Hi, welcome to our site. I am Dr Saumya Mittal. Read your query. That is a very significant question and i appreciate your problem. I will try my best to answer your query I have had a detailed look at this Amway product. It contains approximately 8 calories per 250 ml, or so they have claimed. Outside of that, the contents are largely multivitamins. I would therefore suggest that instead of taking this energy drink, you just put him on multivitamin tablets. Not only will that be cheaper, it will also save those 8 calories, in case he is fighting high and uncontrolled sugars. As for the weight loss, its a part of the diabetes. In fact to a certain extent I would say that loss of weight is good for a diabetic. It reduces the insulin resistance in the body. In fact loosing weight is a standard advice every type 2 diabetic is given. So i think you need not worry too much about loss of weight I hope this helps you. Inform the reports mentioned above so i can be of help further. Best of luck. I have given you the answer to the maximum considering the information provided. The results of the tests could further enhance my answer to you. Please do understand that some details could be extracted from a detailed history and examination. Looking forward to your return query with the details asked so that I can help you further. (If the answer has helped you, please indicate this)
