There is no fast route really. Some people lose weight better on red/green, some on EE but your body will decide how quickly it loses the weight.
We have people who consistantly lose 2-3lb a week and some who lose half to 1 lb a week.
Just eat the foods you like and enjoy them - don't rush the losses, you didn't put it on overnight, you won't lose it overnight.
Losing steadily is the key to keeping the weight off long term.
Don't forget, you can do a day or two of EE and some red and some green, you don't need to do all EE. Just plan your meals and the day will fit in around it!
