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.
