I have a stone I'd like to shift. During term time I'm pretty active as I walk a minimum of 5 miles a day. I've been fairly active over the summer too with a few 5/6 mile walks but nowhere near the daily amount I normally do. I also cycle once a week and do 11 miles along a cycle/leisure track (old railway line) but again its term time only. As soon as my youngest is in school full time from mid September then I'll be increasing my activity levels and getting back on my bike. I'll probably go twice a week seeing as he'll be full time at school now.
In addition to this I was thinking about swimming. There's a lovely pool a few miles away. How good is swimming in general for toning up and healing weight loss?
My diet is vegetarian and reasonably healthy but could be better, I don't drink on a regular basis, don't smoke, and despite chronic pain from endometriosis and a back that's in spasm I consider myself pretty healthy.
I have very limited funds and don't like the gym or classes so that works out well but I need to do more. I'm 43 and peri-menopausal and middle aged spread is creeping up on me 
Does this amount of activity sound like it will shift some lard if I address my chocolate consumption too?
