I have lost 12 kg since moving back from Oz simply because I am outdoors more and excersing more. In Oz we lived next to the beach and the first couple of years we went a lot, but after that, pretty much never other than to walk the dog. Yesterday we were out walking a forest trail, day before a walk along a river, tomorrow, Falls of Clyde, Saturday will be Strathclyde Park as my wife is doing a Park Run there.
