Maybe try the top video - warm up - before and after your walks. Before I got a fitness trainer to really help lose weight, I was up to 1.5 hours of walking 5-6 times a week and it did nothing but kill my hips and knees. He got me to stretch 15 minutes before and after, and walk 20-30 minutes. BOOM - I felt so much better and the weight started coming off.

But that was also when I went organic too. The pesticides, colors, flavors, gmos and other additives are really bad for your system. My food became much cheaper. You really have to make an effort at it,but you can find cheap organic food. Check the sale bins. It is often there at a good price.

Yes, the regular salt is horrible. The "iodine" is industrial waste that would have to go through EPA hoops if they did not sell it for food.

I was able to eat Italian and Mexican pasta when I was in the states. I also stated baking my own bread with a bunch of different organic flours I found cheap. That was a real treat and not hard. I do not have an oven here, and sure miss my bread :)
