From what I remember the way my mate explained it was that fair enough if you dont eat the fat you dont need the pills but they stop all the fat being absorbed so even if you eat those those healthy meals that have a bit of fat in them it doesnt get digested. Its an extreme diet effectively that alot of people would be hard pushed to do normally without a hell of alot of help.
I know I cant stick to diets and if I was ever big enough that I had to go on a diet that meant my doctor prescribing me these pills I know I'd be more scared of shitting myself if I pigged out than of not losing weight. Little bit of added incentive
