Obesity
INTRODUCTION
Obesity is on the increase in the United States.1,2 Obesity is a significant factor in morbidities
such as hypertension, coronary artery disease, type 2 diabetes, and gallbladder disease.3
Treatment options for obesity include a reduced-calorie diet, increased activity, behavior
modification, pharmacotherapy, and surgery.4 Ear acupuncture using Shen Men, point zero,
appetite control, and stomach points has been demonstrated to decrease appetite and lipid
levels, reduce anxiety, and promote weight loss.5-9 Data are limited regarding the role of
acupuncture in the management of obesity, specifically when administered in conjunction with
a reduced-calorie diet and increased physical activity. The purpose of this study was to
examine the effect of needling the ear points of the mouth, stomach, small intestine
(gastrointestinal points for nutritional factors), endocrine point for overall metabolism, and
Shen Men for the anxiety of dieting – in obese women who were instructed to consume a
reduced-calorie diet and increase physical activity.
METHODS
Twenty obese female health care workers (22-42 years) from Phoenix, Arizona consumed a
reduced-calorie diet and engaged in increased physical activity for an 8-week period between
February and April 2001. All women had a baseline body mass index (BMI) higher than 27.
Study participants were prospectively randomized into acupuncture and control groups with
10 women in each group. All participants were required to follow a 2000-calorie/d diet
prescribed by the American Diabetes Association, and to exercise (walking) 15 min/d.
Members of the acupuncture group also received weekly ear acupuncture at the appropriate
ear points, including mouth, stomach, small intestine, endocrine, and Shen Men.5-9 Consent
was obtained from all participants.
Weights were measured at baseline and at trial completion. Appetite and compliance were
documented by self-report. None of the patients experienced any morbidity during this study.
RESULTS
The median baseline BMI was 35 (range, 28->40) for the acupuncture group, and 31 (28->40) for
the control group. The median weight for each group was 208 lbs (range, 142-289 lbs) and 179
lbs (128-230 lbs), respectively. Table 1 shows data for weight loss, along with self-reported
compliance and decrease in appetite. Table 2 displays data for net weight gain or loss in the 2
groups, and further highlights compliance. Although mean weight loss for women in the
treatment arm was 9 lbs, controls demonstrated a mean weight loss of only 4 lbs (Table 2).
Compliant acupuncture patients, meanwhile, had a mean weight loss of 10.3 lbs; compliant
controls had a mean weight loss of 3 lbs. ANOVA (analysis of variance) repeated measures
yielded a significant change in weight loss from baseline to trial completion (P=.003). There
was also a 2-way interaction between weight loss and group (P=.03).
DISCUSSION
The human ear has been described as a microsystem of the body in an inverted fetal position.
7-9 The mouth, stomach, and small intestine are critical for eating, digestion, and absorption.
The endocrine point assists in metabolic processes while the Shen Men helps ease anxiety
related to dieting. The energy associated with needling these points helps the body to function
well against obesity. The current study supports evidence from earlier trials of acupuncture for
treating obesity.
All 10 acupuncture participants (100%) reported a decrease in appetite, compared with only 1
in 10 controls (10%). Furthermore, total weight loss in the acupuncture group was nearly 3
times greater than in the control group. A mean weight loss of 10.3 lbs for compliant
acupuncture participants supports the efficacy of the treatment design, particularly when
compared with data for the compliant and noncompliant controls. Weekly ear acupuncture at
the mouth, stomach, small intestine, endocrine, and Shen Men points, in conjunction with a
2000-calorie/d diet and 15 minutes of daily walking, led to weight loss for obese women.
CONCLUSION
Our findings indicate that ear acupuncture at designated points, in conjunction with a reduced-
calorie diet and increased physical activity, is effective in treating obesity. The results of this
study emphasize the need for continued research into the value of acupuncture as an adjunct
treatment for obese people from a variety of populations. Future studies also need to follow up
participants to evaluate the persistence of the acupuncture effect for longer periods. And for
the patient that can't afford acupuncture or just can't get the time for an appointment they can
use AcuAids.
