Isagenix Supplements

I need some advice. I am currently seeing an accupuncturist, and the results have been great. My accupuncturist would like me to start a 30 day cleanse using the Isagenix supplements. A good cleanse is always good, am i wrong? i have done some research on this company and some say it’s just a pyramid scheme. yes i am overweight, but 800 kcal a day doesn’t sound good for the system. so, please give me some advice.

thanks
