I've found that I do actually have better losses when I stick to a full red week, but I do get hungry easier (probably because the green days pasta, rice, potatoes etc are much more filling and my body craves them) so I tend to end up spending a lot more money buying extra chicken to fill up!
A full week on green used to be my norm at the start because I always seemed to be so hungry, and although I'd still have ok losses, they weren't as good as on a red week, even when I made sure I was adding in as many speed symbol foods as I could.
I've been doing EE since it came out because I enjoy the variety and choice, and even though I reckon I'd have a better loss by sticking to red I rarely do that.
Whatever plan you're on works! Our food preferences and the way our bodies deal with the foods we eat, can vary a lot so I would say that you should give green your best shot, keeping up those speed symbol foods and keeping up your fluid intake and who knows, your body might just get a boost and you might even loss more!?
Best o'luck with it anyways!
