I used to walk about 3 miles to work every weekday when I was working, which kept me reasonably fit and physically healthy. I retired two years ago and became a couch potato. I think that contributed to my T2 diagnosis this year. I was also comfort eating more sugary stuff because I had more time on my hands, and put on over a stone.
Since being diagnosed I have started walking again. For the first three months until my retest I aimed at 20,000 steps a day, to lose as much weight as I could (along with LCHF and diet). I lost about 1 stone and 7 lbs.
Now I aim to walk 10-15,000 steps a day. I could do more as I have more energy as I lose weight and get fitter, but I don't want to risk getting Plantar Fasciitis in my feet again. I got that a few years back when I was walking 25,000+ steps a day. It is really painful and stopped me walking much for almost a year.
I do use a pedometer as it helps to motivate me, though I know now roughly how much I need to do - about 1 hour's walking. I generally walk to my local park, walk three times around it, and back home. I have now lost 2 stone, and my HbAic was down from 49 to 44 at my 3 month test.
I do quite enjoy walking. When I was younger and could walk faster I used to feel like I was almost flying along with my feet hardly touching the ground! I used to go on walking/trekking holidays in the UK and around the world, but now I would rather sit around a pool or on the beach.
