Green is my favourite, I love it - so easy, so many yummy things to eat, and I never feel hungry on a green day.
I get better losses on red but struggle to feel inspired for meals - tends to be meat of some description with steamed veg, which never seems that appealing. The exception is when I do slow cooked stews, casseroles etc, or shepherd's pie. Always feel like red days take more planning, whereas on green I feel I can be more spontaneous depending what I fancy.
I've not really done many EE days since I tried red and green. I usually use my Hexs for breakfast so I feel like I'm missing out by not getting the extra A and B to use later in the day. Also find it hard to stick to the 1/3rd superfree, and so don't get the losses I do on red and green. It is definitely the better plan if going out for a meal, though!
