Metabolic Research center

I know someone that did it. They lost a ton of weight - FAST (for a wedding). I saw her two years later and she was back to her normal self. I wonder how much money she spent.
I think that center puts you on an 800 calorie a day diet which I consider dangerous. And expect them to try to sell you really expensive vitamins. You have to purchase the meal replacement drinks (expensive).
Here are some products they may push: ACV pills, raspberry keytones, b12/b6 vitamins, yohimbe herbs, garcina cambodia, blue green algea, hoodia.
Careful with their hormone testing since they could give everyone the same results just to sell the hormone balancing pills that contain iodine (which is in most multivitamins). The iodine pill contains 8,000% of the RDA.

All my alarm bells are ringing.

Here are some real reviews (not fake posts from their own sites).

Some reviews are from the company employees defending their product. Skim through those.
