Losing the Weight

I have been losing an amazing amount of weight through the programme called Slimming World.  It's almost NOT a diet, because there is no weighing or measuring as a lot of the food is FREE.  Those foods that are NOT free have a SYN value (short for "synergy") and they use the double entendre as the word "sin".  You are allowed 15 syn values a day.  Since the beginning of September I have lost almost a stone!  I managed to get into my mother's tops this weekend, something I would never have thought possible over the years!  A lot of food is what's called Speeders and SuperSpeeders - plaice, lemon sole, cod, haddock, raspberries, strawberries, melons, blackcurrants just to name a few.  These speed up the weight loss.  I am happy to say that at the start (5 September) I was 12 stone 13 and I am now 12 stone 1.
Exercise has been difficult as I have a foot condition called Plantar Fasciitus, inflammation of the tendon underneath the foot, and the arch itself feels like its going to snap with every step.  I have 5 minutes of walking then the pain kicks in.  Injections, orthotic soles, exercises and painkillers have not worked, so it may mean surgery.  But if I try to slowly get the walking done I will.
