 I am Dr. Sumit Alwath, I am the Chairman of Paryatric Surgery at Manipal Hospital Bangalore. Well, currently there are no medications which are available in the powder or drink form which can help you in losing weight. There are two or three medicines which are available in India for weight loss which should be taken only under doctor supervision. A couple of them are in the pipeline which can probably help people to lose weight. But I am not aware of any powders or drinks which are available to help people lose weight.
