Any time you eat less protein than you were, it's moving in the direction of pink. The diet % and numbers are only a guideline, it's not the type of diet where you have to do exactly perfect or you sway blue.
THere are about 40 g of protein in 1/2 a chicken breast, that is the minimum amount for the LE Diet. The trouble is that then you need to eat other foods too and those will also have some amount of protein in them. So you are eating pretty much ALL your protein in one sitting and getting barely any calories and fat when you do. It can make it difficult to stick with diet to continue eating chicken. IT is not so much about how it sways per se, it's because eating nothing but chicken and fruit and sugar is a starvation diet that is unsustainable for people in the long term and not healthy pre-pregnancy anyway. YOu need to be able to include a variety of foods in your diet to be certain you're getting adequate nutrients and also because otherwise you'll go nuts and end up cheating.
