Here I am about to start on the Cambridge Diet again. I lost around 5 stones 7 years ago and managed to maintain for around a year, I then had a spinal fusion due to a long term back injury and gradually over the years I have put around 4 stones back on. I see my consultant on Tuesday and can't wait to start again, I feel bloated, lethargic and generally awful at the moment. I know I can do the diet having been successful before, the hard part is going to be maintaining! Any tips/encouragement appreciated!
