I did a comparison last night between the bar and shake and you are losing out on vitimins with the bar. I suppose because you are only just getting the minimum nutrients it is advisable to only have one bar.
I wouldnt recommend it, the fact theyre not Exante products I wouldnt take the chance as you could be losing out on nutrients. Having 2 BL bars a day in effect means youre doing the BL diet which says you should have a meal too, its not worth the risk, it means youre doing neither diet properly and Id say thats asking for trouble
I completely agree with Starlight, you are best trying to stick with the diet best you can otherwise you are doing neither exante or BL as they are intended and may not be getting the nutrients you need. x
