Thinking about moving to 810 tomorrow after see cdc. Have been ss for last 4 weeks and lost over a stone (not counting my weigh in tomorrow) but need to go for keyhole surgery in next 2-3 months. I am waiting for appt coming through. Want to be off Cambridge and healthy eating for then. Can't deciede wether to ss for another 3-4 weeks or move to 810 now. Have been looking for link with details of 810 now with prawns / eggs etc but can't find it. Can someone point me in right direction.
