I lost weight on my own this year. Between January & August I lost nearly 2 stones. Did it by watching calories, but more importantly going swimming 4-5 times a week. Not long swims, but 20 minutes a day. Walked there most days, about a mile each way. I need to get back on it again, which I will do at the beginning of the year as I have put on about half a stone since August, by not doing nearly as much swimming - laziness crept in after getting a sore shoulder which prevented swimming.
