My Mum had a body wrap whilst on a cruise recently. It PROMISED to take three inches off you. My Mum was obviously up for that! They did all the measuring (thighx2, upper armx2, hips, waist, chest, etc) then wrapped her up. Left her sweltering for half an hour with nothing to drink, unwrapped her and remeasured (this time pulling the tape decidedly tighter) - proudly announcing "you have lost three inches". The measurements were much the same so Mum queried this, the breakdown was approximately as follows;- half an inch from each thigh, hips, middle and chest and a quarter inch from each upper arm: or nothing at all if you take into account the dehtdration she had suffered and the tension of the tape during second measurment. It is a tidy money making scheme but for weight loss I suggest a brisk walk!!
