There's no suggestion in the article that acupuncture and related therapies are a standalone treatment for obesity. The article clearly states that the use of Traditional Chinese Medicine is for "balancing" [energies and health]. The clinic treatment is based on the proven Western techniques of educating the person to live and eat healthily.
"No matter how exotic all that sounds, at the core of every weight-loss scheme still lies the all-important balance between the amount of calories consumed and burned, Dr. Li says."
"...our goal is to help patients adopt healthy living and eating habits".
In my opinion, if a person applies the excellent basic principles stated by Dr Li in the article about adopting healthy living and eating habits then the other, culturally mandated treatments such as acupuncture are superfluous.
In fact, I suspect exotic treatments would serve to distract a person from fully confronting and treating his or her underlying behavioural and emotional problems that caused their obesity and general poor health in the first place. And remember, a person can have the most wonderfully balanced mental outlook, be happy and feel great, have no emotional issues - but if they eat too much crap they'll still get fat.
