I had ordered Linea 7 and am a size 18 and weigh 102 kg...i am a bigger person and have not lost any weight my sister has also tried it as she wanted to lose a couple kg fora friends wedding and she to has not lost any weight and we both ate healthy...i belive that this does not work whethere you are small or big...my opinion dont buy it and go to y our local doc and get something that does work it may take longer but atleast you get a pamphlet with the side affects and you have a reel doctor to ask questions to and can see a qualifications certificat %-)
