all that happens with orlistat is that if you eat fat while on them, you get terrible runs - friend of mine tried it and literally had to dispose of several pairs of underwear as a result and complained of extreme stomach cramps. She was terrified of eating out and ended up not taking the tablets if we were going out - therefore defeating the object. The reason people lose weight on orlistat is that they're so terrified of the side effects that they won't eat fat, so best thing to do is just don't eat fat (Rosemary Connelly is a great low fat diet - she created it when she had gallstones and couldn't tolerate fatty foods). Just wanted to warn you about the dangers of orlistat....
