Hi there, I have been reading up about this as I wondered the same as you. I believe that although it does work (Im sure)by making us far more aware of the fat content of food because we're scared to death of the side effects, it works in another way too. Because it blocks fat from entering our system, the small amount of fat which does get in may not be enough as we do need a certain amount in the diet, so the body gets the rest that it needs from the fat we already have stored which is the very fat we all want to get rid of so badly.So in theory it should work. I hope this all makes sense and wish you lots of luck and hope you do really well in your next tests! Jx
