Actually Matty, you would be surprised... I have completely and utterly changed my lifestyle in 6 weeks... I am not trying the latest fad diets or anything like that, i have completely changed everything... Junk food simply doesnt tempt me at all any more!
The 2 hardest lesson i guess i have had to learn, are
1) you dont have to fill your belly every time you eat something.. If you eat the right foods, you can actually eat less than when you eat shit.
2) you absolutely dont need a gym membership to exercise and get fit.. Plenty of footpaths and parks around, just need a pair of joggers... I have gotten more use out of a $100 pair of runners in 6 weeks, than i got out of a 12 month gym membership. It is easier to get off ass and go for a walk or run around block, than get up and drive to a gym.
I used injuries for a long time to Leeroy.. I injured my back 15 years ago... and still use that excuse.. Would swimming be an option for you with your foot?
