Ear acupuncture using metal beads can help reduce weight, body mass index (BMI), and body fat in combination with a restricted diet, according to new research being presented at this year's European Congress on Obesity (ECO) in Dublin, Ireland (17-20 May).
The study by Dr Takahiro Fujimoto from Clinic F, Tokyo, Japan and colleagues suggests that food cravings can be controlled using the simpler method of acupuncture stimulation with beads rather than the traditional use of intradermal needles, which requires expert acupuncturists.
"Since these tiny metal beads are attached to six points on the outer ear that stimulate nerves and organs which regulate appetite, satiety and hunger, this type of acupuncture does not require complex knowledge or skill," explains Dr Fujimoto. "In Japan, this method to aid weight loss has been used for over 30 years."
In traditional Chinese medicine, acupuncture is based on the understanding that your health depends on the flow of qi (energy) in your body.
This energy travels along invisible pathways, known as meridians, that are found throughout your body, including your ears. A blocked or disrupted flow of qi can have a negative effect on your physical and mental health.
Auricular (ear) acupuncture therapy is based on the theory that the outer ear represents all parts of the body. Thin needles or beads are placed on certain points, usually along meridian lines, to restore the flow of qi by resolving any blockages or disruption and may help with a variety of health conditions.
The approach has been used to treat drug addiction and to help people give up smoking and lose weight.
While the mechanism is unclear, studies suggests that ear acupuncture may help to regulate the endocrine system, modulate metabolism, promote digestion, and lessen oxidative stress [1].
This new study builds on previous research in Japanese women with overweight or obesity which found that those treated with ear acupuncture with beads lost significantly more weight than those who were untreated, and this weight loss was maintained for 6 months after the end of treatment [2].
