This doesn't work. I had nine sessions with no measurable difference. I am 30lbs overweight. They mentioned that their more expensive services work better on their clients. I thought they were up selling. Then I find out later that the reason they offer three extra sessions for the price of 6 is because Zerona hadn't been working on their clients. I wanted to believe Zerona works but it didn't do anything. When they say they can remove 7 inches it is from the whole body which is the same thing a sauna can do (temporarily).
