Yeah, my uncle actually told me about this legend. I thought he was joking, but he assured me it was true!
Really, in pakistan u don't know what they really put in the food. A few months ago in pakistan we all noticed that as soon as we had consumed no more than 3 mouthfuls of the food, we were really full up, couldnt eat more. This applied mainly to the bbq'd stuff. I really think they put something in the masala to make people not want to eat anymore bbq!
It will be great help for people who are dieting. No ?
