My Chinese doctor friend who was a department head in Beijing, is pretty good at acupuncture, she is a qualified gynaecologist, and was telling me, how they use acupuncture as an anesthetic, when they do Caesarian deliveries, of which all of them are.
She tells me that acupuncture for weightloss, is not very good, common sense tells, you that, it cannot stimulate the heart fast enough, to lose weight....
The only effective drug is like amphetamines, which is dangerous because it can give heart attack. she says the only way, is to eat less and better choice, by improving the metabolic system gets the essential acids and coenzymes otherwise you do not function optimally....
The only way is exercise and controlled diet.
There is also a herb, although its been banned in many Countries, don't know about Singapore though..its called Ma Huang very effective, but its been abused so much. But I can guarantee you it works like amphetamine, and burns the fat
