At the end of the day, it's down to exercise.
Just eat crap and do exercise, job done
As Chirag says, if you want to go into serious body building etc, then a controlled diet and working out is the way forward, but if you want to lose weight then yes tone down your diet but don't suffer with crap food that you don't like. Just do a bit more exercise, Few push ups, Sit ups, running etc will do wonders.
I really should listen to my own advice.
