Liar, personal experience, friend, he will make you tea first, and then let you pay when you feel better, saying that it was only a conditioning period before, and there was a weight loss period, and the cost of weight loss period was several times that of conditioning period. They just took advantage of your idea of "reducing it to the end" In the end, it was just a lie. Don't be cheated. Of course, if you have money and want to try, you can.
