I too prefer EE, although I do sometimes have just 'SP' meals within my normal EE days, just to try to limit the amount of carbs I consume.
I've lost quite a lot of weight, pretty much exclusively using the EE plan...but now it is becoming a little harder to see the weight coming off as I would like, that's why I slip in a bit of SP here and there.
As my consultant says, "The more speed you choose, the more you'll lose!"
Good luck with your journey. I love the plan...definitely a lifestyle change rather than a diet.
