I too was cynical about using non Exante bars, then ran out of bars and thought I might as well try Tesco ones. I have and what a difference in taste, not that great but it's something different. This is my 5th month on the diet and to be honest, am fed up of the same stuff. In my opinion we are all different and we have to do whatever works for us. If for me adding Tesco/Asda/BL bars will take me to goal so be it.
