I agree with last reply. You don't have to eat fatty unhealthy food just because you don't want to starve yourself.Life may be "too short" but why possibly make it shorter. If your that botherd about losin weight,then do something about it, Eat healthy and exercise. And your wrong about gyms,lots of folk go because they are well overweight and need to exercise. You'll need at least twenty mins before you start burning fat though. Any exercise is better than none,strengthen your heart,give you more stamina,strengthen muscles. Look at a beginners aerobic class maybe. I honestly believe you'd enjoy some form of exercise once you get into it.
At home,I uppose there's always Aussie aerobics on SKY you could join in with. quite enjoyable
