the participants in the study followed them. The problem is that less than one in four were able to stay on their given diet for just this one year.
It should be noted that the hardest diet to follow was Atkins, followed by the Ornish Diet, but according to the authors of the study, “no single diet produced satisfactory adherence rates.” Hypnosis has been recognized as a both a method for helping people to adhere to their diets, and for re-training the mind to “think” like a lean person, in order to be able to give up dieting completely and to develop healthy eating habits that parallel the eating habits of lean people.
That being said, wild and exaggerated claims abound regarding hypnosis as it one of the more appealing methods dangled before the eyes of those who are hungry for a seemingly easy solution to a complex problem.
A careful review of the scientific literatures exposes many of the claims about weight loss through hypnosis on the internet as overly optimistic at best and openly fraudulent at worst.
Considerable controversy swirls around the mechanisms by which hypnosis actually contributes to weight loss. Leon (1976) suggested that hypnosis can help obese people team new healthier eating patterns and retain them. One author remarked that the hypnotic state is characterized by heightened concentration, suggestibility, and relaxation (Mott, 1982). Certain individuals are thought to be capable of achieving this state more readily than others. A so-called hypnotic “induction” whereby a hypnotist using certain procedures to bring an individual into the hypnotic state is not a prerequisite for achieving the state (Mott, 1982). Hypnosis, contrary to the claims of some intemet advertisers cannot magically reprogram people’s minds. In short, methods of hypnosis run the gamut from simple relaxation techniques to formal inductions administered by hypnotists, but should not be considered supernatural in its effects.
Studies showing weight loss as a result of hypnosis alone are few in number and suffer from methodological problems. Andersen (1985) reported that following 8 weekly treatment sessions and 12 weeks of practicing self-hypnosis subjects lost an average of 20.2 pounds. Cochrane and Friesen (1986) concluded that moderate weight loss was obtained by subjects using hypnosis. The experimental group, lost more weight than the controls and maintained the weight loss at a six month follow-up.
Mott (1982) stated that “although hypnosis is sometimes referred to as a method of treatment, it is more accurate to regard hypnosis as a facilitator of a number of different treatment methods.” The study concludes that the use of hypnosis for a moderate weight loss is effective using hypnotherapy. Hypnosis Plus Behavioral Weight Management A number of studies indicate that hypnosis combined with a behavioral weight management program contributes significantly to weight loss. Bolocofsky, Spinler, and Coulthard-Morris (1985) revealed that the addition of hypnosis to a behavioral program designed to alter eating patterns increased the amount of weight loss at 8-month and 2year follow-ups. Both the behavioral and hypnosis programs were tailored to each subject individually in the study. Bolocofsky et al. (1984) acknowledged that “the less a person weighed at the start of the program the more likely he was to lose weight and maintain the reduction”. Hypnosis combined with behavioral weight management seems to be more effective for small amounts of weight loss. Another study of 45 females found that supplementing a basic self-management program with hypnosis resulted in a slightly greater amount of weight loss at a 3-month follow-up (Barabasz and Spiegel, 1989). The group for which individualized hypnotic suggestions were developed lost more weight than those exposed only to a group procedure. Kirsch (1996) noted a weight loss of 6.00 pounds without hypnosis and 11.83 pounds with hypnosis based on a meta-analysis of six studies. Allison and Faith (1996), however, disagreed and maintained that hypnosis only enhances cognitive-behavioral psychotherapy slightly if at all. Long-term individualized hypnosis combined with a behavioral weight management program appears to contribute to modest weight loss and helps maintain it.
Hypnosis operates mainly as a way to increase participants’ attention to suggestions of behavioral programs as well as to reinforce their weight loss. Studies using behavioral treatments successfully “typically have developed incentive systems to bridge the gap between the short-term -reinforcers provided during treatment and long-term goal of weight reduction” (Bolocofsky et al., 1985). Hypnosis can fulfill this role by stepping in as a psychological reinforcer. Hypnosis may assist subjects in learning positive eating behaviors and creating healthy long-term patterns of food intake. Subjects are then more likely to incorporate the rules of a particular program into their behavioral regimes (Bolocofsky, 1985). Kroger (1970) points out the similarities between hypnosis and behavioral treatments which share an emphasis on visualization and imagination. The literature suggests that hypnosis is an ideal addition to behavioral weight management programs which tend to need supplementation to achieve long-term results.
The Hodgepodge Problem in Weight Loss Studies The use of subjects of varying ages and backgrounds represents one challenge that plagues studies of hypnosis as a useful treatment for weight loss. Andersen (1985) utilized subjects ranging in age from 21-56 years, a considerable spread. Subjects in another study ranged in age from 17 to 67 resulting in considerable potential differences between the control group and the hypnosis group (Bolocofsky et al., 1985). The fact that subjects were not matched with regard to age could exaggerate results of weight loss as a result of hypnosis that may more accurately be attributed to age differences. McCabe, Jupp, and Collins (I985) suggested a tendency for younger women to drop out of weight loss programs relative to older women leading to a possible masking of potential effects of age. Bolocofsky et al. (1984) indicated that successful hypnotic weight loss participants were higher in self-control, weighed less at the start of the study, married, and more expressive. A wide variety of factors influence whether a given subject will lose weight through a hypnotic weight loss program. Anderson (1985) cites the absence of matched subjects as a weakness in her experiment. More studies with subjects closely matched on various characteristics should be conducted to substantiate claims about the effectiveness of hypnosis for weight loss when combined with a behavioral program.
Most studies require weekly consultation with a hypnotist for 8 weeks or more in addition to self-hypnosis (Bolocofsky et al., 1984; Bolocofsky et al., 1985, Andersen, 1985; Cochrane & Friesen, 1986; McCabe et al., 1985). Internet advertisers who claim weight loss will occur following a single hypnotic session, especially a group hypnotic session, are frauds selling dreams to desperate customers. Allison and Faith (1996) underscore that “there is currently no panacea for the treatment of obesity and hypnosis is no exception”. Treatment using hypnosis then is not a quick and easy way out of weight troubles. In order to achieve any benefits from its use, hypnosis must be practiced on a regular basis for a significant period of time.
Conclusions and Limitations
Hypnosis has been shown to be an effective treatment for low to moderate amounts of weight loss. One qualification of this statement is that the hypnotic program should be tailored to each individual. Hypnosis is a process by which an individual enters a state of relaxation and heightened suggestibility, Transformation of the brain through some mysterious process defines only the hypnosis of pseudoscientists. Quick-fix hypnosis is probably much less effective than an 8 week program using both in-session hypnosis, at-home self-hypnosis, and behavioral weight management. The only people who claim hypnosis is easy, simple, and quick are those trying to sell people on their program. The largest obstacle in weight loss is its long-term retention, but follow-ups of hypnosis as a weight loss treatment have been conducted at the longest after two years. Weight loss tapes lack scientific evidence to support their success and should be purchased with this knowledge in mind. Weight loss through hypnosis has been largely ignored by scientists and more studies with control groups and large subject pools are required to understand its action and import.
