does herbal body wrap guarantee inch lost on the belly?  

I am wondering if someone can help me with a question. a few of my frioends bought a 10 pack of herbal body wrap. they also asked me to wrap them. i of course agreed. while they were relaxing for 1 hour my friend asked me if i would like to be wrapped next. i thought this was a great idea... until, i took their after measurements. both of my friends lost at least 12 inches from all over their body.. i am not very thin but i am contented with the body i have now.. and i fell i can't go slimmer because i would look mummified if i would.. has anyone done this and what have your results been? did you lose any inches from taking an herbal body wrap bath? did you wear bottoms to keep the solution from getting into "places" it does not belong? i appreciate an and all comments on this subject.
