I have read through my new pack a couple of times and I think the bare bones are this;
Foods have been changed from being Free and Superfree to just free foods, except they now designate them as speed foods or protein-rich.
The Syns section of the new book gives values for EE only. Red and Green plans are still supported but SW are putting greater emphasis on EE and EE SP, Syn values for Red and Green will still be available online.
Notable changes are that certain things have been moved around, specifically, peas have been moved from the veggies section and are now with the beans as they are considered to be protein-rich (along with other leguminous veggies).
Pineapple is no longer considered to be a speed food and just counts as a standard fruit, like a banana (aw, guess I'm sticking to melon now!)
Chicken is no-longer listed as a speed food (I suspect this to be for the purposes of Clarity as they don't want people to fill their plates with just chicken and wonder why they have not had any losses at the scales).
Oyster Sauce has now been given Carte Blanche in the Storecupboard Staples section.
The re-released EE encourages you to fill your plate with 1/3 speed food.
EE still allows one HEA and one HEB
The emphasis of the additional plan (Known as Extra-Easy SP) which SW intend to supersede Success Express is to fill your plate about 50/50 with protein-rich and speed food to turbo boost weight loss.
EE SP allows you to have a couple of potatoes or a little rice so it's low-carb instead of no carb but you have a fine line between what is an EE SP meal and reverting to EE.
EE SP allows 1 HEA and 2 HEB.
