I've lost about 60-65 pounds since I got my first bike in December, 2010. Some of that was from trying to ride 1,000,000 miles that first year, and since then injuries of one kind or another have taken me off the bike several times - mainly from stubborness on my part to ignore pain (hint to not do that). I've managed to stay active through it all however, and I think that is key. Also diet is even more key - research keeps showing that our food intake plays a larger role than exercise does in the long term. +1 on giving up the canned veggies, frozen is much better for you if fresh isn't an option. Murelalex has a great idea about trying one new thing a week - small steps might take longer to get us there but that are much easier to keep going.

Keep moving, even it is just a walk around the neighborhood, and mix things up for your body. My initial set of over-use injuries were born from my reluctance to do anything outside of riding or spinning class - the body needs to mix things up. Not that you would make that same mistake, I am just plain stubborn...
